[XML-SIG] SAX_expat extension -- parseString()

[Paul Schreiber]

I hacked up my copy of drv_pyexpat.py because I wanted to be able to
parse XML that didn't exist in files or URLs.

Here's the code:

class SAX_expat(saxlib.Parser,saxlib.Locator):
    "SAX driver for the Pyexpat C module."
    
    [snip]

    def parse(self,sysID):
        self.sysID=sysID
        self.parseString(urllib.urlopen(sysID).read())

    def parseFile(self,fileobj):
        self.parseString(fileobj.read())

    def parseString(self, str):
        self.reset()
        self.doc_handler.startDocument()

        if not self.parser.Parse( str, 1):
            self.__report_error()

        self.doc_handler.endDocument()
