WDDX: Web Distributed Data Exchange, or WDDX, is a free, open XML-based technology that allows Web applications created with any platform to easily exchange data with one another over the Web.

Are there any WDDX-parsers for TCL?
Example packet #1:
<wddxPacket version='1.0'> <header comment='Example WDDX packet' /> <data> <string>This is WDDX packet example</string> </data> </wddxPacket>
Example packet #2:
<wddxPacket version='1.0'> <header comment='Another example' /> <data> <struct> <var name='pi'> <number>3.1415926</number> </var> <var name='cities'> <array length='3'> <string>Austin</string> <string>Novato</string> <string>Seattle</string> </array> </var> </struct> </data> </wddxPacket>
LV Based on this example,WDDX appears to be a specific application of XML. There are a couple of XML extensions for Tcl - tdom and tclxml at the very least.
I'm uncertain what one would need to use with either of these to be considered a WDDX parser.
schlenk 2005-10-06 Based on the description of WDDX it seems like a serialization protocol for application data. As Tcl does not really have most of the types of for example Java or C one would have to create a mapping from WDDX to Tcl Data structures, probably something like struct::record or one of the OO packages. With tdom and some XPath expression it should be quite straightforward to do once you decide on a mapping.
Based on a short look at the wddx dtd from the openwddx link above, i can say doing WDDX with Tcl will be quite straight forward. I must also say it doesn't look like the best specification, the authors seem to not understand XML whitespace handling correctly.
