3. Need regex for incremental by 1

Need regex for incremental by 1


  • Hi all,

    I have the texts like "indent=“0”, indent=“1”, indent=“0”, indent=“2” etc in several places in the xml file.

    I wanted to replace with incremental by 1 in to the each value as indent=“1”, indent=“2”, indent=“1”, indent=“3” etc.

    Is there any possible way available in notepad++?

    thanks

    There is no way to do it within Notepad++ without scripting. See the following:

    Well…it depends upon how much effort you want to expend…

    Say you used the Edit (menu) -> Column Editor… feature (twice) to create a two column table of incrementing numbers (it could be a long table, I just show a short one):

    0 1
1 2
2 3
3 4
...

    and then you put a line of dashes (or any sequence of characters that does not appear in your data) and this table AFTER your data in your Notepad++ tab:

    I have the texts like "indent="0", indent="1", indent="0", indent="2" etc in several places in the xml file.
-----
0 1
1 2
2 3
3 4

    Then a regex replacement could solve this problem:

    Invoke Replace dialog (default key: ctrl+h)
    Find what zone: (?-i)indent="(\d+)"(?s)(?=.*?^-----.*?^\1\h+(\d+))
    Replace with zone: indent="\2"
    Wrap around checkbox: ticked
    Search mode selection: Regular expression
    Action: Press Replace All button

    Results:

    I have the texts like "indent="1", indent="2", indent="1", indent="3" etc in several places in the xml file.
-----
0 1
1 2
2 3
3 4

    After that you simply remove the line of dashes and the table…

    Thanks very much!

    I will do this way…

  • ok, and another exemple.

    If I have 100 .html pages, and in each page I have such as:

    page 1:
    $item_id = 0001;
    page 2:
    $item_id = 0002;
    page 3:
    $item_id = 0003;

    How can I replace with incremental by 1 in to the each value, in order to obtain:

    page 1:
    $item_id = 0002;
    page 2:
    $item_id = 0003;
    page 3:
    $item_id = 0004;

    etc…

    What is the meaning of “page” in this context…do you have 100 html files and you want to do this operation on each file ?

  • I have 100 .html pages, and each page has a unique string. For exemple, page 1 has $item_id = 0001;, page 2 has $item_id = 0002; etc…

    I want to replace in each file with incremental by 1 in to the each value

    It sure seems like you could use a variation on the technique described above:

    • key concept: use Replace All in All Open Documents or Replace in Files for most of the action
    • create a delimiter and a lookup-table running from 0 to 101 (or whatever), probably all on one line is best, e.g. \r\n-----0:1,1:2,2:3,3:4,4:5,5:6,6:7,7:8,8:9,9:10,10:11,… ; you can do this with the column-editor features to ease the pain…followed by some editing…
    • regex replace \z in each file with the lookup table string created above (this will add the table at the end of each file)
    • run a regex replacement (on all files) like described above for the other poster but customized for your data, e.g. \$item_id = \d+; and the contents of the lookup-table string
    • craft another regex replacement to remove the delimiter and lookup-table from all files
