在Python xml.dom中读取字符串而不进行解析

Question

As you probably know, Pythons xml.dom readString() throws an exception, if there is anything wrong with the xml code.

I am currently writing a simple xmpp chat server, and as you probably also know, one of the first client request message does not close the stream:stream tag, until it does not get a reply.

Is there any way to use pythons xml.dom without "parsing" the xmlcode or should I write my own xml parser?

Answer 1

DOM parsers always need to read the entire XML file. You want a SAX parser .

Answer 2

Any reason you're not using an already established XMPP library like xmpppy ? ( See also )

Answer 3

The parser that is likely to give you the best experience is xml.parsers.expat . In your StartElementHandler create a DOM element, and add it to the current element as a child, then set the current element to the new element. In your EndElementHandler , pop the current element to that element's parent. If the parent was null , you have a stanza. Do careful testing of namespaces; you're liable to get the attributes wrong the first time.
