Re: RE: [xml] clarification about "empty" text nodes

[<oliverst online de>]

err, no.

Look at this example:

<Node>
    <Node1>Value</Node1>
<Node>

If I take the pointer to "Node" and do a xmlNodeGetContent() on it, I
get formatting stuff for the whole underlying tree. Same witha pointer
to "Node1" gives me "Value" as result. The problem is, that I can't
determinate it by the type as "Node" is type 1 (XML_ELEMENT_NODE) and it
has a child with the name "text" of type 3 (XML_TEXT_NODE) and it
contains the formatting stuff. "Node1" is the same type and has the same
type as child with the name "text" and it contains "Value". By simple
type-checking it doesn't work.

"Node"(XML_ELEMENT_NODE)
-> childs 
"text"(XML_TEXT_NODE)
"Node1"(XML_ELEMENT_NODE)
xmlNodeGetContent() result -> formatting chars for underlying tree
(always beginning with 0x0a???)

Node1(XML_ELEMENT_NODE)
->childs
"text"(XML_TEXT_NODE)
xmlNodeGetContent() result -> "Value"
