Re:  Move elements to preceding parent
Hi Martin,
Thank you for this. It looks very elegant.
Can you please explain the idea of the line:
>  <xsl:template match="p[preceding-sibling::p[1][span[@class ne 'chapter']
> and not(matches(span[@class ne 'chapter'][last()], '[.?&quot;!]$'))]]"/>

Does it remove the p  that has preceding sibling with no ending
character at the end of the last span?


I tried it with a more complete example like the following:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
   <meta http-equiv="Content-Type" content="application/xhtml+xml;
charset=utf-8"/>
   <title/>
   <link href="test.css" rel="stylesheet" type="text/css"/>
</head>
<body>
   <p dir="rtl">
      <span class="chapter">line1</span>
   </p>
   <p dir="rtl">&nbsp;&nbsp;<br />
   <span class="regular">line3.</span>
   <span class="italic">line4</span>
   <span class="regular">line5."</span>
   </p>
   <p dir="rtl">&nbsp;&nbsp;<br />
   <span class="regular">line6.</span>
   <br />
   <span class="regular">line7</span>
 </p>
 <p dir="rtl">&nbsp;&nbsp;<br />
   <span class="regular">line8.</span>
   <span class="regular">line9.</span>
 </p>
</body>
</html>


The output was:

<?xml version="1.0" encoding="UTF-8"?><html
xmlns="http://www.w3.org/1999/xhtml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xml:lang="en"
version="-//W3C//DTD XHTML 1.1//EN">
   <head profile="">
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
      <title></title>
      <link href="test.css" rel="stylesheet" type="text/css"
xml:space="preserve" />
   </head>
   <body xml:space="preserve">
      <p dir="rtl" xml:space="preserve">
         <span class="chapter" xml:space="preserve">line1</span>

      </p>
      <p dir="rtl" xml:space="preserve">  <br xml:space="preserve" />
         <span class="regular" xml:space="preserve">line3.</span>
         <span class="italic" xml:space="preserve">line4</span>
         <span class="regular" xml:space="preserve">line5."</span>

      </p>
      <p dir="rtl" xml:space="preserve">  <br xml:space="preserve" />
         <span class="regular" xml:space="preserve">line6.</span>
         <br xml:space="preserve" />
         <span class="regular" xml:space="preserve">line7</span>
           <br xml:space="preserve" />
         <span class="regular" xml:space="preserve">line8.</span>
         <span class="regular" xml:space="preserve">line9.</span>

      </p>
   </body>
</html>


How can I remove the following:
1. extra xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" and
version="-//W3C//DTD XHTML 1.1//EN" inside html element.
2. extra profile="" in head element
3. extra xml:space="preserve" in p, span and br elements.

Thanks, Viente
