This extension makes the process of extracting and editing XPath queries on a web page simple. It contains a lot of useful information on how to work with XPath queries.

For this reason, you will not be able to create a query for every single element. For example, you will not be able to find out the number of rows in a table, nor will you be able to find out the name of the color that a web page uses. This is because most of these properties are not unique, which means that there will be more than one web page on a certain website that has the same value.
