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

<xsl:template match="container/text()">
  <sub-container>
    <xsl:value-of select="."/>
  </sub-container>
</xsl:template>

I would like to convert some legacy data of this format :

<container>
mixed content1 (thus several nodes are possible)
<separator/>
mixed content2
<separator/>
mixed content3
</container>

into

<container>
<sub-container>
 mixed content1
</subcontainer>
<sub-container>
 mixed content2
</subcontainer>
<sub-container>
 mixed content2
</subcontainer>
</container>

I really need an answer.

Thanks a lot
