XPath contains text: Finding xPath for an element with text

The problem you are facing is because:

    [contains(text()='Some text')]

To get rid of this error try to change it to the following:-

    [text()[contains(.,'Some text')]]

Here the outer [ ] are a conditional that operates on each individual node in that node you can set function text()as a selector that matches all of the text nodes that are children of the context node and it returns a node-set.

Whereas the inner [ ] is a conditional which operates on each node in that node-set.

The function contains() operates on a string. Here it is passed an individual text node (.).
