Body
<code>getElementsByTagName</code> works on the whole document. The document has 17 <code>tr</code> elements, so it will return them all regardless where those are placed. As you want to look for specific <code>tr</code> elements, or more specifically for images inside a specific table, I suggest you let xpath do most of the work: <pre><code>$xpath = new DOMXPath($xml); $nodes =$xpath->query("//table[@id='machine']/tbody/tr/td/div/a/img"); echo 'Found ', $nodes->length, ":\n"; foreach($nodes as $node) { $img = $node; $a = $node->parentNode; $aHref = $a->getAttribute('href'); $imgSrc = $img->getAttribute('src'); printf("Element:\n + href: %s;\n +- src: %s\n\n", $aHref, $imgSrc); } </code></pre> This will list 3 elements already (not 2). You need to further on decide which ones to drop, but this should make it more easy. <a href="http://codepad.org/ogEIGM4a" rel="nofollow">Demo</a> & Output: <pre><code>Found 3: Element: + href: /photos.php?id=7135&p=1; +- src: /class/class_Image.php?load=cGhvdG9zL0ExMTk0LmpwZ3wyNTB8MjUwfDF8 Element: + href: /photos.php?id=7135&p=2; +- src: /class/class_Image.php?load=cGhvdG9zL0ExMTk0XzEuanBnfDI1MHwyNTB8MXw= Element: + href: /machine-print.php?id=7135; +- src: http://www.sterlingmachinery.com/images/quick_quote.jpg </code></pre> Another tip: First normalize your data into a structure like an array. You can then use your array to generate the output. That done you can separate the parsing from the output which will make it more easy for you to achieve your goals. <ul> <li>Parse the document into an array.</li> <li>Modify values as you need them in that array (e.g. <code>GetMainBaseFromURL</code>).</li> <li>Generate the output based on the array.</li> </ul>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
