    <p>You can't really do this, unfortunately. While Java does support regexpes very well, the WebDriver API does not. Every <code>String</code> parameter in the WebDriver API is taken literally, as a character string, <em>not</em> as a regexp.</p> <p>You have probably confirmed this by running your code. And you have not missed anything, you can't use regexpes in searching for WebElements. If you're wondering why, the reason is that WebDriver has been primarily designed for test automation - you have a front-end test and you don't want to click everything in? Use WebDriver! Are you doing something else? Not sure if you got the right tool for it.</p> <p>Reconsider your approach - <em>why</em> are you trying to match by a regexp? Are you running a website test? Are you not sure what should display there? Well, that's wrong! You should be testing whether you site is behaving like expected.</p> <p>If you're testing after every page load whether the page contains some error message and you are sure you want to do this, consider a different approach. Can you look for a container with <code>id="error-message"</code> or something? Can you look at the URL or a page title whether it contains <code>404 not found</code> or anything similar you need to assert?</p> <p>What you can do?</p> <ul> <li>Try not to search by text if you don't have to.</li> <li>Dive into <a href="http://www.w3.org/TR/xpath/" rel="nofollow noreferrer">XPath 1.0</a> and see what it can do for you. While there are no regexp-enabling functions (<a href="http://www.w3.org/TR/xquery-operators/#func-matches" rel="nofollow noreferrer">those could be found in XPath 2.0</a>, but we can't use that), there's a lot of strength in there. For example, there's no native <code>lower-case()</code> function, you can use <a href="https://stackoverflow.com/questions/1965529/xpath-how-do-you-do-a-lowercase-call-in-xpath"><code>translate()</code></a>. Or simply use multiple <code>contains()</code> calls. And <a href="http://www.w3.org/TR/xpath/#node-sets" rel="nofollow noreferrer">you can use <code>|</code> to union node-sets</a> together. With these two, you could reconstruct your query with a looooooong XPath. But this is one of the last things you should do. It's bad. Very bad.</li> <li><p>If you're still not convinced you shouldn't search for what you're searching, here's probably the easiest way. I'd still consider it bad since you don't know from where is the Error/Warning/Notice coming, some user might have "Warning: Bad user" as his username. But it does your thing.</p> <pre><code>String bodyText = driver.findElement(By.tagName("body")).getText(); boolean containsError = bodyText.matches("[Ee]rror:|[Ww]arning:|[Nn]otice:|[Ee]xception:"); </code></pre></li> </ul>

    1. COHey, thank you a lot! Yes, I want to verify that when opening a page, no errors come up... And I can't figure another way of doing that. And Im willing to accept the risk for the user input probably providing one of these words... But what you said: "Can you look for a container with id="error-message" or something? Can you look at the URL or a page title whether it contains 404 not found or anything similar you need to assert?" is also a good approach, but I will have to do some research on the side handling and showing errors, before I implement that

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
