Re: [xsl] position= and blocks (was And operator usage in XSL)

["john farrow" <fomailinglist@xxxxxxxxxx>]

Thats for the info Eliot.

I have been looking at this and came up with this to place the two blocks
over one another:

<fo:block id="outer">
   <fo:block-container absolute-position="absolute">
      <fo:block>A</fo:block>
   </fo:block-container>
   <fo:block>B</fo:block>
</fo:block>

I think (please correct me if I am wrong) only one block-container is
necessary, and it will be positioned relative to its containing area (with
id="outer") so the two blocks will be over each other, and only the second
fo:block is in the normal flow.

So the whole file to test this is:


<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";>
 <fo:layout-master-set>
  <fo:simple-page-master master-name="front-page" margin="1.5cm"
page-height="297mm" page-width="210mm">
   <fo:region-body region-name="body" margin="0.75cm 0.5cm 0.75cm 3cm"/>
  </fo:simple-page-master>
 </fo:layout-master-set>
 <fo:page-sequence master-reference="front-page" initial-page-number="1">
  <fo:flow flow-name="body">
   <fo:block>
      <fo:block-container absolute-position="absolute">
         <fo:block>A</fo:block>
      </fo:block-container>
      <fo:block>B</fo:block>
   </fo:block>
  </fo:flow>
 </fo:page-sequence>
</fo:root>

Any thoughts ?

John
