Re: [xml] Root node attributes

the simpliest solution I've found on my own is like that:

xml = xmlReaderForFile("example.xml", NULL, 0);
doc = xmlTextReaderCurrentDoc(xml);
root = xmlDocGetRootElement(doc);
agent = xmlGetProp(root, "agent");

and then proceed with the rest of parsing using the Reader interface, as
Do not forget to use xmlFreeDoc(doc) at the end of parsing.

  Well that's not 100% guaranteed to work, the xmlTextReaderRead()
will scan through all nodes. If there is another node (not element)
before the root node, like say a comment, you code will break.
  do Read() until you reach an element and use the reader
to get the attribute.

Hello guys,

I'm just wondering if is there a simple way in LibXML2 to get an
attribute value from the root node, preferably using the Reader interface.
I have no problems at all with attributes from other nodes, they all are accessible by
xmlTextReaderGetAttribute function, but root.
Apparently LibXML2 discards root node attributes, or may be I'm missing something.

Just to be clear, I intend to parse something like:

<?xml version="1.0" encoding="UTF-8"?>
<Example agent="myclient">

and I'd like to get the value of the "agent" attribute.
Can someone give me an hint?
