To get Value of Xpath at runtime

, ,
1

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();
if(path.length>1)
{

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

	{	
		if(i<path.length-1)
			{

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

					}
			}
		else
			{	
				value = IDataUtil.getString( inputCursor, path[i] );
				inputCursor.destroy();
			}	
	}
}
else
value = IDataUtil.getString( inputCursor, path[path.length] );
inputCursor.destroy();

}
pipelineCursor.destroy();

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

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

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