Here is an example of a xml node I am trying to parse: 

<thisNode>  </thisNode>


I am using xmlTextReaderConstValue to read the value of thisNode. The
problem is that if the node is made of only 1 or more spaces only, this
function returns a NULL. My question is, is there another function that


paphio:~/XML -> cat tst.xml

Value returned is $1 = (const xmlChar *) 0x87363f4 "  "

  on the second node, the #text one, the value returned is the text content
not NULL. I.e. libxml2 operates as expected.
