[cellml-dev] Very slow getPositionInXML function in VACSS

Hi Alan & Andrew,

I would have thought this is a very common and presumably solved problem
for XML editors? Perhaps look at what things such as the eclipse XML
editor plugins (e.g. http://www.eclipse.org/webtools/sse/) do?

Best wishes,
Jonathan
