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:

fortag_typein 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>
