Modify (Change specific elements) XML file with minidom in python
===

I have n xml file in which I want to change three elements. 
It's the first, eighth and tenth `<string>` element. so the easiest approach, I guess, would be like this (But I am open to any other suggestions, Thanks!!):

    DOM = xml.dom.minidom
    doc = DOM.parse(open(FILENAME))
    
    a = doc.getElementsByTagName('string')
    for i in range(len(a)):
    	if i == 0:
    		a[i] = new Element with new Text
    	if i == 7:
    		a[i] = new Element with new Text
    	if i == 9:
    		a[i] = new Element with new Text

Thats my file basically:

    <plist version="1.0">
    <dict>
    	<key></key>
    	<string>CHANGE THIS</string>
    	<string>aaa</string>
    	<key>aaa</key>
    		<dict>
    			<key>aaa</key>
    			<dict>
    				<key>aaa</key>
    				<string>aaa</string>
    				<key>aaa</key>
    				<false/>
    			</dict>
    			<key>aaa</key>
    			<dict>
    				<key>aaa</key>
    				<string>aaaa.png</string>
    				<key>aaa</key>
    				<string>aaa</string>
    				<key>aaa</key>
    				<string>aaa</string>
    			</dict>
    		</dict>
    		<key></key>
    		<true/>
    		<key></key>
    		<string></string>
    	<key></key>
    	<string>CHANGE THIS</string>
    	<key></key>
    	<string></string>
    	<key></key>
    	<string>AND CHANGE THIS</string>
    	<key></key>
    	<string></string>
    	<key></key>
    	<string></string>
    	<key></key>
    	<key></key>
    	<true/>
    	<key></key>
    	<string></string>
    	<key></key>
    	<key></key>
    </dict>
    </plist>
