How do I extract link text from anchor tag as well as the URL from

--000feae85bc7b31a2304713d4ef0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

I have the following code to extract the URLs from the anchor tags of an
HTML page:

$html = new DOMDocument();
$htmlpage->loadHtmlFile($location);
$xpath = new DOMXPath($htmlpage);
$links = $xpath->query( '//a' );
foreach ($links as $link)
{ $int_url_list[$i++] = $link->getAttribute( 'href' ) . "\n"; }

If I have a link , how do I extract the
corresponding YYYY which is displayed to the user as the text of the link
(if it's an image tag, I would like a DOMElement for that).
Thanks

Re: How do I extract link text from anchor tag as well as the URL from the "href" attribut

try

$link->nodeValue()

or

$link->getContent()

im not shure which one works on an image link which is indeed a child of so u could also check if the node has a child, if so its an image with, in
good practice. an alt attribute to use

haven't tried but should work. let me know pls

It did not work. Both gave me a "Call to undefined method" fatal error.

Re: How do I extract link text from anchor tag as well as the URL from the "href" attribut

did u try it something like this

foreach ($links as $link) {
$int_url_list[$i]["href"] = $link->getAttribute( 'href' );
$int_url_list[$i++]["linkText"] = $link->getContent( ); // nodeValue();
}
that should work

Re: Re: How do I extract link text from anchor tag as well as the URL from the "href" attr

I found this iteration over the item collection
for ($i = 0; $i < $items->length; $i++) {
echo $items->item($i)->nodeValue . "\n";
}

check here as well
http://us.php.net/manual/en/domnodelist.item.php

doesn't seem a simple foreach dos it

I pasted the code exactly as you have it, and I got the following:

*Fatal error*: Call to undefined method DOMElement::getContent()

I got the same thing with nodeValue().

WHile waiting for suggestions for extracting the link text from the DOM, I
tried a brute force approach using the URLs I had found with getAttribute(),
but found myself baffled by my results. I boiled down my issue with this
approach to the following snippet.

$htmldata =<< http://www.protools.com/users/user_story.cfm?story_id=1162&a mp;lang=1"> "Creating

Surround Mixes with Tim Weidner" src="new.gif" width="28">
- Magnification engineer talks about mixing the album at
the
ProTools site, by Jim Batchco
http://www.beyondmusic.com/MediaPlayer/Yes/DontGo.html">"Don't
Go" Video
- Presented by Beyond
Music
(

Required)
EOB;
$url = 'http://www.beyondmusic.com/MediaPlayer/Yes/DontGo.html';
$posn = strpos($url, $htmldata);
echo "URL |$url| position is |$posn|";

Running this gives me:

URL |http://www.beyondmusic.com/MediaPlayer/Yes/DontGo.html| position is ||

I've tried lots of functions, and even regular expressions, but I cannot get
the code to find the URL in the HTML. While I still hope for a DOM solution
to getting this link text, WHY can't the code find the URL in the HTML
snippet?

this worked here:

$html = new DOMDocument();
$html->loadHtmlFile("testHtml.html");
$links = $html->getElementsByTagName('a');
echo "

foreach ($links as $item) {

  echo $item->getAttribute( 'href' ). "\n";

You may want to try this HTML parser class that comes with filter class
and an example script named test_get_html_links.php that does exactly
what you ask.

Hello,

You might also want to try using the Raxan framework:

require_once 'raxan/pdi/gateway.php';

$page =3D new RichWebPage('page.html');
echo $page['a']->text(); // this will get the text betwen the a tag
=A0
To get the image element use:

$elm =3D $page['a img']->node(0);

You can download Raxan here:
