Parsing XML content

[Mike [MCP VB]]

Hi, I hope this is the right place to ask.

I have an xml file thus:

<?xml version="1.0" encoding="UTF-8"?>
<Message xmlns="urn:myurl-org:ns2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:myurl-org:ns2
...\Schemas\schema.xsd" type="Message">
<id root="7DC0FFE7-1224-4598-8F20-3B7662D416A1"/>
<creationTime value="2004"/>
<acknowledgement typeCode="AE">
<messageRef>
<id root="04074443-DE90-4FE8-9D4A-DBF9A7E81FFA"/>
</messageRef>
</acknowledgement>
</Message>

I wish to be able to parse the file such that I can return the root
attribute of the id node within messageRef.

Unfortunately, I cannot do this using msxml. getElementByTagName doesn't
work because a default namespace is provided. In fact, I cannot loop through
the nodes either, as msxml only suggests the document has one node <Message
/>, but no children.

I am considering swapping over from VB6 to VB.NET to accomplish this task,
as I've heard the system.xml namespace contains a revised implementation of
the DOM object that will allow use of getElementByTagName with default
namespaces.

Could anyone proffer the code to return the above attribute (as string, or
ixmlattributenode)?

Many thanks in advance.

Mike

Did you really intend to use this as an xml file? If not please post
complete xml file....but you probably should find a more on topic group.

Cheers Scorpion,

There are more elements, but they aren't pertinent to this particular issue.
The validation fell over on the scoped namespace: "urn:myurl-org:ns", such
that multiple : characters are not allowed in this namespace.

Any ideas how to parse >ANY< xml file with the above default namespace
present in it? VB, VB.NET are fine. MSXML just won't have any of it...

Thanks!

It should be possible to use selectSingleNode/selectNodes with MSXML 3,
4, and 5, you just need to make sure that a namespace prefix is
associated with that default namespace e.g.
xmlDocument.setProperty "SelectionLanguage", "XPath"
xmlDocument.setProperty "SelectionNamespaces",
"xmlns:myorg='urn:myurl-org:ns2'"
then you can use that prefix e.g.
xmlDocument.selectSingleNode("/myorg:Message")

Cheers Martin. The problem was my .setProperty "SelectionNamespaces" line,
as I was not surrounding my namespace with single quotes, and therefore
msxml thought I was attempting to declare a default scoped namespace, which
apparantly - is a big no-no.

It now works regardless of the "SelectionLanguage" property... what's this
used for? Complex XPath?

However, XPath won't work in DOMDocument50.... but will in DOMDocument...
wonder why...?
