Re: efficiently extracting a capture group from analy

Hi everyone!

Given some filename string like

B <xsl:variable name="file" select="'path/my-sometype.xml'"/>

Ibd like to extract the bmy-(\w+)b part of the filename using analyze-string(). So far I have

B <xsl:variable name="my-file-type" select="data(analyze-string($file, 'my-(\w+)')//fn:group[1])"/>

which works by extracting the <group> descendant from the <analyze-string-result> tree, then converting it to text. Is there a more concise way to do this?

I had to define

B xmlns:fn=http://www.w3.org/2005/xpath-functions <http://www.w3.org/2005/xpath-functions>

in my stylesheet for fn:group to match, and Ibm not sure if therebs a better way to do that too.

Thanks!
