HTML Xtra Property Metalist

3. Properties

3.10 the Metalist of member

Syntax:
set mylist = the Metalist of member whichcastmember

Purpose:
This property is used to get a list of meta information of the #html cast member.
We have designed that functionality basically for storing and retrieving information about the document itself.

While authoring the html source files, you can include additional informations in the <HEAD> ... </HEAD> part of the html, which is not visible in any browser or the #html cast member. A single meta tag has the following syntax:
<META name="tag1item1" content="tag1item2">
You can use as many consecutive meta tags as you like.

The returned list is a list of lists. mylist (above example) is a list of all parsed meta tags. Each item of this list is a list with two elements, the first one if the value of the name parameter, the second one is the value of the content parameter. These values are strings. As example put the meta of member "html" would give a result like:
[ ["tag1item1","tag1item2"], ["tag2item1","tag2item2"] ]

This property can be tested, but not set.

Notes:

The returned list is a list of lists, in the example above, count(mylist) evaluates the number of meta tags parsed.
The Xtra also parses meta definitions made in the body part of the html source.
The property name was changed since version 1.x to reflect the returned datatype. If you have used version 1.x in your project you can safely change the meta of member to the metalist of member.
Of course you can safely use the meta tags to store any document related information including Lingo commands or anything else, what can be stored in strings.
