libxml2 HTML parsing
I'm parsing HTML with libxml2, using XPath to find elements. Once I found the element I'm looking for, how can I get the HTML as a string from that element (keeping in mind that this element will have many child elements). Given a document:
<html>
开发者_C百科 <header>
<title>Some document</title>
</header
<body>
<p id="faq">
Some kind of text <a href="http://www.nowhere.com/">here</a>.
</p>
</body>
</html>
Say I retrieved the body element with XPath and then get the HTML for that, I'd like to end up with a string containing:
<body>
<p id="faq">
Some kind of text <a href="http://www.nowhere.com/">here</a>.
</p>
</body>
How can I do this?
That is the purpose of xmlNodeDump:
EDIT:
When you have a xmlNodePtr node, do something like:
xmlBufferPtr nodeBuffer = xmlBufferCreate();
xmlNodeDump(nodeBuffer, doc, node, 0, 1);
// ... Do something with nodeBuffer->content
// When done:
xmlBufferFree(nodeBuffer);
The 4th and 5th parameters control indentation and formatting.
