XPath Using 'contains()'

When an attribute of an element is dynamic then one can use 'contains()' to select the element by using the constant part of the attribute of that web element.

Syntax: 

//tag[contains(@attribute, 'value')]

Example:

XPath = //tag[contains(@name, 'btnClk')]

It searches 'btnClk' for all name attributes in the DOM.

XPath = //tag[contains(text(), 'here')]

It searches the text 'here' in the DOM.

XPath = //tag[contains(@href, 'google.com')]

It searches 'google.com' link in the DOM

Let's get a clear view with the below example:

//span[contains(@class, 'gb_')]

Here, //span[contains(@class, 'gb_')] searches all the 'span' elements which contains 'gb_' as attribute class value.

Another example:

//a[contains(text(), 'ac')]

Here, //a[contains(text(), 'ac')] searches all the 'a' elements which contains 'ac' as attribute text value.
