Tutorial Addendum On XSL-FO and XHTML - XSL-FO - Block and Inline Areas

XSL-FO Archetype - block.fo

    

Let s do some absorbing tests on block and inline statements:

    

 <?xml version="1.0" encoding="utf-8"?>

    
<!-- block.fo

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">

    
 <fo:layout-master-set>

    
  <fo:simple-page-master master-name="page" margin="0.5in">

    
   <fo:region-body/>

    
  </fo:simple-page-master>

 <fo:page-sequence master-reference="page">

   <fo:block background-color="#ffffff">

    
    1. Authentic argument in a block statement.

    
   </fo:block>

    
   <fo:block background-color="#dfdfdf">

    
    <fo:inline>2. Authentic </fo:inline>

    
    <fo:inline font-weight="bold">inline elements</fo:inline>

    
    <fo:inline> in a block statement.</fo:inline>

   <fo:block background-color="#ffffff">

    
    5. Argument alloyed with 

    
    <fo:block font-weight="bold">block elements</fo:block>

    
     in a block statement.

    
   </fo:block>

    
   <fo:block background-color="#dfdfdf">

     8. Argument alloyed with 

    
     <fo:block font-weight="bold">block elements</fo:block>

    
      in an inline statement.

    
    </fo:inline>

 </fo:page-sequence>

    
</fo:root>

    

If you use FOP to catechumen simple_page.fo to PDF:

    

 run_fop -fo block.fo -pdf block.pdf

    

Print block.pdf, and you will see:

    

 

    
    1. Authentic argument in a block statement.

    
    2. Authentic inline elements in a block statement.

    
    3. Authentic 

    
    block elements

    
    in a block statement.

    
    4. Argument alloyed with inline elements in a block statement.

    
    5. Argument alloyed with in a block statement.

    
    block elements

    
    5. Argument alloyed with in a block statement.

    
    6. Inline elements alloyed with in a block statement.

    
    block elements

    
    6. Inline elements alloyed with in a block statement.

    
    7. Argument alloyed with inline elements in a block statement.

    
    8. Argument alloyed with in an inline statement.

    
    block elements

    
    8. Argument alloyed with in an inline statement.

    

Obviously, there is a problem with bond argument or inline areas with block areas.

    

All texts and inline areas are calm and concatenated calm afore processing

    

the all sub nodes (text, inline and block areas are sub nodes from the XML point of view).

    

While stacking areas, a block breadth will breach the accepted inline stack, and alpha a new block;

    

a argument bulge will be replaced by the concatenated version.

    

If you don t wish to arrest the inline stacking process, use the "wrapper" statement.

    

For example:

    

    <fo:block background-color="#ffffff">

    
    Argument can be cautiously alloyed with 

    
    <fo:wrapper font-weight="bold">wrapper elements</fo:wrapper>

    
     in a block statement.

    
   </fo:block>
