Confirming the right hyperlink

Hi,
We create rdl files which contains <Hyperlink> elements. The
value for hyperlink is an expression build using report parameters,
field parameters etc and also contains calls to custom assemblies
eg : <Hyperlink>=Parameters!Param1.Value + CustomAssemblyCall + Fields!
someField.Value<Hyperlink>
When this report is rendered by HTML Rendering extension(by specifying
HTML4.0 in the format string passed to render() method) this
<Hyperlink> element is converted to href attribute of the <a> tag.
We have a scenario where we want to test whether this href url
generated is correct or no without deploying the rdl file on the
report server.
Is there any way to pass the xml file and find out what would be href
value when the <Hyperlink>
element is parsed by the report server ?
Any report server dll's which can directly be used ?
Thanks in advance,Can anyone guide me on this
