Python validating sax parser

will manage to build the source distribution as long as libxml2 and libxslt are properly installed, including development packages, i.e. See the requirements section above and use your system package management tool to look for packages like in the source tree).

Building from developer sources or from modified distribution sources requires Cython to translate the lxml sources into C code.

Start by creating a class that extends Default Handler: method that uses the the create XMLReader method from the XMLReader Factory class to choose a SAX driver dynamically. Default Handler; public class My SAXApp extends Default Handler You can compile this code and run it (make sure you specify the SAX driver class in the sax.driver property), but nothing much will happen unless the document contains malformed XML, because you have not yet set up your application to handle SAX events.The source distribution ships with pre-generated C source files, so you do not need Cython installed to build from release sources.If you have read these instructions and still cannot manage to install lxml, you can check the archives of the mailing list to see if your problem is known or otherwise send a mail to the list.When a Sax parser parses a XML document and every time it encounters a tag it calls the corresponding tag handler methods when it encounter a Start Tag it calls this method public void start Element(String name, Attribute List attrs) when it encounter a End Tag it calls this method public void end Element(String name) This program also parses a XML file and prints it on the console . In this example, the Print Using Sax Class extends the Handler Base class and implemets the call back methods to handle the printing The steps involved are Get a instance of SAX parser, The previous program illustrated how to Parse an existing XML file using both SAX and DOM Parsers.But generating a XML file from scratch is a different story , for instance you might like to generate a xml file for the data extracted form the database.
