    <p>I'm loading an XML document with <a href="http://us.php.net/domdocument" rel="nofollow">DOMDocument</a>'s <a href="http://us.php.net/manual/en/domdocument.loadxml.php" rel="nofollow">loadXML function</a>. There doesn't appear to be any <a href="http://us.php.net/manual/en/libxml.constants.php" rel="nofollow">options</a> to case fold DOMElement's tagName and attribute names.</p> <p>I need to treat the XML document as being case-insensitive so this should be considered invalid (name and NAME should be the same, not unique):</p> <pre><code>&lt;input name="field" NAME="field2" /&gt; </code></pre> <p>Likewise the getAttribute/setAttribute functions should treat "NAME" AND "name" as the same attribute.</p> <p>The <a href="http://us2.php.net/manual/en/book.xml.php" rel="nofollow">xml parser functions</a> appear to have this functionality through the <a href="http://us2.php.net/manual/en/function.xml-parser-set-option.php" rel="nofollow">xml_parser_set_option</a> function through the "XML_OPTION_CASE_FOLDING" constant. But DOMDocument and these functions appear to be mutually exclusive, with the only similarity being they both use libxml2 behind the scenes.</p> <p>So is there any way to force DOMDocument to case-fold? Are there any drop in replacements that use the xml parser functions? I'm looking to avoid using anything that uses regular expressions. The appeal of DOMDocument is the object vs procedural design.</p> <p>Normally the XML document nodes should be lowercase anyway. But I'd like my code to still work if someone capitalizes something and transform it to lowercase after parsing the document.</p>

    1. COHm, XSLT could do it think. I see a try at [this url](http://www.stylusstudio.com/xmldev/200612/post30020.html)

    2. COI did some experimenting with XSLT. It does work, but it striped out my CDATA tags and encoded the text inside. It also stripped out my DOCTYPE. I'm sure there's probably a way to make it work, but it seemed to mess with the original document more than DOMDocument does.

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.
