deplace a block to an other place



  • Hi, @kat75,

    Here is my contribution, to your problem ;-)

    Let’s suppose you have two files 1.html and 2.html, as below :

    <!-- 1.html -->
    Some text
    before the
    "noscript" tag
    <noscript class"text" lang="example">
    line1
    line2
    line3
    line4
    </noscript>
    bla
    bla
    bla
    blah
    <img… and …style="display:none;"></div>
    And some text,
    located after
    ............
    <noscript>
    ............
    

    and

    <!-- 2.html -->
    bla
    bla
    <noscript>
    bla
    
    <noscript class"text" lang="otherexample">
    Other line1
    Other line2
    Other line3
    Other line4
    Other line5
    </noscript>
    Other text…
    etc…
    etc…
    etc…
    <img… other and …style="display:none;"></div>
    Other Text
    ..........
    till the END of the file
    
    • Move back, at the very beginning of current file ( Ctrl + Origin )

    • Open the Replace dialog ( Ctrl + H )

    • Select the Regular expression search mode

    • In the Search what: box, type in the regex (?s)(<noscript class.+?</noscript>\R)(.+?style="display:none;"></div>\R)

    • In the Replace with: box, type in the regex \2\1

    • Click on the Replace All button

    => Your two html files should be modified, as below :

    <!-- 1.html -->
    Some text
    before the
    "noscript" tag
    bla
    bla
    bla
    blah
    <img… and …style="display:none;"></div>
    <noscript class"text" lang="example">
    line1
    line2
    line3
    line4
    </noscript>
    And some text,
    located after
    ............
    <noscript>
    ............
    

    and

    <!-- 2.html -->
    bla
    bla
    <noscript>
    bla
    
    Other text…
    etc…
    etc…
    etc…
    <img… other and …style="display:none;"></div>
    <noscript class"text" lang="otherexample">
    Other line1
    Other line2
    Other line3
    Other line4
    Other line5
    </noscript>
    Other Text
    ..........
    till the END of the file
    

    I do hope that it’s the kind of Search/Replacement what you expect to !


    Notes :

    • I suppose that the ending tag </noscript> ends the current line, in your html files

    • I suppose the the text <img………style="display:none;"></div> ends the current line, too

    • As usual, the (?s) modifier means that a dot regex character represents any single character ( Standard or EOL chars )

    • Then, the part <noscript class.+?</noscript>\R looks for any complete individual noscript block ( Note that the form .+? stands for the smallest non-null range of characters, between the two strings <noscript class and </noscript> )

    • This noscript block, with the final EOL characters ( \R ), is stored as group 1, due to the enclosed parentheses

    • Finally the part .+?style="display:none;"></div>\R searches for the smallest range of characters till the string style=“display:none;”></div>

    • Again, this block of lines, with the final EOL characters ( \R ), is stored as group 2, due to the enclosed parentheses

    • In replacement, we just rewrite these two groups, in a reverse order ! ( \2\1 )


    Remarks :

    • As previously said, for 400 files about, you should use the Replace in Files feature ( Ctrl + Shift + F )

    • Group all your html files, which have to be modified, in a particular folder

    • Do a BACKUP of this folder ( One never knows ! )

    • Fill up the Filters and Directory boxes, too

    • Click on the Replace in Files button, to perform a global replacement, on all your files

    • IMPORTANT : Do NOT use the v7.4 or v7.4.1 version of N++. Indeed, with these last versions, there a bug, when multiple S/R are performed : a part of the files scanned are not changed -:((( Refer to :

  • hello
    just awake
    thanks peter, claudia and guy
    guy its magic, seems to work fine, i didnt thank that it was so easily possible
    i must know how it works and donwload a previous version of notepad++ i have v7.41
    really fantastic
    a great thanks



  • @kat75 Guy often performs magic with Regular Expressions. :) And I believe he speaks French also.

    A good starting point for Regular Expressions is http://www.regular-expressions.info/



  • thanks glen for the link
    i shall try to learn regular expressions, there are really possibilities



  • hello
    i have a question
    i am trying to understand how what has given to me guy works
    (?s)(<noscript class.+?</noscript>\R)(.+?style=“display:none;”></div>\R)

    if i try to get an other sequence between a a tag by example… i got nothing! what is wrong?

