[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: Is this a legal XPath Expression?
 Thanks for that Mike.
Basically what I am doing is trying to find unique occurrences of the
contents of cells in column 15 of an HTML table, e.g
<td>Working conditions</td>
...
<td>Living conditions</td>
...
<td>Working conditions</td>
...
<td>Industrial relations</td>
...
<td>Living conditions</td>
...
, then, for each of these, pick out unique occurrences of the contents of
cells in column 28, and for each of those, pick out the contents of cell 3.
Looks like a job for <saxon:group>, but I couldn't figure out how to do it,
so my code looks like this: (it works, but its v. inefficient!)
<xsl:template match="TD[15]">
<!-- subject is in cell 15 -->
<xsl:variable name="subject"
select="node()[not(.=preceding::TR/TD[15]/node())]"/>
<xsl:if test="$subject !=''">
<xsl:variable name="link" select="generate-id()"/>
<tr>
<td>
<a href="{$link}.html"><xsl:value-of select="$subject"/></a>
</td>
</tr>
<!-- for each subject, output the project title to a sep. file-->
<saxon:output file="{concat($link, '.html')}">
<html><head></head>
<body><table>
<xsl:for-each select="//TR">
<xsl:apply-templates select="TD[28]">
<xsl:with-param name="subj" select="$subject"/>
</xsl:apply-templates>
</xsl:for-each>
</table>
</body>
</html>
</saxon:output>
</xsl:if>
</xsl:template>
<!-- project title is in cell 28 -->
<xsl:template match="TD[28]">
<xsl:param name="subj"/>
<xsl:if test="../TD[15]/node()=$subj">
<xsl:variable name="projecttitle"
select="node()[not(.=preceding::TR/TD[28]/node())]"/>
<xsl:if test="$projecttitle!=''">
<xsl:variable name="link" select="generate-id()"/>
<tr>
<td>
<a href="{$link}.html"><xsl:value-of select="$projecttitle"/></a>
</td>
</tr>
<!-- for each project, output the filename to a sep. file-->
<saxon:output file="{concat($link, '.html')}">
<html><head></head>
<body><table>
<xsl:for-each select="//TR">
<xsl:apply-templates select="TD[3]">
<xsl:with-param name="proj" select="$projecttitle"/>
</xsl:apply-templates>
</xsl:for-each>
</table>
</body>
</html>
</saxon:output>
</xsl:if>
</xsl:if>
</xsl:template>
<xsl:template match="TD[3]">
<xsl:param name="proj"/>
<xsl:if test="../TD[28]/node()=$proj">
<xsl:variable name="fn" select="."/>
<tr>
<td>
<a href="{$fn}">Download <xsl:value-of select="$fn"/></a>
</td>
</tr>
</xsl:if>
</xsl:template>
