    With the help of a Regex, how to find "code" preceded by a "<" only if "code {" is absent between "<style" and "</style>" in the css section which is below ?

      I have relied on the explanation of the (*SKIP)(*FAIL) method mentioned at https://community.notepad-plus-plus.org/topic/26812/generic-regex-how-to-use-the-couple-of-backtracking-control-verbs-skip-fail-or-skip-f-in-regexes/5

        An alternative Regular expression can be to introduce a negative lookahead between .*? and the code just after it in this Regex: <code.*?code\x20\{\s*font-family

          Hello, @dr-ramaanand and all,

          If I assume that any line <style .....> always comes right after a line <code....>....</code>, a possible solution is :

          (?s-i)<code(?:(?!</style>).)+?</code>(?=\R<style (?:(?!code ?{).)*?</style>)

          Test it against this sample text :

          <code............>............</code>
<style type="text/css">
code {
  font-family: &quot;verdana&quot;;
  font-size: 19px;
  color: black;
  font-weight: bold !important;
  line-height: 1 !important;
  }
}
</style>

<code............>............</code>
<style type="text/css">
</style>

<code............>............</code>
<style type="text/css">
code{
  font-family: &quot;verdana&quot;;
  font-size: 19px;
  color: black;
  font-weight: bold !important;
  line-height: 1 !important;
  }
}
</style>

<code............>............</code>
<style type="text/css">
</style>

<code............>............</code>
<style type="text/css"></style>

<code............>............</code>
<style type="text/css">
code {
  font-family: &quot;verdana&quot;;
  font-size: 19px;
  color: black;
  font-weight: bold !important;
  line-height: 1 !important;
  }
}
</style>

          As you can see, it select only the line <code....>....</code> when the following section <style .....</style>, possibly multi-lines, does not contain any string code { or code{ !

          Notes :

          • I do not use any Backtracking Control verb

          • In the section <code....</code>, it must not contain any string </style>

          • In the section <style ....</style>, it must not contain any string code { or code{

          If you prefer to look for the string <code only and not all the zone <code....>....</code>, use the following regex :

          (?s-i)<code(?=(?:(?!</style>).)+?</code>\R<style (?:(?!code ?{).)*?</style>)

          Best Regards,

          guy038

            @guy038 There is a lot of text between the <code and <style (or more appropriately, between the </code> and <style) and yes, I want to find just <code. I think you need to introduce a .*? somewhere in the middle of the Regex, to find what is between <code and code\x20\{\s*font-family. The \x20 is to match a single white space, the \ just before the { is to help escape it and help match the { and the \s* is to match more than one white space, even if they are on the next line or a couple of lines below, as long as everything is a white space.

            I actually have this block to match the above:-

            <code............>............</code>
A lot of text here, spanning many lines
<style type="text/css">
code {
  font-family: &quot;verdana&quot;;
  font-size: 19px;
  color: black;
  font-weight: bold !important;
  line-height: 1 !important;
  }
}
</style>
Some text/codes here
<div id="google_translate_element"></div>
<script type="text/javascript">
Some javascript here
</script>

            I also want your Regular expression - RegEx - to skip any <code between <div id="google_translate_element"></div>\s*<script type="text/javascript"> and </script> - there are many <script tags and so, it should skip what is between <div id="google_translate_element"></div>\s*<script type="text/javascript"> and </script> as well as any <code between </code> and <style

            This RegEx worked but maybe you can improve upon it: (?s)(<code.*?code\x20\{\s*font-family|<div id="google_translate_element"></div>\s*<script.*?</script>)(*SKIP)(*F)|<code

              Hi, @dr-ramaanand and all,

              Ah…, OK. So I changed my line of reasoning :

              Instead of looking for zones which do not contain the string code\x20?{, I’m looking for sections which do contain the string code\x20?{

              Then, using the well-known backtracking control verbs (*SKIP)(*F), I omit these cases and look for the string <code, in all the other cases !!

              Thus, the following regex should solve your problem :

              (?xs-i) <code (?:(?!</style>).)+? </code> (?:(?!</style>).)+? <style\x20 (?:(?!</style>).)*? code\x20?{ .+? </style> (*SKIP) (*F) | <code

              Test it against the sample text, below :

              <code............>............</code>
<style type="text/css">
code{
  font-family: &quot;verdana&quot;;
  font-size: 19px;
  color: black;
  font-weight: bold !important;

                @guy038 Your RegEx doesn’t skip what is between <div id="google_translate_element"></div>\s*<script and </script> (the \s* is to match any number of white spaces in between, even if it is on the next line). Is there any mistake in this RegEx: (?s)(<code.*?code\x20\{\s*font-family|<div id="google_translate_element"></div>\s*<script.*?</script>)(*SKIP)(*F)|<code ? I think it works.

                  Hello, @dr-ramaanand and all,

                  Your requests are quite complex. So I imagined a completely different way to solve the different required conditions !

                  We’ll add one special character, right before any string <code, beginning a line, when the conditions are not respected

                  Thus, perform, successively, these two regex replacements :

                  SEARCH (?xs-i) ^ <code (?: (?! <code ). )+? code \x20? {

                  REPLACE \x{2588}$0

                  We’re searching, here, for the string code\x20?{ !

                  And

                  SEARCH (?xs-i) ^ <code (?: (?! <code ). )+? google_translate_element

                  REPLACE \x{2588}$0

                  We’re searching, here, for the string google_translate_element !

                  Now, it’s quite trivial : simply search for the regex (?-i)^<code which should be the allowed cases, ONLY !

                  If you test it against my previous sample text, you should get the following modified text :

                  █<code............>............</code>
<style type="text/css">
code{
  font-family: &quot;verdana&quot;;
  font-size: 19px;
  color: black;
  font-weight: bold !important;
  line-height: 1 !important;
  }
}
</style>

<code............>............</code>

}

  }
}

█<code............>............</code>

  }
}
</style>

                  After analyzing your text, simply run this replacement :

                  SEARCH \x{2588}

                  REPLACE Leave EMPTY

                    @guy038 This RegEx worked for me: (?s)(<code.*?code\x20\{\s*font-family|<div id="google_translate_element"></div>\s*<script.*?</script>)(*SKIP)(*F)|<code - thanks for your time anyway

                      Hi, @dr-ramaanand and all,

                      I do not understand why you think that the following regex is OK !

                      (?s)(<code.*?code\x20\{\s*font-family|<div id="google_translate_element"></div>\s*<script.*?</script>)(*SKIP)(*F)|<code

                      Apparently, against the sample text, used before and pasted in a new tab :

                      <code............>............</code>
<style type="text/css">
code{
  font-family: &quot;verdana&quot;;

                      It just selects the last line beginning with <code !

                      However, in a previous post, you said :

                      it should skip what is between <div id="google_translate_element"></div>\s*<script type="text/javascript"> and </script> …

                      And, precisely, this last line beginning with <code, is, indeed, followed, further on, with the block :

                      (?s)<div id="google_translate_element"></div>\s*<script type="text/javascript">.+?</script>

                      Thus, it should not have been matched ?!

                      Anyway, if this regex above seems to work nicely for you, that’s the main thing !

                      Best Regards,
