• ExistingXMLNode - The XML Node whose attributes are to be retrieved. This field supports only XNode variables. For more information on XNode objects, go here.

• Attributes - An IEnumerable<XAttribute> variable containing the retrieved XML node attributes. For more information on XAttribute objects, go here.

• Private - If selected, the values of variables and arguments are no longer logged at Verbose level.

• DisplayName - The display name of the activity.

1. Open Studio and create a new Process.

   Note: Make sure to place the .xml file inside the project folder. For this example we used the XMLfiles.txt.

2. Drag a Sequence to the Workflow Designer.

   • Create the following variables:

     Variable Name	Variable Type	Default Value
     XMLString	String
     XMLNodes	**IEnumerable<XNode>
     XMLDocument	XDocument

3. Drag a Read Text File activity inside the sequence container.

   • In the Properties panel, add the name Read XML file in the DisplayName field.
   • Add the value "XMLfiles.txt" in the FileName field.
   • Add the variable XMLString in the Content field.

4. Drag a Deserialize XML activity under the Read Text File activity.

   • In the Properties panel, add the variable XMLString in the XMLString field and the variable XMLDocument in the XMLDocument field.

5. Place a Get XML Nodes activity after the Deserialize XML activity.

   • In the Properties panel, add the variable XMLDocument in the ExistingXML field and the variable XMLNodes in the XMLNodes field.

6. Drag a For Each activity after the Get XML Nodes activity.

   • Add the value node in the Item field and the variable XMLNodes in the Values field.
   • Select the System.Xml.Linq.XNode option from the TypeArgument drop-down list.

7. Select the Body of the For Each activity and create a new variable:

   Variable Name	Variable Type	Default Value
   XMLAttributes	**IEnumerable<XAttribute>

8. Add a Write Line activity inside the Body container.

   • Add the expression node.XPathSelectElement("author").ToString in the Text field. This expression selects the name of the author from the .xml page and writes it in the Output panel.

9. Place a Get XML Node Attributes activity after the Write Line activity.

   • In the Properties panel, add the value node in the ExistingXMLNode field and the XMLAttributes variable in the XMLAttributes field.

10. Drag a For Each activity after the Get XML Node Attributes activity.

    • To open the activity, perform a double click.
    • Add the value attribute in the Item field and the variable XMLAttributes in the Values field.
    • In the Properties panel, select the System.Xml.Linq.XAttribute option from the TypeArgument drop-down list.
11. Select the Body of the For Each activity.

12. Drag a Write Line activity inside the Body container.

    • Add the expression attribute.Value in the Text field.
13. Run the process. The robot extracts an attribute and a value from the nodes, in this case, the name of the author and the book id, and displays them in the Output panel.
