If your XPath expression is inside the repeating row of a table, then the element corresponding to the row of the table is the context node, say, Row.

•If you use an absolute path, for example $XML/Row/@id, then the XPath expression will return a sequence of the @id values of all Row elements. If you are using an operation that expects one atomic value, the operation will generate an error.

•If you use a relative path, for example @id, then, since for every repeating row, you have a context $XML/Row, the XPath expression will correctly return the single atomic value of the one @id attribute of the current Row element.

If an element with mixed content (text and element/s) is located with an XPath locator expression, then the text content of the mixed-content element only is returned. The text content of descendant elements is ignored.

This is best explained with an example of the Update Node(s) action. Consider the Update Node(s) action defined in the screenshot below.

If the XML tree had the following structure and content:

<Element1>

   <source>AAA

      <subsource>BBB</subsource>

  </source>

  <target></target>

</Element1>

Then the target element would be updated with the text content of the mixed-content element source, while ignoring the content of its child element subsource. The node named target will be updated to <target>AAA</target>.

Note: If you wish to include the text content of descendant node/s, use a string function. Using the XML example above, for instance, the expression string($XML1/Element1/source, '') will return "AAABBB".

Note: Charts use the XPath compliant method of serializing: When a mixed-content element is located using an XPath locator expression, then the text content of descendant elements is also serialized.
