XPath Transformer

We've already seen that properties can be identified by using the following syntax ${propertyname}. Now this is simple and straightforward but sometimes the contents the property may contain more than just plain text and in those cases we may want to only reference certain elements within the structured data. For this we currently have the ability to apply transformations on the property's data using various data query languages. Currently we support XPath on the any XML data within a property and here's a simple example of how this works:

So lets say we have the property myxml that contains the following xml snipplet:

<list>
   <item>1</item>
   <item>2</item>
   <item>3</item>
   <item>4</item>
   <item>5</item>
   <item>6</item>
</list>

Now lets say we wanted to reference the myxml property but we only want the forth value of the child item in the XML data. This is how we would achieve that: 

 ${myxml:xpath://list/item[3]}

The Xpath language is a standard and all of the information on this standard can be easily found by searching for XPath examples online.
