Getting xerces-c-3.0.1 and libcurl to play together

["Dantzler, DeWayne C" <de...@boeing.com>]

The problem is that there is a proxy between Xerces and the outside world and I need Xerces to perform XML validation
against a schema which includes online references to an external schema 
(e.g <xs:import  > namespace="http://www.w3.org/myspace schemaLocation="http://www.w3.org/schema.xsd"/>.

I built Xerces 3.0.1 to use libcurl(--enable-netaccessor-curl). Now, I assume Xerces has an API which wraps libcurl's
API to allow Xerces to set the proxy host and port similar to what Xerces-j does to set system properties: "http.proxyHost" and "http.proxyPort". Can someone point me to the documentation on this API? Otherwise, why compile Xerces to use libcurl?  

Here's how Xerces-j handles this use case:
$ java -Dhttp.proxyHost="www-stl-proxy4.MyProxy.com" -Dhttp.proxyPort="8160" -classpath SimpleParser.jar;xercesImpl.jar JavaXMLParse filename.xml filename.dtd

In a nutshell,how can I do this with Xerces-C++ using libcurl?

ok, can someone explain to me if Xerces is configured to compile with libcurl(--enable-netaccessor-curl)how Xerces uses
this library? Otherwise, under what condition would it be necessary to do this? 

Thanks

See this page for more information about using environment variables for 
libcurl:

http://curl.haxx.se/libcurl/c/libcurl-tutorial.html

For what I can see from the code, there's no Xerces-C specific way to 
set proxy information. If you think this would be a valuable feature, 
please open a feature request in Jira.
