Re: [xml] xml streaming

["Richard Jinks" <cyberthymia yahoo co uk>]

Martyn,

You should be able to use the Push parser in libxml, see
http://xmlsoft.org/library.html for an overview.
An example of its use is in xmllint.

Essentially, you set up the parser by calling xmlCreatePushParserCtxt(),
then as you get chunks of XML over the stream, feed them in to the parser
with xmlParseChunk().
The links to the API docs for these functions are:
http://xmlsoft.org/html/libxml-parser.html#XMLCREATEPUSHPARSERCTXT
http://xmlsoft.org/html/libxml-parser.html#XMLPARSECHUNK

Using this method, you don't need to receive the fully formed XML document
before parsing as it will parse the XML as it receives it, building up the
DOM tree (or calling the SAX callbacks) on the fly.
When you receive the last bit of XML from the stream, set the terminate flag
in your last call to xmlParseChunk().

Hope this helps,
Richard Jinks
