我需要从下面的 xml 中获取值。
我有一个 Django Rest 框架，它提供以下 XML -

我正在编写另一个需要获取 <jobmst_id></jobmst_id> 的应用程序元素值，因为我想在保存文件时使用该值作为文件名。
我已经保存了部分，但我不确定如何获取元素值。
fullsrcurl = self.srcjson + '?format=xml&jobname=' + job
fulltrgurl = self.targetjson + '?format=xml&jobname=' + job
file = urllib2.urlopen(fullsrcurl)
doc = etree.parse(file)
data = etree.tostring(doc, pretty_print=True)
file = 'c:\\temp\\deployments\\DEV\\test.xml'
xmlsave = open(file, 'w')
xmlsave.write(data)
xmlsave.close
最佳答案
您可以使用文档中的 XPath 语法 here :
root = ET.fromstring(data)
jobmst_id_tag = root.find('./list-item/jobmst_id')
jobmst_id_value = jobmst_id_tag.text
print jobmst_id_value
这给出:
3493
