It depends a bit on what you are trying to parse it into. If your only goal
is to get a PHP array, you can simply not map the title element. The
default structure sabre/xml always give you for that element is this:
[
"name" => "title",
"value" => "dive into mark",
"attributes" => ["type" => "text"]
]
It's only when you use one of the default 'deserializers' that you get
different structures. In the sabre/xml-atom example there's two major ones
used:
1. The valueObject mapper, which is a standard sabre/xml built-in one that
maps PHP classes and properties to XML elements and child elements.
2. An attributeReader/attributeWriter which in the case of sabre/xml-atom
is a custom one.
So if you have an xml tag that you want to extract both an attribute and a
value from, and you hypothetically would want to map that to a PHP class
like this:
class Title {
public $title;
public $value;
}
The correct sabre/xml solution is to write a custom parser like this:
$server->elementMap['{myNamespace}title'] = function($reader) {
$result = new Title();
$result->type = $reader->getAttribute('type');
$result->value = $reader->readText();
$reader->next();
return $result;
};
