[xsl] Need to process mixed content(text() and node()) in string matching

[Mandar Jagtap <mandar.jagtap@xxxxxxxxx>]

Hi,

I have following scenario:

Source xml is:

<p>This is paragraph text.. <b>and bold</b> and normal <i>and
italic</i> with value: ParagraphValue.</p>

The XSLT should match the string (mixed with text() of <p>, content of
element <i>, <b>) as " This is paragraph text..and bold and normal and
italic with value" in <p> element and desired output given below.

<paragraph1>This is paragraph text.. <b>and bold</b> and normal <i>and
italic</i> with value</paragraph1>
<paragraph2>ParagraphValue.</paragraph2>

I tried with following approach:

<xsl:template match="p">
  <xsl:choose>
    <xsl:when test="contains(. , ':')">
      <paragraph1><xsl:value-of select="substring-before(., ':')"/></paragraph1>
      <paragraph2><xsl:value-of select="substring-after(., ':')"/></paragraph2>
    </xsl:when>
   <xsl:otherwise><paragraph1><xsl:avlue-of
select="."/></paragraph1></xsl:otherwise>
  </xsl:choose>
</xsl:template>

But with I could get only string but not elements <b> and <i>
alongwith its content.

Any suggestions on what would be best approach to achieve this?

Thanks in advance...
