Re: [WebMacro-user] Expression Handling Again

[Dan M. <psi...@ya...>]

I guess what I was wondering about was using the api
directly stepping in before the #set places the result
into the context. I was looking into the src for
PropertyMethod and trying to figure out how to get the
result. 

I am using webmacro throughout a webproject, and would
like to use similiar webmacro expression in xml files
which are read and processed. Thanks
