Question

我正在尝试使用python和Sax解析器解析xml文件。以下部分<!DOCTYPE BMECAT SYSTEM "bmecat_new_catalog_1_2.dtd">.

有一些问题

我尝试使用DTDResolver和EntityResolver验证文件，但出现以下错误： bmecat_new_catalog_1_2.dtd：19：0：处理外部实体引用时出错

我也试图跳过！DOCTYPE，但是没有用。

删除DOCTYPE不是一个选项。

import xml.sax, csv, pandas, time 
from xml.sax.handler import EntityResolve

class micro_bme_handler( xml.sax.ContentHandler ):
    def __init__(self):
        self.CurrentData = ""
        self.ID= ""
        self.ref_system=''
        self.ref_system_ID=''
        self._current_product_data=None 
        self.save_box= [] # list of dict

    def startElement(self, tag, attributes):    # Call when an element starts
         self.CurrentData = tag
         if tag == "ARTICLE": 
             data_product= {'suplier_AID':None, 'System_reference': None, 'FEATURE_GROUP_ID':None}
            self._current_product_data=data_product
            pass
            if tag == "REFERENCE_FEATURE_SYSTEM_NAME": pass
            if tag == "REFERENCE_FEATURE_GROUP_ID": pass       

    def endElement(self, tag):   # Call when an elements ends
        if self.CurrentData == "SUPPLIER_AID":
            self._current_product_data['suplier_AID']= self.ID
        elif self.CurrentData == "REFERENCE_FEATURE_SYSTEM_NAME": 
            self._current_product_data['System_reference']= self.ref_system
        elif self.CurrentData == "REFERENCE_FEATURE_GROUP_ID":
            self._current_product_data['FEATURE_GROUP_ID']= self.ref_system_ID
             self.save_box.append(self._current_product_data)
        self.CurrentData = ""

      def characters(self, content): # Call when a character is read
           if self.CurrentData == "SUPPLIER_AID": self.ID = content
           elif self.CurrentData == "REFERENCE_FEATURE_SYSTEM_NAME": 
                self.ref_system = content
           elif self.CurrentData == "REFERENCE_FEATURE_GROUP_ID":    
                self.ref_system_ID = content

       def skippedEntity(self, name):   
            print ('following entity was skipped from parsing: ', name)

class DTDResolver(EntityResolver):
    def resolveEntity(self, publicId, systemId):
        systemId='......\\BMEcat\\version\\1.2\\bmecat_new_catalog_1_2.dtd'        
        return systemId

您是否知道如何避免DOCTYP验证，或者您看到验证中的内容有误？

提前谢谢
