Find Replace Element Using Python

I'm trying to search a tag and replace an element in some XML code. Here is my attempt: from xml.dom import minidom dom = minidom.parse('../../../lib/config/folder/config.xml') f

Solution 1:

You'll have to use the Node API to remove and add nodes:

for tag_type in dom.getElementsByTagName('tag_type'):
    while tag_type.hasChildNodes():
        tag_type.removeChild(tag_type.firstChild)
    tag_type.appendChild(dom.createTextNode("Replacement Word"))

Demo:

>>> from xml.dom import minidom
>>> xml = '''\
... <root>
...    <tag_type>
...       Foo
...       Bar
...    </tag_type>
... </root>
... '''
>>> dom = minidom.parseString(xml)
>>> for tag_type in dom.getElementsByTagName('tag_type'):
...     while tag_type.hasChildNodes():
...         tag_type.removeChild(tag_type.firstChild)
...     tag_type.appendChild(dom.createTextNode("Replacement Word"))
... 
<DOM Text node "'Replacemen'...">
>>> print dom.toxml()
<?xml version="1.0" ?><root>
   <tag_type>Replacement Word</tag_type>
</root>
