Issue Description
lxml.etree.XMLSyntaxError: internal error: Huge input lookup, line 61504, column 702
Expected Behavior
read_xml nead add huge_tree=True
in pandas/io/xml.py
for example:
Old parse_data
:
self.xml_doc = XML(self._parse_doc(self.path_or_buffer))
New:
curr_parser = XMLParser(encoding=self.encoding,huge_tree=True)
self.xml_doc = XML(self._parse_doc(self.path_or_buffer), parser=curr_parser)
Old _parse_doc
:
curr_parser = XMLParser(encoding=self.encoding)
New:
curr_parser = XMLParser(encoding=self.encoding,huge_tree=True)
