如何在python中使用<title>
删除名为xml.dom
的所有标签?
答案 0 :(得分:0)
按title
标记选择所有元素,然后使用removeChild
更新
from xml.dom import minidom
xmldoc = minidom.parse("book_xml.xml")
nodes = xmldoc.getElementsByTagName("title")
for node in nodes:
parent = node.parentNode
parent.removeChild(node)
print xmldoc.toxml()
您还可以通过以下方式将新更改写入xml文件:
with open("result.xml","w") as fs:
fs.write(xmldoc.toxml())
fs.close()
