Specific template for the first element
I have a template:
<xsl:template match="paragraph">
...
</xsl:template>
I call it:
<xsl:apply-templates select="paragraph"/>
For the first element I need to do:
<xsl:template match="paragraph[1]">
...
<xsl:apply-templates select开发者_开发知识库="."/><!-- I understand that this does not work -->
...
</xsl:template>
How to call <xsl:apply-templates select="paragraph"/>
(for the first element paragraph
) from the template <xsl:template match="paragraph[1]">
?
So far that I have something like a loop.
I solve this problem so (but I do not like it):
<xsl:for-each select="paragraph">
<xsl:choose>
<xsl:when test="position() = 1">
...
<xsl:apply-templates select="."/>
...
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
One way to do this could be to make use of a named template, and have both the first and other paragraphs calling this named template.
<xsl:template match="Paragraph[1]">
<!-- First Paragraph -->
<xsl:call-template name="Paragraph"/>
</xsl:template>
<xsl:template match="Paragraph">
<xsl:call-template name="Paragraph"/>
</xsl:template>
<xsl:template name="Paragraph">
<xsl:value-of select="."/>
</xsl:template>
Another way, is to call apply-templates separately for the first paragraph and other paragraphs
<!-- First Paragraph -->
<xsl:apply-templates select="Paragraph[1]"/>
<!-- Other Paragraphs -->
<xsl:apply-templates select="Paragraph[position() != 1]"/>
Name your generic paragraph
template, then invoke it by name from the paragraph[1]
template:
<xsl:template match="paragraph" name="paragraph-common">
...
</xsl:template>
<xsl:template match="paragraph[1]">
...
<xsl:call-template name="paragraph-common"/>
...
</xsl:template>
A template can have both a match
and a name
attribute. If you set both, you can invoke the template both by xsl:apply-templates
and by xsl:call-template
.
