Question

I would like to write a script which will edit multiple XML files, I would like to have a script which will do the following;

• Find tag “Preload” delete entire
  tag, find “Preload=?sometext?” and delete.
• Find tag “jumpable” delete entire
  tag, find “jumpable=?sometext?” and delete.
• Find “tween” and delete entire tag
• Replace “slide” with “title”, remove this line
• Find “offsety” and delete entire
  tag
• Find “offsetx” and delete entire
  tag
• Find “titleoffsetx” and delete
  entire tag
• Find “presenter” and delete entire
  tag
• Find “controls” and delete entire
  tag
• Find “demooffsetx” and “demooffsety”
  and delete entire tag.
• Replace “flv” with “src”, unless it is “.flv”
• Remove type tag, eg. “type=?sometext?”

Before Script:

 <?xml version="1.0" encoding="utf-8"?>
    <presentation>
      <lesson>
        <part src="0301p.flv" breadcrumb="This is example text1">
          <cuepoints>
            <cuepoint time="0:01" preload="priority" tooltip="Demo 3.1(A)" jumpable="yes">
              <tween mode="instant" time="1" />
              <slide flv="demos/0301d1.flv" demooffsetx="-180" demooffsety="60" type="demo"></slide>
              <presenter />
              <controls />
            </cuepoint>
          </cuepoints>
         </part>
       </lesson>
    </presentation>

After Script:

<?xml version="1.0" encoding="utf-8"?>
<presentation>
  <lesson>
    <part src="0301p.flv" breadcrumb="This is example text1">
      <cuepoints>
        <cuepoint time="0:01" tooltip="Demo 3.1(A)">
          <title src="demos/0301d1.flv"></title>
        </cuepoint>
      </cuepoints>
     </part>
   </lesson>
</presentation>

#!/usr/bin/python

import re

filename = 'editme.txt' #name of the file you want to edit

def edit(filename):
    f = open(filename, 'rU') #reads your file
    text = f.read() #puts everything in file into a string under var text
    f.close() #closes file
    text = re.sub(r'\s[Pp]reload="\w+"', '', text) #delete preload tag
    text = re.sub(r'\s[Jj]umpable="\w+"', '', text) #delete jumpable tag
    text = re.sub(r'<tween.+>\s+', '', text) #delete tween tag
    text = re.sub(r'slide', 'title', text) #replaces slide with title tag
    text = re.sub(r'\s\w+offset\w+=".+"', '', text) #delete offset/type tags
    text = re.sub(r'<presenter.+>\s+', '', text) #deletes presenter tag
    text = re.sub(r'\s+<controls.+>', '', text) #deletes controls tag
    text = re.sub(r'<title flv', '<title src', text) #replaces flv with src in title tag
    f = open(filename, 'w') 
    f.write(text) #replaces all text in file with the edited text
    f.close()

edit(filename)

This simple python script should output what you want.
