Parsing iTunes RSS Feed

Sivakatirswami,

the colon thing is what is called a namespace. this way you can group  
some tags as belonging to one namespace. This is done to avoid  
collisions such when a XML has mixed info in it added by two  
different specs and both use the same tag so <itunes:summary> is a  
summary tag belonging to iTunes namespace and <andre:summary> would  
be a summary tag added by me. They would not mix.

libXML2 supports this thing but this is not exposed in RevXML upper  
layers. You have two options for parsing this: One is to use Ken Ray  
XML Lib that treats them all like strings and can cope with name  
spaces just fine. Or if you want to use RevXML then use a REGEX match  
to find every ":" inside < > signs, convert them to dashes "-", goog,  
your tag now looks like <itunes-summary> and you're able to use it  
with RevXML.

Hope I helped.
Andre
