KB73059616: Automation Engine - How to define an XPath expression in an XPath SmartName

Context

XPath uses path expressions to select nodes or node-sets in an XML document.

These nodes:

• Have no value defined.
• Can have a different position in the XML file each time.

XPath expressions can extract an attribute value from another attribute in the same string.

Procedure

E.g. In the following XML file, you want to extract the attribute value att3 where the att1 value is bring:

<?xml version="1.0" encoding="UTF-8"?>
<parent>
<child att1="red" att2="green" att3="black" />
<child att1="car" att2="buss" att3="plane" />
<child att1="dog" att2="cat" att3="child" />
<child att1="bring" att2="jump" att3="walk" />
</parent>

To do so:

1. Go to SmartName dialog.
2. In the XPath expression to evaluate field, you enter: //parent/child[@att1='bring']/@att3
