Liam gave this wicked cool way to return the portion of a string that

replace($input, '^.*(\d+).*$', '$1')



However, I did some testing, and it's not returning the desired results:



<xsl:variable name="TEXT" select="'The person put 12 dollars into the

<xsl:variable name="INTEGER" select="'[0-9]+'"/>

<xsl:value-of select="replace($TEXT,'^.*(' || $INTEGER || ').*$', '$1')"/>



Result: 2 <-- should be 12



Another test:



<xsl:variable name="TEXT" select="'SATSET'"/>

<xsl:variable name="VOWELS" select="'A|E|I|O|U'"/>

<xsl:value-of select="replace($TEXT,'^.*(' || $VOWELS || ').*$', '$1')"/>



Result: E <-- should be A



What am I doing wrong?

I guess you need non-greedy matching for the .* with .*? e.g.
replace($TEXT,'^.*?(' || $INTEGER || ').*$', '$1')
