How Can I Query Div Elements with Multiple Class Names?

Querying Div Elements by Multiple Class Names

In the scenario where a web element has multiple class names, the query using className with space-separated values is infeasible due to its limited functionality. To address this issue, there are several alternative approaches available.

XPath Locators:

XPath allows for the use of multiple criteria in element identification. For example, the following expression will match elements with both "value" and "test" classes:

//div[contains(@class, 'value') and contains(@class, 'test')]

CSS Selectors:

CSS Selectors offer a concise and efficient alternative. The "*" character can be utilized to match any value within a class name.

div[class*='value test']

In cases where the order of the specified classes doesn't matter, the following selector can be employed:

div.value.test

Custom Implementations:

For more complex queries, custom implementations using JavaScript or browser APIs may be necessary.

Examples:

Consider the following HTML structure:

<div class="value test"></div>
<div class="value test     "></div>
<div class="first value test last"></div>
<div class="test value"></div>

The following table illustrates how the different approaches would match these elements:

Approach	Matching Elements
By.xpath("//div[@class='value test']")	1
By.xpath("//div[contains(@class, 'value test')]")	1, 2, 3
By.cssSelector("div[class='value test']")	1
By.cssSelector("div[class*='value test']")	1, 2, 3
By.cssSelector("div.value.test")	1, 2, 3, 4

By selecting the most appropriate approach for the specific element identification needs, developers can effectively locate web elements with multiple class names.
