Hi
I must be missing something simple...
I would like dynamically call templates using the value of a node attribute.
The
XML element has an attribute "type" and I would like to apply a template in
different mode depending on the value of "type".
If I first get the value of the attribute, I can apply the template in a
specific
mode:
<xsl:choose>
<xsl:when test="@type = 'vdtPTD'">
<xsl:apply-templates select="." mode="vdtPTD" />
</xsl:when>
...
</xsl:choose>
but it requires number of <xsl:when> calls.
I thought the following call should work:
<xsl:apply-templates select="." mode="@type" />
but it does not. In the result I get the values of all elements. Am I
missing something simple or can it not be done?
I have tried few options including variables like:
<xsl:variable name="one_panel" select="." />
Panel: <xsl:value-of select="$one_panel/@type" />
<xsl:apply-templates select="." mode="$one_panel/@type" />
The type of the panel is printed correctly using
<xsl:value-of select="$one_panel/@type" />
but the template in mode="$one_panel/@type" is not applied...
The sample XML and stylesheet are below. The calls are in the PANEL
template.
I am using Xalan that comes with J2EE 1.3.1
Thanks
