Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.While converting CSS class selectors into XPath expressions white spaces are not correctly handled: the current code appends a starting space and trailing one to the class attribute value and does the same with the class value being processed. This approach works only if there is only a space separating every class value, but in more complex cases the resulting XPath expressions does not select element the should be matched, e.g.:
<style type="text/css">
<!--
.value1 {
background: red;
}
-->
</style>
<!-- a newline is separating the class values! -->
<body class="value1
value2">
...
</body>
In this case the body element is not matched by the following XPath expression:
//*[contains(concat(" ",@class," "),concat(" ","value1"," "))]
