Tag With Multiple namespaces in Xpath

Hi,

I'm writing an xsl transform to change data quite significantly (different schemas).

I'm having an issue with namespaces, which I have read up on but am still struggling with a certain problem. I have searched the forum for it but to no avail.

The start xml contains this code (namespaces simplified for ease...):

Code:

<s:Envelope xmlns:s="ssssss">
<s:Body>
<GetQuoteResponse xmlns="hhhhhh">
  <GetQuoteResult xmlns:a="aaaaa" xmlns:i="iiiii">
    <a:Charges>
        <a:Amount>123</a:Amount>
        <a:Name>XYZ</a:Name>
    </a:Charges>

A namespace "h" is defined in the top of the stylesheet with the value hhhhhh.

In the xsl, I have xpath to return the amount, which looks like:

Code:

<xsl:value-of select="s:Envelope/s:Body/h:GetQuoteResponse/GetQuoteResult/a:Charges/a:Amount" />

This doesn't work and I can see that it is because of the GetQuoteResult - I have tried it with namespaces a and i (e.g. a:GetQuoteResult) but these don't work either.

My question is what namespace I should be using to get the xpath to work?
The two defined namespaces are throwing me, if there was one (like the GetQuoteResponse tag) then it would make more sense.

It seems that having a namespace defined in the top of the stylesheet, and some defined within the xml being ouput, is messy so if someone could advise how to tidy these up as well that would be great.

Thanks,
Neil

GetQuoteResults has not prefix, so it is in the namespace defined with no prefix. Looking at the GetQuoteResults element it defined two namespaces, both of which have prefixes, so its not them.

Going up a level you see the parent element defines the 'hhhhh' namespace with no prefix, therefore the GetQuoteResults is in that namespace.

If in your XSLT you have defined the 'h' prefix for the 'hhhhh' namespace then h:GetQuoteResults is what you need.

Thanks Sam, that's made it a lot clearer - I added the previous tag namespace (h:) as you suggested and this works fine now.

Thanks again,
