Reading the value of an "xsi:type" attribute

[Carl Lindmark]

Hello all,

I'm having some problems understanding all the ins and outs with datasets
and datatables (and navigating through the filled datatable)...

Just when I thought I had gotten the hang of it, another problem arose:
I can't seem to access the "xsi:type" attribute. That is, the XML file looks
something like this:

<situation>
<objectID>123</objectId>
<situationElement xsi:type="td:roadWorksType">
...
</situationElement>
</situation>

But when I try and filter the contents of the file (after I've read all
"situation" tags into a datatable) I can't seem to access the attribute
"xsi:type" - which I need to do to distinguish between different types.

When I change the XML and write "xsi_type" instead of "xsi:type", I'm able
to access this attribute by going to the right row and write
'rowname["xsi_type"]', but the files I will have to work on use the
attribute "xsi:type" and I haven't been able to access that attribute. Can
anyone help me? Any pointers?
Thanks in advance!

Sincerely,
Carl
