解析xml文件时，显示xml.etree.ElementTree.ParseError: out of memory: line 1, column 0

xml文件大小为1.9G左右

def load_xml(self, file):
        '''function: use the file in XML format
            Args:
                file (str): path to the xml file
            Returns:         
        '''   
        with open(file, 'r', encoding='utf-8') as f:
            xml = f.read()

        #load the xml file
        root = ET.fromstring(xml) #root.tag is document
        for child in root:
                docID = child.find('DOCNO').text #get docID
                content = child.find('TITLE').text + child.find('TAG').text +child.find('ARTIST').text +child.find('YEAR').text +child.find('LYRICS').text #get content
                self.docs_df.loc[docID] = content# use a dataframe to store each doc:docID,content(headline+text)

out of memory，超出内存限制，简单来说，你电脑内存不够
