[xsl] parsing entities

[silvan <silvan@xxxxxxxxx>]

Dear List

Does anyone has an idea about how to do
dynamic calls of external entities?
In the xslfile i have a set of Entities defined
which should get included according to the parsed
xml;

<!ENTITY foo "value_foo">
<!ENTITY bar "value_bar">


the xml looks somewhat similar to;

<elem name="foo">
 <elem_foo>blah</elem_foo>
</elem>
<elem name="bar">
 <elem_bar>blah</elem_bar>
</elem>


... and now i try to fetch the appropriate
entities according to an element's name attribute


<xsl:for-each select="elem">
  <!--  &{@name}; -->
</xsl:for-each>

The above obviously won't work, just shows the
basic idea of assigning Entities depending on
a node's attribute.

Maybe there's already a mistake in understanding...
Any ideas etc. highly appreciated 


thanx
silvan
