Python实现把xml或xsl转换为html格式

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()
