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

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.
