I would like to manipulate the input transformation script for a form FormField element using API.

here is what I've got so far:

Code:

public void setScript(WrProject project,WrContent content)
        {

            WrScript script = new WrScript();
            //set up new script....???
            content.TranformationScript.IsEnabled = true;
            content.TranformationScript.ScriptType = WrScriptType.InputDataScript;
            content.TranformationScript.ScriptLanguage WebRipperUtils.WrScriptLanguageEnum.Csharp;
            content.TranformationScript.Assign(script);


         
        }


how do i set up a new script?

The property TranformationScript is only there for backward compatibility

You should use:

content.Scripts.GetScript(WrScriptType.ContentTransformation).Assign(script)

I'm having trouble implementing the WrInputTransformationArguments class.

in other words, I want imitate the
TransformInput(WrInputTransformationArguments args) method and assign its content to a WrScript object.

Code:

            WrScript script = new WrScript();
            script.ScriptType = WrScriptType.InputDataScript;
            script.ScriptLanguage = WebRipperUtils.WrScriptLanguageEnum.Csharp;
            content.Scripts.GetScript(WrScriptType.InputDataScript).Assign(script);
            content.Scripts[0].IsEnabled = true;

       WrInputTransformationArguments trans = new WrInputTransformationArguments (???????)


thanks

I'm not quite sure what you are trying to achieve, but you cannot instantiate WrInputTransformationArguments in a stand-alone application, since it is instantiated with parameters that are extracted/calculated during runtime.

so is that means that I cannot create a transformation scripts dynamically using the API?

is there another way to do it?

You can create and add the script to the project, but you cannot run it independently which is when you would be using WrInputTransformationArguments.

It will be great if you can get me started on creating the script. a simple transformation script will do.

I already know how to assign the script to the project element

thanks

Code:

WrScript script = content.Scripts.GetScript(WrScriptType.ContentTransformation);
script.IsEnabled = true;
script.ScriptLanguage = WrScriptLanguageEnum.Csharp;
script.Script = "script code";

ah... okay

and how do I pass project parameters to the script?
can I just do:
Code:
script.Script = "string s = args.Content ; return s;"

??
like the script is running within the VWR application?

I see that I need to write the entire thing in a string.. including the namespace references etc.
something like:
Code:

string s;

s = "using System; using VisualWebRipper.Internal.SimpleHtmlParser; ";
s += " using VisualWebRipper; ";
s += " public class Script{ ";
s += " public static string TransformContent(WrContentTransformationArguments args) ";
s += " { try " ;
s += "  { string test ; test = \" test string \"; return args.Content;} ";
s += "catch(Exception exp){ args.WriteDebug(exp.Message);";
s += "return \"Custom script error\"; } } }";

script.Script = s;


Am I correct?
