IXMLDOMDocument::loadXML fails on what seems to be a perfectly fine xml

Hi,

I am trying to parse an XML file using DOM in VC++.

I need an element which is inside other elements.

So I am loading the file.

Calling GetElementsByTagName to get the first level elements.

Iterating through them, get to the one I need and here I am actually in
need of another GetElementsByTagName.

Of course there is no such func in IXMLDOMNode.

Therefore I am creating another IXMLDOMDocument and trying to load into
it that inner xml part of my desired node, by using IXMLDOMNode::xml
property.

I am using loadXML, of course.

And it fails, it returns -1.

While when I substitute that pNode->xml for the same xml piece I copy
and paste from my file it works fine.

I have displayed the pNode->xml and it looks fine. Well structured and
etc.

Please help!

Any ideas ? Leads ?

Thank you!

I have tried to get the error using IXMLDOMParseError.
The reason property is empty.
The error code property is 0.

Note that getElementsByTagName returns all matching elements under the
current node or within a current document no matter how deep, not just
immediate children. I'm not sure what you mean by "first level elements"
here.

.... but there is on IXMLDOMElement. You can QueryInterface from the
former to the latter.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

Hi Alexandra!
I am using loadXML, of course.

And it fails, it returns -1.


Are you sure that the passed string is UTF-16?
The "loadXML" function only works with UTF_16 strings! (see docu)
