To get Value of Xpath at runtime

Hi ,

I have Input Document “order” and say value of "/order/orderItems/x/y" = 3

In flow service, at run time i am reading the xpath(/order/orderItems/x/y) from config file .

lets say i m assigning the output of config file value to A.

So now A = /order/orderItems/x/y
So at runtime , how do i extract the value of y(which is 3)
If i give {%A%}, i will get the whole Xpath ie /order/orderItems/x/y
But it should be “3”.

Please help me in resolving this.

Use the following code to build a java service.

Note: this will only support Documents if you have document list or string list in the input document it will on support that structure.

  1. Create a variable type String with name “xPath” in input.
  2. create a document type with name"input" in put.
  3. Create a String type with name “value” in output.

map your required document to the input doument and provide the path for the variable to retrieve as input xPath.Ex: test/abc/xyz/variable1

for the above input the service will get the value of variable1 from test/abc/xyz

// pipeline
IDataCursor pipelineCursor = pipeline.getCursor();
String xPath = IDataUtil.getString( pipelineCursor, “xPath” );
String [] path=xPath.split("/");
String value="";

// input
IData input = IDataUtil.getIData( pipelineCursor, “input” );
if ( input != null)
IDataCursor inputCursor = input.getCursor();

for(int i=1;i<path.length;i++)


				input = IDataUtil.getIData( inputCursor, path[i] );
				if ( input != null)
						inputCursor = input.getCursor();

				value = IDataUtil.getString( inputCursor, path[i] );
value = IDataUtil.getString( inputCursor, path[path.length] );


// pipeline
IDataCursor pipelineCursor_1 = pipeline.getCursor();
IDataUtil.put( pipelineCursor_1, “value”, value );

try built in pub.xml.queryXMLNode, you can use either XQL query or WQL query.

Can you pls explain me with one example on how to use pub.xml.queryXMLNode in my case?

Thanks in advance!!

sample code here… hope this helps.
I would suggest you to read the builtin services guide, you might get a better idea!
