Find words stuck to a bracket or parenthesis but skip those in the CSS and meta tags

@dr-ramaanand said in Find words stuck to a bracket or parenthesis but skip those in the CSS and meta tags:

(<style[\S\s]*?</style>)(*SKIP)(F)|(<script[\S\s]?</script>)(*SKIP)(*F)|

does not seem to skip what is between <style............ and <\/style>) and what is between <script............ and <\/script>)

First of all, this seems like a really obvious use case for an XML parser and not regular expressions (even more so than other examples where people are trying to parse XML with regex). Just parse the XML, recursively search the elements, and extract words in a bracket or parenthesis only if the tag name is not CSS or meta. Yes, I know you’re not going to listen to me because nobody ever listens to me when I give this recommendation, but I’m going to keep banging my head against that wall because I know I’m right.

I’m not going to try to analyze your regexes because they’re godawful unhinged enormous monstrosities that should really be making you reconsider your life choices, but I have a more meta question for you: is there any particular reason why you’re doing x(*SKIP)(*F)|y(*SKIP)(*F)|z(*SKIP)(*F)|a instead of the more concise (?:x|y|z)(*SKIP)(*F)|a ?

@Mark-Olson Sorry, there is nothing in common to club either the first string or the last string

@Mark-Olson The regular expression (?:<html[\S\s]*?<\/h1>|<p[^>]*>[\S\s]*?uses\]<\/p>|<[\S\s]*?>|<style[^<>]*>[\S\s]*?<\/style>|<script[^<>]*>[\S\s]*?<\/script>)(*SKIP)(*F)|\w+\( also finds 21 matches, without skipping what is between <style......> and </style> and <script......> and </script> in the block for testing typed at the top

@Mark-Olson (?:<html[\S\s]*?<\/h1>|<p[^>]*>[\S\s]*?uses\]<\/p>|<[\S\s]*?>|style[^>]*>[^<>][\S\s]*<\/style>|script[^>]*>[^<>][\S\s]*<\/script>)(*SKIP)(*F)|\w+\( skips what is between <style......> and </style> but not what is between <script......> and </script> - can you tweak that regular expression to skip what comes between <script......> and </script> ?

Look, please stop mentioning me. I am unfollowing this post because it’s cognitively draining just reading it. I’m done trying to help you with regular expressions. You are trying to use a hammer (regular expressions) to solve a problem that requires a screwdriver (XML). XML is a recursive data structure or context free language (for example, a div can contain a div, which can contain another div, and on and on and on…), and regular expressions are not suitable for such languages. Technically Notepad++'s Boost regex flavor can be used to handle such languages, but making a Notepad++ regex that properly handles all the subtleties of XML would make you cry tears of blood.

You are going to have a miserable time working with XML (and its little brother, HTML) until you learn how to use a real scripting language like Python. This is your final warning. I’m not trying to punish you, just trying to preserve my own sanity.

This RegEx (?:<html[\S\s]*?<\/h1>|<p[^>]*>[\S\s]*?uses\]<\/p>|<[\S\s]*?>|style[^>]*>[^<>][\S\s]*<\/script>)(*SKIP)(*F)|\w+\( seems fine. It finds every word stuck to a simple/round bracket or parenthesis to its right but skips what comes between the <html........</h1>, <p...... uses]</p>, <.........>, as well as style.......... </script>

Sorry, the Regular expression (?:<html[\S\s]*?<\/h1>|<p[^>]*>[\S\s]*?uses\]<\/p>|<[\S\s]*?>|style[^>]*>[^<>][\S\s]*<\/script>)(*SKIP)(*F)|\w+\( finds every word stuck to a simple/round bracket or parenthesis to its right but skips what comes between the <html........ and </h1>, <p...... and uses]</p>, <......... and >, as well as style.......... and </script>

On using the above RegEx, in 80 files out of 300 files in a folder, the whole text of the file was selected, instead of just a word stuck to a simple, round bracket/parenthesis to its right. Is it because no such words were found in the file (only 2 such words were found in two different files)?
