Find Everything Between Two Xml Tags With Regex

Find everything between two XML tags with RegEx

It is not a good idea to use regex for HTML/XML parsing...

However, if you want to do it anyway, search for regex pattern

<primaryAddress>[\s\S]*?<\/primaryAddress>

and replace it with empty string...

Regex for python to capture everything between two XML tags

I believe you missed scaping the backslash and accounting for eventual multi-lines. The result should look like this:

<rpc-reply.*?>((.|\n)*?)<\/rpc-reply>

P.S.: One might also look into XML parsing modules (like ElementTree) depending on the use case.

Regex to extract specific XML tags and name them in XML file

I think your switch is perfectly fine and, if you wanted to match 2 different lines with one regex pattern, as far as I can tell, it would require to load all the file in memory and I don't think that's a route you want to take considering it's size is 60Gb+. You could add a new condition to your switch statement where it would break the loop if both variables have been populated so you don't need to keep looping until EOF:

switch -Regex -File $inputxml {

{ $currentFCF -and $currentDKY } { break }

'<FCF>(?<key1>[-]?\d+)</FCF>' {
$currentFCF = $matches.Key1
continue
}

'<DKY>(?<key2>.*)</DKY>' {
$currentDKY = $matches.Key2
continue
}
}

RegEx find all XML tags

You could change (?<=<)(.*?)((?= \/>)|(?=>)) to (?<=<)([^\/]*?)((?= \/>)|(?=>)), i.e. instead of using (.*?) for the tag name, use ([^\/]*?). / is not allowed in tag names anyway.

How to delete all characters and lines between two XML tags

Use Regular expressions and . matches a newline

Using Regex to extract a specific xml tag

As posted in the comments, this regex does the trick :

(?<=<tpcs>).*?(?=<\/tpcs>)

As seen in this demo.

Explanation :

  • (?<=<tpcs>) is a positive lookbehind (?<=...), it asserts that a certain string, <tpcs> is placed before the string to match.
  • .*? the dot matches any character, zero or multiple times because it's followed by a *. Finally, the ? character next to it is a lazy quantifier which means that it's gonna match until the first occurence of what's coming next.
  • (?=<\/tpcs>) is a positive lookahead (?=...), it asserts that the string follows the pattern.
