nested templates

Hi,

I want to nest templates in each other.

In my

Code: Select all

<xsl:template match="rdf:RDF">

I call for the template

Code: Select all

<xsl:apply-templates select="rdf:Description[namespace::[.='http://purl.org/dc/elements/1.1/']]" />
That works

But in the template

Code: Select all

<xsl:template match="rdf:Description[namespace::*[.='http://purl.org/dc/elements/1.1/']]">
I call for the template

Code: Select all

<xsl:apply-templates select="rdf:Description[namespace::*[.='http://ns.adobe.com/xap/1.0/rights/']]" />
And that doesn't works.

Full xslt file:

Code: Select all

I suggest to read a good XSLT book, see our books page on the website or at least an XSLT tutorial.

When you match on a node in a template that becomes the current node. Further XPath expressions will be executed in that context, so for example if you have

Code: Select all


<xsl:template match="x">

  <xsl:apply-templates select="y">

...
then the select="y" will match y elements inside the x element matched by the template.

Back to your example, in the first case the current node is rdf:RDF and your apply templates selects children rdf:Description elements. In the second case the current node is rdf:Description and you apply templates selecting children rdf:Description elements, and there are no such elements in your XML. You may want to go to the parent node and then select rdf:Description elements

Code: Select all


<xsl:apply-templates select="../rdf:Description[namespace::*[.='http://ns.adobe.com/xap/1.0/rights/']]" />
Best Regards,
George

I didn't realize how stupid my question was

I learned these basic things in school 3 years ago, but didn't use XML/XSLT until now. I guess I forgot some important things.

Thanks for pointing it out for me.
