讀取XML文件

只要xml原文件標籤完整、正確，哪怕是下圖形式的內容，都可以獲取標籤的內容

代碼總結：

from lxml import etree
import xml.etree.ElementTree as ET


class WoFullParser(object):
    if __name__ == '__main__':
        # 方法一
        xml_file = open('WO2018172090A1.XML', mode='rb')
        content = xml_file.read()
        selector = etree.HTML(content)
        p_list = selector.xpath('//p[@id="p0006"]/text()')
        print(p_list)

        # 方法二，包含3中遍歷方法
        tree = ET.ElementTree(file = 'WO2018172090A1.XML')
        root = tree.getroot()
        print(root)
        
        # 2.1
        for child_of_root in root[0]:
            print(child_of_root.tag, child_of_root.attrib, child_of_root.text)

        # 2.2
        for elem in tree.iter(tag = 'p'):
            print(elem.tag, elem.attrib, elem.text)

        # 2.3
        for ele in tree.iterfind('description/p'):
            print(ele.attrib, ele.text)
