I’ve been trying to use SimpleXML, but it doesn’t seem to like XML that looks like this:
<xhtml:div>sample <xhtml:em>italic</xhtml:em> text</xhtml:div>
So what library will handle tags that look like that (have a colon in them)?
Say you have some xml like this.
<xhtml:div> <xhtml:em>italic</xhtml:em> <date>2010-02-01 06:00</date> </xhtml:div>
You can access ’em’ like this:
however, if you want the date field, this:
$xml->children('xhtml', true)->div->date; wont work, because you are stuck in the xhtml namespace.
you must execute ‘children’ again to get back to the default namespace:
If you want to fix it quickly do this (I do when I feel lazy):
// Will replace : in tags and attributes names with _ allowing easy access $xml = preg_replace('~(</?|\s)([a-z0-9_]+):~is', '$1$2_', $xml);
This will convert
Kind of hacky and can fail if CDATA NameSpaced XML container blocks are involved or UNICODE tag names but I’d say you are usually safe using it (hasn’t failed me yet).
Colon denotes an XML namespace. The DOM has good support for namespaces.
I don’t think it’s a good idea to get rid of the colon or to replace it with something else as some people suggested. You can easily access elements that have a namespace prefix. You can either pass the URL that identifies the namespace as an argument to the children() method or pass the namespace prefix and “true” to the children() method. The second approach requires PHP 5.2 and up.
