Getting text content with xpath - php

Question

I have some HTML like this:
<dd class="price">
<sup class="symbol">$</sup><span class="dollars">58</span><sup class="cents">.00</sup>
</dd>
What's the xpath to get $58.00 back as one string?
I'm using PHP:
$xpath = '?????';
$result = $xml->xpath($xpath);
echo $result[0]; // want this to show $58.00, possible?

Answer 1

These are valid in your case, check for more detail the links below;
$html = '<dd class="price">
<sup class="symbol">$</sup><span class="dollars">58</span><sup class="cents">.00</sup>
</dd>';
$dom = new DOMDocument();
$dom->loadXML($html);
$xpt = new DOMXpath($dom);
foreach ($xpt->query('//dd[#class="price"]') as $node) {
// outputs: $58.00
echo trim($node->nodeValue);
}
// or
$xml = new SimpleXMLElement($html);
$res1 = $xml->xpath('//dd[#class="price"]/sup');
$res2 = $xml->xpath('//dd[#class="price"]/span');
// outputs: $58.00
printf('%s%s%s', (string) $res1[0], (string) $res2[0], (string) $res1[1]);
DOMDocument
DOMXPath
SimpleXMLElement

Answer 2

data() will return all contents inside the current context. Try
//dd/data()

Answer 3

You haven't shown us your code so I don't know what platform you're using. If you have something that can evaluate non-node XPath expressions, then you can use this:
string(//dd[#class = 'price'])
if not, you can select the node,
//dd[#class = 'price']
and the API you're using should have a way of getting the inner text value of the selected node.
