RE: [xsl] xsl:sort not working within xsl:choose

You are doing exactly what the error message says: you are using xsl:sort in a place where it may not be used. Within xsl:for-each, it must be the first child of the xsl:for-each. Try using two sort keys: <xsl:for-each select="codes/value[code_type = $code_type]"> <xsl:sort select="*[name()=$select_sort_field]" /> <xsl:sort select="code" /> Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: Hardy Merrill [mailto:HMerrill@xxxxxxxxxxxxxxxx] > Sent: 10 December 2004 13:55 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] xsl:sort not working within xsl:choose > > MSXML4 > > I'm passing a script parameter into the xsl style sheet that tells me > what the sort field should be: > > <xsl:param name="select_sort_field"/> > > and then, within my for-each loop, I have the code to decide what to > sort by: > > <xsl:for-each select="codes/value[code_type = $code_type]"> > > <xsl:choose> > <xsl:when test="$select_sort_field"> > <xsl:sort select="*[name()=$select_sort_field]" /> > </xsl:when> > <xsl:otherwise> > <xsl:sort select="code" /> > </xsl:otherwise> > </xsl:choose> > > <!-- <xsl:sort select="code" /> --> > <!-- <xsl:sort select="*[name()=$select_sort_field]" /> --> > > ----------------------------------- > > but that's not working - I keep getting this error: > > msxml4.dll error '80004005' > > Keyword xsl:sort may not be used here. > > ------------------------------------ > > What am I doing wrong?
