How can I get the contents of a CDATA section?

[Mihai Matei <mi...@yahoo.com>]

Hi,

sample file:

<?xml version="1.0" encoding="UTF-8"?>
<test>
    <SupplementalAction>
        <![CDATA[#!/usr/bin/ksh
                            other stuff
    ]]>
</SupplementalAction>
</test>

sample code that does not work:

    DOMNode *temp = pDoc->getElementsByTagName(X("SupplementalAction"))->item(0);
    const XMLCh* contents = temp->getFirstChild()->getNodeValue();
    char* strValue = XMLString::transcode(contents);
    std::cout << "\nCDATA:" <<strValue;

What am I doing wrong? Any help appreciated.

Is there any way of printing the in-memory DOM structure?

Thanks.

First you need to understand what goes in the DOM.  In your example, the
first child of the SupplementalAction element is a text node containing
whitespace.  Then comes the character data, then more whitespace.   If
all you're interested is the contents of the CDATA section, traverse the
list of children using DOMNode::getFirstChild() and
DOMNode::getNextSibling().  Use DOMNode::getNodeType() to check the type
of each node, and when you find one whose type is
DOMNode::CDATA_SECTION_NODE, cast it to DOMCharacterData and call
DOMCharacterData::getData().  (I'm not 100% certain of that last step,
not having done that bit myself.)

Alternately, DOMNode::getTextContent() might serve your purposes.
