Hi there.

I'm trying to load an XHTML file as a DOMDocument, and get its text using xpath to find the node. Something's going wrong somewhere, but I can't figure out what. <a name="cutid1"></a> I've used xpath a number of times before, from xslt (Xalan and MSXML2) and C++ (libxml2, Xerces and MSXML2), so I thought I had a good idea of what I was doing. The test case I've got this down to (from reading the PHP docs for <a href="/go.php?http://uk.php.net/manual/en/print/function.dom-domxpath-evaluate.php">DOMXPath->evaluate()</a> and <a href="/go.php?http://uk.php.net/manual/en/print/function.dom-domxpath-query.php">DOMXPath->query()</a> is pretty short. The first file is pretty simple - it's just the data file for the second one to load. page1.php <pre> <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <shtml xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Title

Body

page2.php





Home page.


query($path, $context);

        $obj = new ReflectionObject($list);
        print("Search from \"" . $context->nodeName
            . "\" for \"" . $path
            . "\" (" . $obj->getName() . ")\n");

        print("\n");
        for ($i = 0; $i < $list->length; ++$i)
        {
            print("" . $list->item($i)->nodeName . "\n");
        }
        print("\n");
    }

    $dom = new DOMDocument();
    $dom->load("page1.php");
    print("Document Element node name: "
        . $dom->documentElement->nodeName . "\n");

    pathsearch($dom, $dom, "/html/head/title");

    pathsearch($dom, $dom, "/");
    pathsearch($dom, $dom->documentElement, "/");

    pathsearch($dom, $dom, "/*");
    pathsearch($dom, $dom, "/html");
    pathsearch($dom, $dom, "//html");

    pathsearch($dom, $dom->documentElement, ".");
    pathsearch($dom, $dom->documentElement, "./*");
    pathsearch($dom, $dom->documentElement, "./head");
    pathsearch($dom, $dom->documentElement, ".//head");

    pathsearch($dom, $dom->documentElement, ".//head/*");
    pathsearch($dom, $dom->documentElement, ".//head/title");
    pathsearch($dom, $dom->documentElement, ".//head//title");
?>
