[xsl] WorldML Filteration

Hi, 
I have got a good clue about formatting elements for worldML. In the similar
effort we need to filter these elements. Comparison of "current output" and
"desired output" is sufficient to understand the requirement.

Input
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t>Azienda</w:t></w:r>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t> </w:t></w:r>
<w:r><w:rPr><w:i/><w:b/><w:i-cs/></w:rPr><w:t>Ospedaliera</w:t></w:r>
<w:r><w:rPr><w:i/><w:b/><w:i-cs/></w:rPr><w:t>, </w:t></w:r>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t>Ospedali</w:t></w:r>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t> </w:t></w:r>
<w:proofErr w:type="spellStart"/>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t>Riuniti</w:t></w:r>

XSLT
<!--Text run container-->
 <xsl:template match="w:r">
  <xsl:choose>
   <xsl:when
test="w:rPr/w:vertAlign|w:rPr/w:u|w:rPr/w:b|w:rPr/w:i|w:rPr/w:smallCaps|w:rP
r/w:highlight">
    <xsl:apply-templates select="w:rPr" mode="styling"/>
   </xsl:when>
   <xsl:otherwise>
    <xsl:apply-templates/>
   </xsl:otherwise>

         </xsl:if>                
       </xsl:element>

     </xsl:otherwise>

 </xsl:template>

Current output
<i>Azienda</i><i> </i><i><b>Ospedaliera</b></i><i><b>,
</b></i><i>Ospedali</i><i> </i><i>Riuniti</i>

Desired output
<i>Azienda <b>Ospedaliera, </b>Ospedali Riuniti</i>
