Python是不要再追XMLSyntaxError

Question

我有以下蟒蛇+ LXML代碼：

def doXMLValidation (xml_file, schema_file): 
    '''Validates xml file against schema''' 
    s_doc = etree.parse (schema_file) 
    schema = etree.XMLSchema (s_doc) 
    x_file = etree.parse(xml_file) 

    try: 
     schema.assertValid(x_file) 
    except etree.XMLSyntaxError as e: 
     print (_formatXMLError(e)) 
     return False 
    except etree.DocumentInvalid as e: 
     print (_formatXMLError(e)) 
     return False 
    except: 
     print ('Something strange...') 
     return False 
    else: 
     return True 

當我試圖用一個破損的XML/FB2文件（標籤移除）我期望能獲得適當XMLSyntaxError例外測試處理。然而，相反，我得到與該錯誤崩潰：

../.metadata/.plugins/org.python.pydev.debug/.coverage Traceback (most recent call last):
File "../.eclipse/org.eclipse.platform_3.5.0_155965261/plugins/org.python.pydev.debug_1.5.9.2010063001/pysrc/coverage.py", line 1029, in the_coverage.command_line(sys.argv[1:]) File "../.eclipse/org.eclipse.platform_3.5.0_155965261/plugins/org.python.pydev.debug_1.5.9.2010063001/pysrc/coverage.py", line 405, in command_line execfile(sys.argv[0], main._dict_) File "../workspace/PythonPractice/src/lxmlValidation.py", line 58, in test() File "../workspace/PythonPractice/src/lxmlValidation.py", line 54, in test result = doXMLValidation (source, schema) File "../workspace/PythonPractice/src/lxmlValidation.py", line 31, in doXMLValidation x_file = etree.parse(xml_file) File "lxml.etree.pyx", line 2692, in lxml.etree.parse (src/lxml/lxml.etree.c:49594) File "parser.pxi", line 1500, in lxml.etree._parseDocument (src/lxml/lxml.etree.c:71364) File "parser.pxi", line 1529, in lxml.etree._parseDocumentFromURL (src/lxml/lxml.etree.c:71647) File "parser.pxi", line 1429, in lxml.etree._parseDocFromFile (src/lxml/lxml.etree.c:70742) File "parser.pxi", line 975, in lxml.etree._BaseParser._parseDocFromFile (src/lxml/lxml.etree.c:67740) File "parser.pxi", line 539, in lxml.etree._ParserContext._handleParseResultDoc (src/lxml/lxml.etree.c:63824) File "parser.pxi", line 625, in lxml.etree._handleParseResult (src/lxml/lxml.etree.c:64745) File "parser.pxi", line 565, in lxml.etree._raiseParseError (src/lxml/lxml.etree.c:64088) lxml.etree.XMLSyntaxError: Opening and ending tag mismatch: a line 7 and p, line 7, column 46

問題是什麼，如何解決它？

UPD：大聲笑，知道了，謝謝大家：在解析時

def doXMLValidation (xml_file, schema_file): 
    '''Validates xml file against schema''' 
    s_doc = etree.parse (schema_file) 
    schema = etree.XMLSchema (s_doc) 
    try: 
     x_file = etree.parse(xml_file) 
     schema.assertValid(x_file) 
    except etree.XMLSyntaxError as e: 
     print (_formatXMLError(e)) 
     return False 
    except etree.DocumentInvalid as e: 
     print (_formatXMLError(e)) 
     return False 
    except: 
     print ('Something strange...') 
     return False 
    else: 
     return True 

思想LXML會更愉快......

你沒有導致錯誤的語句之前一試。仔細看看堆棧跟蹤。
