Hi Ryan,

Your XML source document has a default namespace declaration for the
namespace "urn:oasis:names:tc:SAML:1.0:protocol", which means that any
elements that don't have a prefix are in this namespace. This includes
the <Status> and <StatusCode> elements in your XML document.

When you refer to an element using XPath, you must use a prefix for
all elements that are in a namespace; without a prefix, the element
name refers to an element in *no* namespace. For example, your:

  <xsl:apply-templates select="samlp:response/Status"/>

refers to <Status> elements in no namespace, and therefore doesn't
select the <Status> element in your XML document, which is in the
"urn:oasis:names:tc:SAML:1.0:protocol" namespace.

Assuming that you have the prefix 'samlp' associated with the
"urn:oasis:names:tc:SAML:1.0:protocol" namespace, you should be using
the following code in your stylesheet:

<xsl:template match="/">
  ....
  <xsl:apply-templates select="samlp:Response/samlp:Status"/>
</xsl:template>
 
<xsl:template match="samlp:Status">
  <xsl:value-of select="samlp:StatusCode/@Value"/>
</xsl:template>

[Note the change of case for sampl:Response and that the second
template matches *all* samlp:Status elements, not just those that
appear within a samlp:Response element.]

Cheers,

Jeni
