hi!

i am trying to remove all whitespace elements out of a document.

my code is below

def stripWhiteSpaces(doc):
	whiteSpaces = xpath.Evaluate("//text()", doc.documentElement)
	counter=0
	while(counter< len(whiteSpaces)):
		str = whiteSpaces[counter].nodeValue
		string.strip(str)
		if len(str) == 0:
	       whiteSpaces[counter].parentNode.removeChild(whiteSpaces[counter])

		counter += 1
	return doc

however this isn't working. when i print out all the elements in the
document, i still get the whitespace text elements.
what am i doing wrong?

thanks

cheers
