Actually I was the one who very recently ran into an issue with XML with
namespaces coming from a 3rd party that did not seem to be handled
properly by Witango and xerces. I'll see If I can reproduce the problem
again, and send a specific code example. It became a moot point for me
because I decided to just use some xslt to remove all the namespace
references to make subsequent xslt stylesheets a bit easier to read and
write.
It's possible I was doing something wrong, but I could swear that I
ended up installing the latest version of xerces and ran a command
manually outside of Witango and the xsl transform worked just fine.
Which made me assume there was a problem with Witango (or one of it's
3rd party libraries)

Most of the examples, were from people who emailed me, to use my
javaxmlcleaner to strip namespaces before parsing in witango. I will
try to find a specific example, but I know there were a few on the
list. They would not parse in witango dom, but java xml parsed them
fine, and my RB xml classes also did.
As you know, I try to send you what you need each time I find a bug
myself, whether or not you respond to me. But the examples I saw that
did this, were forwarded from others. But I think I found one myself
not to long ago. I will look for it.

Robert please send me your xml code that does not work and we can
then investigate the issue.

Thats true, but sometimes, the dom blows up just trying to parse xml
with namespaces, so you can't even use xpath, without stripping
namespace before loading in witango as a dom.
So, I think it would true to say the Witango DOM does not always
like namespaces.

Actually Ben the DOM and XPath implementations are the Xerces
library from the Apache project. Last time I looked it implemented
namespaces quite well. All you need to do is learn and understand
how to write xpath expressions correctly. It is a little more
complex than XPointer. Namespace example below.
<@ASSIGN request$testDOM "<@DOM VALUE='<?xml version="1.0"

im not quite sure why this is. It could be the :
I have had to strip the name spaces prior to DOM'ing the results
from @URL.
This could be a simple Search and Replace of the : to _ or just
simply
change the : to a "" taking "Soapenv:Envelope" to " SoapenvEnvelope "
Try removing the : and using the new name created.

Neither of those work either...
Should I strip out certain parts of the results first?

Looks like XPATH has an issue with name spaces.
Have you tried:
<@elementvalue object=local$packageDOM
XPATH="/soapenv:Envelope/soapenv:Body/AddPartnerMessageResponse/Timestamp">
or
<@elementvalue object=local$packageDOM XPATH="/
Envelope/soapenv/AddPartnerMessageResponse/Timestamp">
To force xpath to that level

Subject: Re: Witango-Talk: Parsing DOM Response for element by name
I'm stumped on this, can anyone see what I'm doing wrong?
I make a URL call and receive XML results. I'm trying to use
XPATH as
described below, but get no results.
The XML returned looks like this:
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<soapenv:Body>
<AddPartnerMessageResponse
xmlns="urn:ebay:apis:eBLBaseComponents">
<Timestamp>2006-04-25T21:37:53.484Z</Timestamp>
<Ack>Success</Ack>
<Version>461</Version>
<Build>e461_core_Unified_2718252_R1</Build>
<MessageID>2702</MessageID>
<MessageID>2703</MessageID>
</AddPartnerMessageResponse>
</soapenv:Body>
</soapenv:Envelope>
This command:
<@elementvalue object=local$packageDOM
XPOINTER="root().child(1).child(1).child(1)">
Returns 2006-04-25T22:10:32.234Z
But
<@elementvalue object=local$packageDOM XPATH="//Timestamp">
Doesn't return anything
Any ideas?

Dave,
XPATH="//Timestamp"
would do the trick.
XPath is a lot nicer to use than XPointer.
This of course assumes that you're using a version of Witango that
supports XPath. If not, it's time to upgrade.
You may run into issues with namespaces. It might be easier for
you to
clean out all namespace references before traversing the DOM.

I'm trying to parse a DOM reponse from a web service. I'm
looking to
find a
particular element in the reponse. I know the name of the
element I
need,
but I won't always know it's position in the response.
For example, I receive the following response:
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<soapenv:Body>
<GeteBayOfficialTimeResponse

<Ack>Success</Ack>
<Version>461</Version>
<Build>e461_core_Unified_2718252_R1</Build>
</GeteBayOfficialTimeResponse>
</soapenv:Body>
</soapenv:Envelope>
And I need the <timestamp> element. I can access it by doing
this:
<@elementvalue object="local$packageDOM"
element="root().child(1).child(1).child(1)">
But I'd like to be able to reference <timestamp> instead of
having to
know
the root/child relationships.
Is there an easy way to do this?