    (?s)(<a href.+?</a>\R)

    with an img tag it doesnt take the first “> why? :-) thanks
    (?s)(<img class.+?”>\R)



  • @kat75

    without having the data we cannot say for sure what went wrong.
    So, in theory, the hyperlink regex would match everyhting within the tag if
    closing tags is directly followed by an eol char (no space)
    and the image regex would match starting with <img class followed by
    anything until ”> appears, followed directly by an eol char.

    Cheers
    Claudia



  • at the end it must be a eol character, ok i understand now



  • i would to say thanks to all, i have well succeed to move my block and begin to understand a bit notepad++
    is there a way to send private messages on notepad community, i dont find how



  • Hello
    do you think that its possible to move a block not to the bottom but to the top?
    i dont succeed
    i mean that in this example, how to move <img etc… and …style=“display:none;”></div> just before <noscript class"text" lang=“example”>

    1.html
    <noscript class"text" lang=“example”>
    line1
    line2
    line3
    line4
    </noscript>
    some text…
    etc…
    etc
    <img… and …style=“display:none;”></div>

    2.html
    <noscript class"text" lang=“otherexample”>
    otherline1
    otherline2
    otherline3
    otherline4
    </noscript>
    othersome text…
    etc…
    etc etc
    <img… other and …style=“display:none;”></div>



  • Hello, @pouemes44, and All,

    Here is, below, the general method in order to switch two consecutive blocks of text, separated, or not, by some stuff text

    So let’s start with the example text, below :

    bla
    bla
    bla
    Block 1
    of
    some
    text
    End block
    bla bla
    bla bla
    bla bla
    bla bla
    Block 2
    with some
    other text
    End block
    bla bla bla
    bla bla bla
    bla bla bla
    

    To correctly determine the limits of your block of text, whatever it is, you, necessarily, need to know :

    • The location of the beginning of your block. In our example, I suppose that it’s the regex ^Block \d+

    • The location of the end of your block. In our case, I suppose it’s the string End block

    IMPORTANT : In our example, the second block has the same limits as Block 1, but it could, perfectly, have some other limit definitions !

    So, from the above definitions, we can build the regex S/R, below :

    SEARCH (?s)(^Block \d+.+?End block)(.*?)(^Block \d+.+?End block)

    REPLACE \3\2\1

    Notes :

    • The leading (?s) modifier means that the special dot character represents, absolutely, any single character. Now :

    • The first part, (^Block \d+.+?End block, represents a complete individual block of text, stored as group 1

    • The third part, (^Block \d+.+?End block), stands, again, for an other complete block of text, stored as group 3

    • The middle part, (.*?), is the shortest range, even empty, of any character, between these two consecutive blocks of text

    • In replacement, we just switch the group 1 and 3, with group 2 standing as a pivot

    And, after a click on the Replace All button, you should get the expected text , below :

    bla
    bla
    bla
    Block 2
    with some
    other text
    End block
    bla bla
    bla bla
    bla bla
    bla bla
    Block 1
    of
    some
    text
    End block
    bla bla bla
    bla bla bla
    bla bla bla
    

    Just note that, if the two blocks are strictly consecutive, without the bla bla lines, as below :

    bla
    bla
    bla
    Block 1
    of
    some
    text
    End block
    Block 2
    with some
    other text
    End block
    bla bla bla
    bla bla bla
    bla bla bla
    

    We still get the correct modified text :

    bla
    bla
    bla
    Block 2
    with some
    other text
    End block
    Block 1
    of
    some
    text
    End block
    bla bla bla
    bla bla bla
    bla bla bla
    

    Now, Pouemes44, let’s apply this general method to your particular problem :

    The general template, of your first block, is :

    <noscript......
    ......
    ......
    ......
    ......
    </noscript>
    

    The general template, of your second block, is :

    <img.........
    .......
    .......
    .......
    style="display:none;"></div>
    

    Therefore, the corresponding regex S/R, in your case, is, obviously :

    SEARCH (?s)(^<noscript.+?</noscript>)(.*?)(^<img.+?style="display:none;"></div>)

    REPLACE \3\2\1

    So, considering your example, below :

