The Execute XPath activity is used for reading and extracting data from
.xml
files.
To exemplify how to use this activity, we have created an example that uses the Execute XPath activity for extracting the name of a person from a
.xml
file.
This is how the automation process can be built:
-
Open Studio and create a new Process.
Note: Make sure to place the.xml
file inside the project folder. For this example we used theXMLfiles.txt
. -
Drag a Sequence to the Workflow Designer.
-
Create the following variables:
Variable Name
Variable Type
Default Value
XMLString
String
Result
Object
-
-
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.
- In the Properties panel, add the name
-
Add an Execute XPath activity after the Read Text File activity.
- In the Properties panel, add the variable
XMLString
in the XMLString field. - Add the value
"string(/catalog/book/author/text()[1])"
in the XPathExpression field. This expression extracts the text found in the author field from thexml
file. - Add the variable
Result
in the Result field.
- In the Properties panel, add the variable
-
Drag a Write Line activity after the Execute XPath activity.
- Add the expression
"Result: " + Result.ToString
in the Text field.
- Add the expression
-
Run the process. The robot extracts the name of the author from the
.xml
file and displays it in the Output panel.
