[libxml++] [Patch] problem with TextReader.read()

[raoul <rao...@gm...>]

Hi there,

I'm working with TextReader, and I had some trouble wen playing with 
exceptions. In fact it was a problem in read() function.

Here is the thing, when doing:

    xmlpp::TextReader reader("example.xml");

    while(reader.read())
    {
[...]
    }

and if the xml file has a parse error, it just fall in an infinite loop 
because read() always read the same node.
In fact, according to the xmlTextReaderRead() doc, this function can return -1 
if an error occured, and not just a boolean value.
Attached is a patch to make this work and also throw an exception.