    1.html
    <noscript class"text" lang="example">
    line1
    line2
    line3
    line4
    </noscript>
    some text…
    etc…
    etc
    <img… and …style="display:none;"></div>
    
    2.html
    <noscript class"text" lang="otherexample">
    otherline1
    otherline2
    otherline3
    otherline4
    </noscript>
    othersome text…
    etc…
    etc etc
    <img… other and …style="display:none;"></div>
    

    After performing the above S/R, you’ll get the modified text, as expected to :

    1.html
    <img… and …style="display:none;"></div>
    some text…
    etc…
    etc
    <noscript class"text" lang="example">
    line1
    line2
    line3
    line4
    </noscript>
    
    2.html
    <img… other and …style="display:none;"></div>
    othersome text…
    etc…
    etc etc
    <noscript class"text" lang="otherexample">
    otherline1
    otherline2
    otherline3
    otherline4
    </noscript>
    

    Et voilà !!

    Best Regards,

    guy038

    P.S. : Beware that, on our NodeBB site, text, containing starting and ending usual simple and double quotes, are changed into their Unicode equivalents, below :

    • Starting simple quote , of Unicode code-point \x{2018}, instead of the single quote sign ' ( x{0027 )

    • Ending simple quote , of Unicode code-point \x{2019}, instead of the single quote sign ' ( x{0027 )

    • Starting double quote , of Unicode code-point \x{201C}, instead of the double quote sign " ( x{0022 )

    • Ending double quote , of Unicode code-point \x{201D}, instead of the double quote sign " ( x{0022 )

    Notes :

    • For ANSI encoded texts, to avoid the nasty message Find: Invalid regular expression, the **correct regex syntaxes are, respectively, \x91, \x92, \x93 and \x94

    BTW :

    • Remember that the \x{####} regex syntax can be used :

      • For search of a true ASCII character, between \x{0000} and \x{007F}, in ANSI encoded files

      • For search of any Unicode character, between \x{0000} and \x{FFFF}, in UNICODE encoded files

    • Remember that the \x{##} regex syntax can be used :

      • For search of a true ASCII character, between \x{00} and \x{7F}, in ANSI encoded files

      • For search of any Unicode character, between \x{00} and \x{FF}, in UNICODE encoded files

    • To end with, remember that the \x## regex syntax can be used :

      • For search of any Unicode character, between \x00 and \xFF, either, in UNICODE or ANSI encoded files


  • a great thanks guy
    that was this part (.*?) i missed



  • i have an other question
    if i search (?s)(<h1.+?</h1>\R) i got a result in my file

    but if i search (?s)(<a.+?</a>\R) to get <a href=“mypage.htm” title=page">page</a> i got nothing why? what is wrong?



  • Hello, @pouemes44,

    • In the regex (?s)(^Block \d+.+?End block)(.*?)(^Block \d+.+?End block), of my previous post, the part (.*?) represents the shortest range of characters, even empty, stored as group 2, between the two consecutive blocks of text, that are to be swapped !

    Now, if we consider the HTML example text, below :

    <td height="15">
        <font size="2" color="black" face="arial, verdana"><b>Lire un message / dossier : Reçus</b></font> 
    </td>
    
    <td height="15">
        <font size="2" color="black" face="arial, verdana"><b>Lire un message / dossier : Reçus</b></font> 
    </td>
    

    Beware about the two different behaviours :

    • The regex (?s)<td.+</td> looks for the largest range of characters .+, between the strings <td and </td> => It matches all the text, at once

    • The regex (?s)<td.+?</td> looks for the shortest range of characters .+?, between the strings <td and </td> => it matches, successively, each block <td…</td>


    Now, regarding your HTML text :

    <a href=“mypage.htm” title=page">page</a>
    

    I suppose that you do NOT get a match, using the regex (?s)(<a.+?</a>\R), because, probably, it’s the last line of your current file, which is NOT followed by any End of line character !

    Indeed, in that case, the ending part \R cannot match anything. So the overall match fails :-((

    Two solutions :

    • Use the regex (?s)(<a.+?</a>\R?). With that syntax, the \R part is optional

    • Add a line break to this last line !

