Example 6 with SectionBlock

use of org.xwiki.rendering.block.SectionBlock in project xwiki-platform by xwiki.

the class XWikiDocument method getFilteredHeaders.

/**
 * Filter the headers from a document XDOM based on xwiki.section.depth property from xwiki.cfg file.
 *
 * @return the filtered headers
 */

    // 
    // Note that we need to only take into account SectionBlock that are children of other SectionBlocks so that
    // we are in sync with the section editing buttons added in xwiki.js. Being able to section edit any heading is
    // too complex. For example if you have (in XWiki Syntax 2.0):
    // = Heading1 =
    // para1
    // == Heading2 ==
    // para2
    // (((
    // == Heading3 ==
    // para3
    // (((
    // == Heading4 ==
    // para4
    // )))
    // )))
    // == Heading5 ==
    // para5
    // 
    // Then if we were to support editing "Heading4", its content would be:
    // para4
    // )))
    // )))
