Re: [Sblim-devel] Help for implementing indication provider

[Dave H. <hel...@li...>]

Hi George,

That is normal.  You are just seeing the "escaped XML" that permits an 
EmbeddedObject to be carried within the response XML.  You are seeing 
the raw XML, as you would see over the wire, if the destination handler 
was a network URL instead of a local file:// URL.

FYI: SFCB 1.4 also supports CDATA encoding instead of escaped XML 
encoding, as controlled by the .cfg property "embeddedObjEncoding".  If 
you change that from "xmlescape" to "CDATA" you will see the difference 
in the XML.  The CDATA encoding is a bit more readable but it's not very 
good an handling nested embedded objects.  That's why "xmlescape" is the 
default in v1.4.
