StringRegExp reading from end

[kiboost]

I have some string to get into a large xml file. I begin with regexp, but need some regexp reading from right to left.

I want to find this '<Name>(.*?)</Name><GroupLevel>-1</GroupLevel><DynamicValues>'

My problem is there tons of <Name>xxx</Name> tags before the one I want, which is followed by '<GroupLevel>-1</GroupLevel><DynamicValues>'

So, is there a way to make sre read for the right to left, so it find the name tag just before the grouplevel etc, and not a string for first name tag in the file ?

Mmm, I think there is. Although that part of RE's is still clouded by fog to me.

To prep for potential example codes in relation to this you could start taking a peek at the following RE site. http://www.regular-expressions.info/

I don't see your point. With a pattern like the one you shown, the match only returns the last one:

Pattern '<Name>(.+?)</Name>\s*<GroupLevel>-1</GroupLevel><DynamicValues>'

Input:

<Name>abc</Name>

<Name>abcd</Name>

<Name>abcde</Name>

<Name>abcdef</Name>

<Name>abcdefg</Name>

<Name>abcdefgh</Name><GroupLevel>-1</GroupLevel><DynamicValues>

Match: 'abcdefgh'

Beware that a large number of sites generate dynamic html from several servers, not all of them behaving always identically, specially whitespace(s) (RE \s) may be appear or disappear at almost any point in the html content. I know of several sites that will deliver distinct whitespacing, even across page refresh within seconds. This can be problematic when applying a regexp on the source.

Thks all, these regexp are not easy lol

I've solved my problem with some stringsplit/stringreplace.
