This is a good place to start... http://www.roblocher.com/technotes/regexp.aspx good luck -----Original Message----- From: Rashmi Rubdi [mailto:rashmi.sub@xxxxxxxxx] Sent: Saturday, April 21, 2007 1:51 PM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] Regular Expressions in XPath 2.0 I guess XPath is not off-topic to this list, if it is then I'm sorry about this post. I have just started learning the 2.0 versions of XSLT and XPath and recently learned that Regular Expressions were introduced in XPath 2.0 and were not in XPath1.0. I would like understand a few things about the Regular Expressions in XPath 2.0. According to the slide here: http://www.mulberrytech.com/papers/XPath-2-0-User-Grp-HTML/slide060.html the regular expressions in XPath are taken from Perl. I've studied Regular Expressions in school a long time ago, but I've never learned Perl. I have a few questions 1) Are regular expressions in XPath 2.0 identical or are they similar to those in Perl? 2) What would be the best approach to re-learn Regular Expressions with respect to XPath 2.0, I know I have to first re-learn the basics of regular expressions too. I think there's a standard for Regular Expressions and each programming language specializes or deviates from the standard. Thank you for your input. -Rashmi
