How get mixed content XML/HTM?

问题

I have a mixed content like this:

    <root>
    <element1>
      text
    </element1>
      <element2>
        <text>A <i>b</i></text>
      </element2>
    </root>

I tried this Example to obtain the whole content with including the sub nodes with the tag "<i>", but in these two Examples I use Path to XML:

$reader->XML($xml); or 
$dom->loadXML($xml); $xpath = new DOMXpath($dom);  

and obtaining whole content of the XML. How can I obtain just the result text "A b"?

回答1:

Should be used:

$nodes = $xpath->evaluate(
 '//*|//text()[normalize-space(.) != ""]'
);

Absolute pathway to the source.
