I want to expect target xml as below after run xslt.

Answer 1

If I understand correctly, you want your output document to consist of a single D_6066 element containing the count of the number of POSEX elements in the input document.
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<D_6066>
<xsl:value-of select="count(//POSEX)"/>
</D_6066>
</xsl:template>
</xsl:stylesheet>
