[XXE] Testing Url exist

[Tongue, Steve]

Hi 

Hoping someone here may be able to help me.

I'm trying to see if a file exists in my subversion repository before trying
to create a new file and see that there is a java command but I can't seem
to get it to work. I'm not a java user so would be grateful for any help.

The command I've tried is

<command name="urltest">
  <macro>
      <sequence>

       <choice>
               <sequence>
                    <test xmlns:url="java:java.net.URL
"expression="url:exists('http://www.xmlmind.com/xmleditor/index.html') =
true" />
                    <command name="alert" parameter="Found"/>
               </sequence>
               <sequence>
                 <test xmlns:sys="java:java.lang.System"
expression="sys:exists('http://www.xmlmind.com/xmleditor/index.html') =
false" /> 
                    <command name="alert" parameter="Doesn't exists"/>
               </sequence>


        </choice>
      </sequence>
    </macro>
 </command>

Cheers
Steve
