Create a <text:list-style> element from a string or array.
|
|
|
|
List styles require a lot of code to create one level at a time.
|
|
These routines take a string and delimiter, or a list of
|
|
strings, and creates a <text:list-style> element for you.
|
|
Each item in the string (or array) represents a list level
|
|
* style for levels 1-10.</p>
|
|
*
|
|
* <p>If an item contains <code>1</code>, <code>I</code>,
|
|
* <code>i</code>, <code>A</code>, or <code>a</code>, then it is presumed
|
|
* to be a numbering style; otherwise it is a bulleted style.</p>
