'& ' and tag

[Hong Gia Dinh]

Title: '& ' and <o:p> tag

Hi all,

I used '&nbsp' and <o:p> tag in my .xsl file  but it cant not translate these symbols and keep on reporting error message due to transformer cant not translate and null pointer exception, although i

used
<xsl:text disable-output-escaping="yes">&nbsp<xsl:text>
as well as <o:p>

could you all tell me how to solve these?
thanks
