Guide maker to support range of units help

Hello, I am struggling to make this incorportate units say if a user types 20px or 30pt or 60cm etc 

Also it spits out an xml file to the document folder from which it can read past settings a user inputed, this would need to also read say 20px et 

Help on this would be most useful 

Best

UnitValue can be used for unit conversion. For detailed usage, refer to JavaScript Tools Guide.pdf.

var ptValue = new UnitValue(10, 'mm').as('pt') ;
alert(ptValue) ;

 

This may be unnecessary advice, but ExtendScript can parse XML and search with XPath, so it may be easier than using regular expressions.
