Subject: Re: REXML: parsing a string with unescaped ampersand entitie

Did anyone actually find out a solution to this issue.

I have an ActiveResource object which returns back some xml content (as 
a result of a web service call) with unescaped "& " and this causes the 
same issue.

Wondering if we can customize the method call to 
REXML::Text.initialize() and set raw=>false.

Tried to change the setting in the REXML library that comes with the 
Ruby distribution, but that did not help.

Is there a way to overcome this issue without patching any of Ruby or 
Rails code. I cannot change the content on the web service server.


Thanks,
Maruthy.
