xpath 2.0 query - how to test for the first occurence of an element in a xml document
- by Mike
I have the following xsl template:
<xsl:template match="para">
<fo:block xsl:use-attribute-sets="paragraph.para">
<!-- if first para in document -->
<!--<xsl:if test="//para[1] intersect .">-->
<xsl:if test="//para[1] intersect .">
<xsl:attribute name="space-after">10pt</xsl:attribute>
<xsl:attribute name="background-color">yellow</xsl:attribute>
</xsl:if>
<xsl:choose>
<xsl:when test="preceding-sibling::*[1][self::title]">
<xsl:attribute name="text-indent">0em</xsl:attribute>
</xsl:when>
<xsl:when test="parent::item">
<xsl:attribute name="text-indent">0em</xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:attribute name="text-indent">1em</xsl:attribute>
</xsl:otherwise>
</xsl:choose>
<xsl:apply-templates/>
</fo:block>
</xsl:template>
The problem I am having is selecting the very first para node in the document from the following xml:
<document>
<section>
<paragraph>
<para>Para Text 1*#</para>
<para>Para Text 2</para>
</paragraph>
</section>
<paragraph>
<para>Para Text 3*</para>
<para>Para Text 4</para>
<para>Para Text 5</para>
<sub-paragraph>
<para>Para Text 6*</para>
<para>Para Text 7</para>
</sub-paragraph>
</paragraph>
<appendix>
<paragraph>
<para>Para Text 8*</para>
</paragraph>
<paragraph>
<para>Para Text 9</para>
</paragraph>
</appendix>
</document>
the xpath I am currently using is "//para[1] intersect ." which is selecting the first para for each group of para (denoted with a * in XML sample). Any ideas on how I can just select the first occurance of para within document (denoted with a #)?
