The reault output should be:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<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>
	  <span class="regular">line8.</span>
	  <span class="regular">line9.</span>
   </p>
</body>
</html>

For every span element that the class<>'chapter' verify that in every
p the last span element text ends with one character of .?"!
(paragraph ending char).
If it does, copy as is to the output.
Otherwise: Move the span elements from the next p to the current one
and remove the next p completely.

Here is an attempt at solving that with XSLT 2.0:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xpath-default-namespace="http://www.w3.org/1999/xhtml";
  version="2.0">

<xsl:output method="xhtml"/>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

<xsl:template match="p[span[@class ne 'chapter'] and not(matches(span[@class ne 'chapter'][last()], '[.?"!]$'))]"> <xsl:copy> <xsl:apply-templates select="@* | node() | following-sibling::p[1]/node()"/> </xsl:copy> </xsl:template>

<xsl:template match="p[preceding-sibling::p[1][span[@class ne 'chapter'] and not(matches(span[@class ne 'chapter'][last()], '[.?"!]$'))]]"/>

</xsl:stylesheet>

For the posted input using Saxon 9 it produces the described output but I have not tested with other inputs.
