After reviewing the answers to the questions regarding how to target elements with multiple classes, I came across this solution:
//div[contains(@class, 'class1') and contains(@class, 'class2')]
However, I have concerns that this method may fail if a div element contains a class attribute that includes either class1 or class2. Is there an established approach for selecting elements with more than one class? Are there any risks associated with using this technique?
A valid point you made is that your XPath query may inadvertently target unwanted @class values:
//div[contains(@class, 'class1') and contains(@class, 'class2')]However, this could pose issues if a tag has a class string that includes class1 or class2
For instance, the aforementioned XPath would select div elements with any of these @class attribute values:
class="class10 class20"
class="notclass1 notclass2"
class="class1class2"
To avoid such scenarios, it's wise to add spaces before and after @class and the specified string:
//div[ contains(concat(' ', @class, ' '), ' class1 ')
and contains(concat(' ', @class, ' '), ' class2 ')]
This refined XPath will prevent matching unintended variations as described above.
