Subject: Re: [xsl] Processing two documents, which order? From: Wolfgang Laun <wolfgang.laun@xxxxxxxxx> Date: Fri, 8 Apr 2011 13:46:54 +0200 |
I've been using expressions such as <xsl:variable name="prefix" select='"(^|\W)"'/> <xsl:variable name="suffix" select='"($|\W)"'/> <xsl:variable name="pattern" select="concat($prefix,$property,$suffix)"/> Notice that a) the hyphen is included in the set of stoppers, and b) that you have to handle the cases 0word$, \Wword$, ^word\W and \Wword\W separately so as to not lose a character matching the \W. I think that the hyphen can be excluded by a character class subtraction, but I'll have to study the syntax some more. -W On 8 April 2011 13:21, Dave Pawson <davep@xxxxxxxxxxxxx> wrote: > On Fri, 08 Apr 2011 11:47:18 +0100 > David Carlisle <davidc@xxxxxxxxx> wrote: > >> On 08/04/2011 11:11, Dave Pawson wrote: >> > I really couldn't contemplate writing such a regex to be honest >> > David. >> >> if you have a whitespace list of words then the regex is >> string-join(tokenize($list,'\s+'),'|') >> is that so hard to contemplate? >> or you could, as Wolfgang just commented, try to give the regex >> engine a helping hand by pre-optimizing that regex by pulling out >> common prefixes. >> >> David > > With Wolfgangs notes, I'm struggling with the regex for one. > > <xsl:analyze-string select="." > regex="[^a-z]({$property})[\s.,",'<$]"> > > Is currently missing >keyword .... > and > ... keyword<.... > > Since checking for frisbee (where bee is the keyword) > causes >bee .... to be missed. > > Ditto with the termination?
