Why Am I Getting a 'Not a Valid XPath Expression' Error in Selenium Java?

Invalid XPath Expression in Selenium Java

When working with Selenium in Java, locating elements becomes essential. However, encountering errors like "Not a valid XPath expression" can be frustrating. This error occurs when the XPath provided violates certain syntax rules.

One common reason for this error is the improper use of quotes for attribute values within the XPath. If you are using single quotes (') to enclose the XPath, you should not use single quotes within the attribute values as well. Instead, consider using double quotes (").

Another potential issue arises when the XPath ends with a forward slash (/). An XPath should typically terminate with the desired element or node. Removing the trailing forward slash can resolve the issue.

Example

Consider the following invalid XPath:

'//*[@id='app']/article/div[2]/section/div[1]/div[5]/div/section[2]/div[2]/div[1]/'

The issues in this XPath are:

• The attribute value for 'id' is enclosed in single quotes, while the XPath itself is enclosed in single quotes.
• The XPath ends with a forward slash.

The correct XPath would be:

'//*[@id="app"]/article/div[2]/section/div[1]/div[5]/div/section[2]/div[2]/div[1]'

or

"//*[@id='app']/article/div[2]/section/div[1]/div[5]/div/section[2]/div[2]/div[1]"

Using either of the above XPaths should resolve the "Not a valid XPath expression" error.
