have a look at the xml.dom.minidom module.
You can access nodes by getElementsByTagName("Engineer")
Access value of the text node by node.nodeValue
To modify the xml, you will have to set the node value to the desired value
node.nodeValue = newValue
Note that to you will have to write the modified dom object back to the file
to save the changes, just setting the value of nodes will not automatically
do that.
