Subject: Re: [xsl] Processing IDREFS attributes From: JBryant@xxxxxxxxx Date: Tue, 1 Nov 2005 16:10:51 -0600 |
Well, I think the folks who wrote the specs thought you'd pass one IDREF at a time, rather than bunches of them. Also, I come from the school that keeps each function as atomic as possible, so I'd rather have tokenize and id be separate functions, since I'll undoubtedly use tokenize outside of id someday.

I'm slowly building a list of reasons to move on to XLST 2, just lazy at the moment I guess ;-) ..dan At 01:46 PM 11/1/2005, you wrote: >Hi, Dan, > >Assuming that "Location", "Party", and "Organization" are three different >locations in your source file, you'll need either a recursive template (if >you use XSLT 1.0) or the tokenize function (if you use XSLT 2.0). > >If you do need a recursive template, it's a pretty simple one in this >case: > ><xsl:template name="process-ids"> > <xsl:param name="in-string"/> > <xsl:choose> > <xsl:when test="contains($in-string, ' ')"> > <!-- process an id here; substring-before($in-string, ' ') gets the >id string to process--> > <xsl:call-template name="process-ids"> > <xsl:with-param name="in-string" >select="substring-after($in-string, ' ')"/> > <xsl:call-template> > </xsl:when> > <xsl:otherwise> > <!-- process the last id here --> > <xsl:otherwise> > </xsl:choose> ></xsl:template> > >You'd call it with > ><xsl:call-template name="process-ids"> > <xsl:with-param name="in-string" select="@parameters"/> ></xsl:call-template> > >The XSLT 2.0 tokenize function is much less verbose: > ><xsl:for-each select="tokenize(@references, ' ')"> > <!-- process each id here; . gets the id string --> ></xsl:for-each> > >That's one of the reasons I like XSLT 2.0. > >Jay Bryant >Bryant Communication Services >(presently consulting at Synergistic Solution Technologies) > > > > >Dan Vint <dvint@xxxxxxxxx> >11/01/2005 03:00 PM >Please respond to >xsl-list@xxxxxxxxxxxxxxxxxxxxxx > > >To >xsl-list@xxxxxxxxxxxxxxxxxxxxxx >cc > >Subject >[xsl] Processing IDREFS attributes > > > > > > >I've got a few places where I have an attribute of type IDREFS and a >sequence of ID values like references="Location Party Organization".
