用python把xml和xsl转换为html

前些天用python处理xml的转换的一个小程序，用来把xml,xsl转换成html。

用的libxml2，所以还要先安装了libxml2模块才能使用。

# -*- coding: mbcs -*-
#!/usr/bin/python

import libxml2, libxslt

class compoundXML:
    def __init__(self):
        self._result = None
        self._xsl = None
        self._xml = None
       
       
    def do(self, xml_file_name, xsl_file_name):       
        self._xml = libxml2.parseFile(xml_file_name)
        if self._xml == None:
            return 0
        styledoc = libxml2.parseFile(xsl_file_name)
        if styledoc == None:
            return 0
        self._xsl = libxslt.parseStylesheetDoc(styledoc)
        if self._xsl == None:
            return 0

        self._result = self._xsl.applyStylesheet(self._xml, None)               
       
    def get_xml_doc(self):
        return self._result           
       
       
    def get_translated(self):
        return self._result.serialize('UTF-8')       
   
    def save_translated(self, file_name):
        self._xsl.saveResultToFilename(file_name, self._result, 0)
       
    def release(self):
        '''
        this function must be called in the end.
        '''
        self._xsl.freeStylesheet()
        self._xml.freeDoc()
        self._result.freeDoc()
        self._xsl = None
        self._xml = None
        self._result = None
       
       

if __name__ == '__main__':
    test = compoundXML()
    test.do('test/testxmlutil.xml', 'test/testxmlutil.xsl')
    print test.get_translated()
    test.save_translated('test/testxmlutil.htm')
    test.release()
