Hi all,

  I'm having a requirement of whenever I click a image that is displayed by performing an action,the values in xml file (here is facebook label)should display in a vf page..here is my code

public class XmlStreamReaderDemo2 {

     public string url{set;get;}  

   public PageReference ImageUrl()     {    

String str = '<socialnetwork><Image><Fieldlabel>FaceBook Url</Fieldlabel></socialnetwork>';      

//  Id id;         System.debug('urlllllllllllllll'+url);     

     PageReference p = new PageReference('?id='+str);      

  //   id=apexpages.currentpage().getparameters().get('image1.field');      

    return p;                 

     }     

public String image1 { get; set; }   

public string ImageUrl{get;set;}     

  public class Network    {     

String name;     

String field;  

   }

   Network[] parsesocialnetwork(XmlStreamReader reader) {     

 Network[] socialnetwork= new Network[0];   

 while(reader.hasNext()) {

         if (reader.getEventType() == XmlTag.START_ELEMENT) {        

     if ('Network' == reader.getLocalName()) {

                Network image1= parseImages(reader);               

  socialnetwork.add(image1);                           

  }        

  }    

     reader.next();    

  }

    return socialnetwork;  

  }

   Network parseImages(XmlStreamReader reader) {     

 Network image1= new Network();      

while(reader.hasNext())   {   

if (reader.getEventType() == XmlTag.START_ELEMENT)  {  

   if (reader.getLocalName() == 'Image')     {    

   reader.next();   

  if (reader.getEventType() == XmlTag.characters)      {    

     image1.name= reader.getText();  

   }   

}    

   if (reader.getLocalName() == 'Fieldlabel')    {   

 reader.next();  

 if (reader.getEventType() == XmlTag.characters)    {  

  image1.field= reader.getText();  

}  

 }

  }  

 reader.next();

 }  

  return image1;         

   }    

public void action()   {  

  XmlStreamReaderDemo2 demo = new XmlStreamReaderDemo2();     

  String str = '<socialnetwork><Image>https://encrypted-tbn2.google.com/images?q=tbn:ANd9GcR6N8xoTIVjKPjpdpvLZjzwrDEAIodzZTpD1ybS-XHZskxE1F0e</Image><Fieldlabel>FaceBook Url</Fieldlabel></socialnetwork>';       

 XmlStreamReader reader = new XmlStreamReader(str);    

  Network socialnetwork = demo.parseImages(reader);  

    System.debug('---------'+socialnetwork);     

 System.debug('---------'+ImageUrl);      // System.debug(socialnetwork.size());    

   ImageUrl=string.valueof(socialnetwork.name);    

 // url = string.valueOf(socialnetwork.field);         

 }             

}

and my vf page is

<apex:page controller="XmlStreamReaderDemo2">

   <Apex:form >    

<apex:pageBlock >     

  <apex:commandButton value="Refer" action="{!Action}" reRender="ImageDisplay"/>

      <apex:pageBlockSection >    

   <apex:outputPanel id="ImageDisplay">        

 <apex:image value="{!ImageUrl}"  >       

<apex:actionSupport event="onclick" action="{!ImageUrl}"/>         

  </apex:image>      

  <!-- <apex:inputtext value="{!url}" size="40"/> -->     

   </apex:outputPanel>      

</apex:pageBlockSection>     

      </apex:pageBlock>  

 </Apex:form>

 </apex:page>

Any help would be sincerely appreciated

Thanks in advance,
