Description

Retrieve Extended Data from a content set, a single picture, a single clip, or an actor. The extended data stored is parsed for XML and both the raw data and the parsed XML can be accessed using the following variables created:

• $carma_extended.raw - raw data
• $carma_extended.parsed - XML parsed data

$carma_extended.parsed is the root of the XML data. Each root-tag is an item of that array. XML allows you to have multiple tags with the same name for the same parent, so each tag name points to an array. The parent arrays items are each child tag name in the order they are added. To access attributes of each item, use _attrib and to access cdata of each item, use _cdata. Each item can of course also have child-tags.

For example, the following XML tree,

<data>
<title>The Title</title>
<items>
<item name="test">Foo</item>
<item name="another test">Bar</item>
</items>
</data>

creates the following array structure,

$carma_extended.parsed.DATA[0].TITLE[0]._cdata - "The Title"
$carma_extended.parsed.DATA[0].ITEMS[0].ITEM[1]._attrib.name - "another test"
$carma_extended.parsed.DATA[0].ITEMS[0].ITEM[0]._cdata - "Foo"
