RE: Grouping by a piece of a date
Steve, Thanks for the prompt reply - the idea is great (I didn't know I could use a function in the 'using' param - actually I am [obviously] weak in the xsl:key arena) except that: <xsl:key name="foo" match="/xml/rs:data/z:row" using="substring-before(@dCreated,'T')"/> And using the Muenchian method for grouping: <xsl:for-each select="/xml/z:row/@dCreated[generate-id(.)=generate-id(key('CreatedDates',. ))]" > <xsl:value-of select="." /> </xsl:for-each> produces no output. Am I still missing something or is this just not possible with the July MSXML release? Again - appreciation in advance, Jeffrey J. Saylor PS weird to cite the name for something when it is named for the party I'm typing to - should I have referred to it as "your" method? :) -----Original Message----- From: Steve Muench [mailto:smuench@xxxxxxxxxxxxx] Sent: Wednesday, September 06, 2000 10:42 AM To: xsl-list@xxxxxxxxxxxxxxxx Subject: Re: Grouping by a piece of a date | given xml with date attributes, I want to be able to group them by day. | Using the Muenchian method I can group by the entire value, but I can't | figure out how to group by only a piece of it.
