error when calling apply templates when node contains attributes

I have an xml where a node may or may not include attributes.

<A>
<Envelope>
      <Body>
            <TravelRS EchoToken="String" TimeStamp="2013-04-29T19:02:31" xmlns:xs="http://www.w3.org/2001/XMLSchema">
                  <TravelItinerary> ... </TravelItinerary>
      </Body>
</Envelope>
</A>


My xsl does an apply-template to loop through the TravelRS. However, if there are attributes included it does not go through into the code.  How can I work around that?

This is what my xsl has

<xsl:when test="Envelope/Body/TravelRS">
      <xsl:apply-templates select="Envelope/Body/TravelRS"/>
</xsl:when>

I am not really sure I understand

but are you not mixing up attributes with namespace declarations?

Is the attribute like this? xmlns="foo"
then you need to post a real piece of XML with the namespace (the attributes) in it

likely you can do this in your stylesheet
xmlns:ns1="foo"
('foo' being the namespace copied from the source)

and do
      <xsl:apply-templates select="ns1:Envelope/ns1:Body/ns1:TravelRS"/>

note that you can drop the when clause
      <xsl:apply-templates select="ns1:Envelope/ns1:Body/ns1:TravelRS"/>
will do nothing if the nodes aren't there

Gertone:

I didn't realize, but it's not the attributes that is causing the apply-templates to be skipped, but instead it's the xmlns:xs="http://www.w3.org/2001/XMLSchema" line which causes failure.

If i remove this line then success.

I have it as follows:

<TravelRS EchoToken="String" TimeStamp="2013-04-29T19:02:31"                   xmlns="http://webservices..com/XML/2001/08"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

How can i call my template while maintaining those 3 xmlns prefixes?

I am not sure about what you say...
but this line
xmlns="http://webservices..com/XML/2001/08"
puts all elements in a default namespace.
and will break te stylesheet snippet you just showed us

xmlns:xs="http://www.w3.org/2001/XMLSchema"
does not hurt unless you have a xs:prefixed-element

Can you post the entire stylesheet and an example element

Do you need the stylesheet to work for both with and without the namespaces?
If that is the case, use one of the following approaches
- use XSLT2 and put a *: in front of each element in each XPath
- make two passes, one to get rid of the namespaces in any case and then the stylesheet you already have. If this approach makes sense, I will make the first stylesheet for you

If it only needs to work in case of namespace declarations... you can hardwire the namespace as I did with the ns1:
