DOMXpath - Get href attribute and text value of an a element
Simplest way, evaluate
is for this task!
The simplest way to obtain a value is by evaluate()
method:
$xp = new DOMXPath($dom);$v = $xp->evaluate("string(/etc[1]/@stringValue)");
Note: important to limit XPath returns to 1 item (the first a
in this case), and cast the value with string()
or round()
, etc.
So, in a set of multiple items, using your foreach
code,
$names = $domXpath->query("//td[@class='name']/"); foreach($names as $contextNode) { $text = $domXpath->evaluate("string(./a[1])",$contextNode); $href = $domXpath->evaluate("string(./a[1]/@href)",$contextNode); }
PS: this example is only for evaluate
's illustration... When the information already exists at the node, use what offers best performance, as methods getAttribute()
, saveXML()
, etc. and properties as $nodeValue
, $textContent
, etc. supplied by DOMNode
.
See @Gordon's answer for this particular problem.
The XPath subquery (at context) is good for complex cases — or symplify your code, avoiding to check hasChildNodes() + loop for $childNodes, etc. with no significative gain in performance.
