I've been banging my head against a brick wall for a few days now. Having
seen the level of expertise here, and given my own preliminary stumblings
in xml and xslt, I feel a little foolish trying to poach some assistance
when I really ought to be studying more, but I don't seem to be able to
find any answers. I'd be very grateful for any assistance with the
following problem:
I have the following XML: <newsbriefs> <item> <date>2001-02-08</date> <title>Newsletter No. 14</title> <category type="news"/> <jurisdiction name="All"/> <summary>The Regie des Rentes has released an English version of La Lettre No. 14, which discusses the changes brought about by Bill 102.</summary> <source> <link href="http://www.rrq.gouv.qc.ca/an/prive/lettrercr/lettre14.htm">Newsletter</link> </source> <news/> <backgrounders/> <progress> <first_reading/> <second_reading/> <third_reading/> <royal_assent/> <in_force/> </progress> <subjects> <subject_ref reference="pensions"/> <subject_ref reference="governance"/> </subjects> </item> <item> <date>2001-02-09</date> <title>Labour Force statistics</title> <category type="news"/> <jurisdiction name="All"/> <summary>Employment was virtually unchanged in January. The unemployment rate edged up 0.1 percentage points to 6.9%.</summary> <source> <link href="http://www.statcan.ca/Daily/English/010209/d010209a.htm">StatsCan Daily</link> </source> <news/> <backgrounders/> <progress> <first_reading/> <second_reading/> <third_reading/> <royal_assent/> <in_force/> </progress> <subjects> <subject_ref reference="general"/> </subjects> </item> Many of the <item>s in my file have multiple <subject_ref> tags. I'm trying (with no success) to find a way to group them by subject_ref/@reference, but with no luck. I've gone through the archives, and found reference to a solution by Steve Muench involving the use of keys. I've (very unsuccessfully) tried to make the following work: <xsl:key name="group" match="subject_ref" use="@reference"/> [...] <xsl:for-each select="//subject_ref[generate-id(.)=generate-id(key('group', @reference)[1])]"> [...] Do I have a problem because of the fact that I have more than one <subject_ref > child for many of the <subjects> nodes in my xml? I would really appreciate any pointers on how to make this work. Chris D'Iorio inRatio Inc. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
