python - ElementTree 元素索引查找

Question

我正在使用该xml.etree.ElementTree模块从另一个结构化文档中使用 Python 3.1 创建 XML 文档。

我可以使用什么ElementTree函数来返回现有子元素的索引？

Answer 1

getchildren 方法返回 Element 对象的子元素列表。然后，您可以使用列表的内置索引方法。

>>> import xml.etree.ElementTree as ET
>>> root = ET.Element("html")
>>> head = ET.SubElement(root, "head")
>>> body = ET.SubElement(root, "body")
>>> root.getchildren().index(body)
1

Answer 2

import xml.etree.ElementTree as ET
root=ET.Element('C:\Users\Administrator\Desktop\ValidationToolKit_15.9\ValidationToolKit_15.9\NE3S_VTK\webservice\history\ofas.2017-1-3.10-55-21-608.xml')
childnew=ET.SubElement(root,"354")
root.getchildren().index(childnew)
0
list(root).index(childnew)
0

def alarms_validation(self, path, alarm_no, alarm_text):
    with open(path) as f:
        tree = et.parse(f)
        root = tree.getroot()
        try:
            for x in xrange(10000):
                print x
                for y in xrange(6):
                    print y
                    if root[x][y].text == alarm_no:
                        print "found"
                        if root[x][y+1].text != alarm_text:
                            print "Alarm text is not proper"
                        else:
                            print "Alarm Text is proper"
        except IndexError:
            pass
