# XML Path Syntax

XPath is used to locate the data in the XML object. XPath is currently used in the following two functionalities of vREST:

  1. Variable Extractor tab In the variable extractor tab of a test case, you need to specify the x-path in the "JSON Path / XML PATH / Utility Method" column.
  2. XML Body Assertions In the Assertions tab, you need to specify XPath for XML Body assertions in the "Property" column.

Below are some examples of most common scenarios for XML path expressions.

<?xml version="1.0"?>
<catalog>
   <book id="book1">
      <author>Author Name 1</author>
      <title>Book Title 1</title>
      <genre>Book Genre</genre>
      <price>50</price>
      <publish_date>2010-11-01</publish_date>
      <description>Book Description...</description>
   </book>
   <book id="book2">
      <author>Author Name 2</author>
      <title>Book Title 2</title>
      <genre>Book Genre</genre>
      <price>15</price>
      <publish_date>2010-12-13</publish_date>
      <description>Book Description ...</description>
   </book>
</catalog>
  1. Accessing Node Attribute (Id of first book)
    • XPath Expression: /catalog/book[1]/@id
    • Value: book1
  2. Accessing Node Text Content (Author of first book)
    • XPath Expression: /catalog/book[1]/author/text()
    • Value: Author Name 1

Now, if you are having XML namespaces defined in the XML file as below:

<?xml version="1.0" encoding="utf-8"?>
<sample>
  <hello:table xmlns:table="http://example.com/hello">
    <tr>
      <td>Hello world!!!!</td>
    </tr>
  </hello:table>
</sample>

In the above XML, to access the td element, you may provide the below XPath expressions:

1. /sample/*[local-name()='table' and namespace-uri()='http://example.com/hello']/tr/td/text()
2. /sample/*[local-name()='table']/tr/td/text()
