I have the following html markup.

<p>
  <i>This is italic tag</i>. This text belongs to x element. The text from here should <sub>2</sub>   belong to y element.
</p>

And here is the template rule I am using:

`<xsl:template match="p/text()[not(parent::i)]">
    <xsl:variable name="tokens" select="tokenize(.,'.')"/>
    <xsl:element name="x">
        <xsl:value-of select="normalize-space($tokens[2])"/>
    </xsl:element>
    <xsl:element name="y">
        <xsl:value-of select="normalize-space(string-join($tokens[position() > 2 and position() != last()], '.'))"/>
    </xsl:element>
</xsl:template>`

`<xsl:template match="sub">
    <xsl:element name="SUBSCRIPT">
        <xsl:apply-templates/>
    </xsl:element>
</xsl:template>`

`<xsl:template match="p">
    <xsl:element name="PARA">
        <xsl:apply-templates/>
    </xsl:element>
</xsl:template>`

`<xsl:template match="i">
    <xsl:element name="EMPHASIS">
        <xsl:apply-templates/>
    </xsl:element>
</xsl:template>`

When running the transformation some text is missing in the output.

This is what I am getting now:

`<PARA>
    <EMPHASIS>This is italic tag</EMPHASIS>
    <X>This text belongs to x element</X>
    <Y/>
    <SUBSCRIPT>2</SUBSCRIPT>
    <X/>
    <Y/>
</PARA>`

What I am expecting:

`<PARA>
     <EMPHASIS>This is italic tag</EMPHASIS>
     <X>This text belongs to x element</X>
     <Y>The text from here should <SUBSCRIPT>2</SUBSCRIPT> belong to y element</Y>      
</PARA>`

How can I make sure that when dividing the p tag’s text node and its element node (child element node except for i child) there is no content loss and sub element is also transformed correctly?