    For a better visualization of the End of line characters, just click on the icone

    Cheers,

    guy038



  • Hello Guy
    i just see your answer
    a great thanks, yes work with (?s)(<a.+?</a>\R?)
    a real thanks for all your explanations, i already succeed to do wonderful things with them.



  • Hi, All,

    I’m back for additional information, about lazy, greedy and possessive quantifiers. it’s fundamental to, correctly, understand the differences, between these 3 types of quantifiers !

    So, let’s consider the simple text 12345ABCDE, in a new tab

    How the regex engine interprets, for instance, the regex \w{1,10}[A-Z]{5}, with the greedy quantifier {1,10} ?. Well :

    • It, first, tries to match the LONGEST range of \w => 10 Word characters. But, the part [A-Z]{5} CANNOT match anything

    • Then, it backtracks and tries the first 9 Words characters. Again, the part [A-Z]{5} does NOT match the E letter

    • Then, it backtracks and tries the first 8 Words characters. Again, the part [A-Z]{5} does NOT match the DE letters

    • Then, it backtracks and tries the first 7 Words characters. Again, the part [A-Z]{5} does NOT match the CDE letters

    • Then, it backtracks and tries the first 6 Words characters. Again, the part [A-Z]{5} does NOT match the BCDE letters

    • Then, it backtracks and tries the first 5 Words characters. This time, the part [A-Z]{5} DOES match the ABCDE letters

    => After the backtracking phase, all the text is matched and selected !


    Now, how the regex engine interprets the regex \w{1,10}?[A-Z]{5}, with the lazy quantifier {1,10}? ?

    • It, first, tries to match the SHORTEST range of \w => 1 Word character. But, the part [A-Z]{5} CANNOT match the 2345ABCDE string

    • Then, it backtracks and tries the first 2 Words characters. Again, the part [A-Z]{5} does NOT match the 345ABCDE string

    • Then, it backtracks and tries the first 3 Words characters. Again, the part [A-Z]{5} does NOT match the 45ABCDE string

    • Then, it backtracks and tries the first 4 Words characters. Again, the part [A-Z]{5} does NOT match the 5ABCDE string

    • Then, it backtracks and tries the first 5 Words characters. This time, the part [A-Z]{5} DOES match the ABCDE letters

    => After the backtracking phase, all the text is matched and selected !

    Note : Instead of the English werb backtrack, the verb fortrack would be more adapted ! Sorry, English isn’t my mother tongue !


    Finally, how the regex engine interprets the regex \w{1,10}+[A-Z]{5}, with the possessive quantifier {1,10}+ ?

    • It, first, tries to match the LONGEST range of \w => 10 Word characters. But, the part [A-Z]{5} CANNOT match anything

    • Now, the normal process would be to backtrack. But this action is forbidden, due to the possessive quantifier ! In other words, once a match has been found, for the first part \w{1,10}+, the following parts of the regex must match the remaining of the text. But, as the first regex part have consumed all the text, the part [A-Z]{5} will NEVER match anything !
      So, the overall match fails and you get the normal message Find: Can’t find the text "\w{1,10}+[A-Z]{5}"


    Using, again, the same example 12345ABCDE, in a new tab, it’s easy to verify that :

    • The regex \w{1,10} matches the longest Word characters range => The whole string 12345ABCDE is matched

    • The regex \w{1,10}? matches the shortest Word characters range => The 1 Word character is matched, then the 2 digit and so on…

    • The regex \w{1,10}+ matches the longest Word characters range => The whole string 12345ABCDE is matched, too !


    So, to sum up, here is, below, a list of all the quantifiers :

        GREEDY     quantifiers   :    *  ( = {0,} )       + ( = {1,} )      ?  ( = {0,1} )      {n}        {n,}        {m,n}
    
        LAZY       quantifiers   :    *? ( = {0,}? )     +? ( = {1,}? )     ?? ( = {0,1}? )     {n}?       {n,}?       {m,n}?
    
        POSSESSIVE quantifiers   :    *+ ( = {0,}+ )     ++ ( = {1,}+ )     ?+ ( = {0,1}+ )     {n}+       {n,}+       {m,n}+
    

    Remark : The two {n}? and {n}+ syntaxes, although correct, are useless, as the syntax {n} could be qualified as an EXACT quantifier !

    Best Regards,

    guy038
