XPath object identification
In the following lines, the user will find tips for being able to identify the web objects via XPath.
XPath is a way of objects identification based on the path where the element is nested in. As an example, the XPath ”/html/body/div[2]/div/div/footer/section[3]/div/ul/li[3]/a” will search in the html body an element “div[2]”; inside this it will look for a “div”; inside this, another “div”, and then a “footer” and so on and so on…
There are, basically, two different ways to use the XPath, using the complete path, or finding a partial path (for this, instead of opening the sentence with ”/”, they are open with ”/ /”). As always, in testing, it is really important to make sure that the Xpath that we write is unique and represents one element with no possibility of error. As a little reminder, notice that the ID attribute is unique.
Nevertheless, since this way can be too long, there are some ways to shorten it. For this, is necessary to know some syntax related to it:
| XPath Expression | Description | Expression example | Example meaning |
|---|---|---|---|
| / | Selects from the root node | (…)/b/a | Element “a” child of “b”, child of ”(…)“ |
| |Selects any nodes from the current node that match the selection no matter where they are |b a(…) | |||
| * | Matches any element node (wildcard) | b / * / a | |
| . | Selects the current node |
