PHP DOMElement getAttribute Absolute Path URL?
EDIT: To achieve the URL I wanted, you would have to normalize/canonicalize it, as pointed out my Marc. To accomplish this, you can use a class such as the pear class suggested by Marc, or you could try php's realpath.. however, realpath would not work for me because of some htaccess stuff I'm doing.. but you could use some alternative's such as the one I found here; which seemed to work fairly well.
NOTE: The realpath alternative (truepath) written by Christian Sciberras is a modified version of Sven Arduwies' original script.
Here is some pseudo HTML:
<body><img src="../resources/image.jpg"></body>
Here is the PHP:
$doc = new DOMDocument();
$doc->loadHTMLFile("http://www.foobar.com/project/");
$imageList = $doc->getElementsByTagName("img");
$imageCnt = $imageList->length;
for ($idx=0; $idx<$imageCnt; $idx++) {
echo $image开发者_C百科List->item($idx)->getAttribute("src");
}
The result will be:
../resources/image.jpg
But in reality, what I want is:
http://www.foobar.com/resources/image.jpg
The incoming image paths will not always be consistent; they may be absolute or relative paths, not always from the same domain, and obviously not always the same path.
