It works now.

<xsl:variable name="Lst" >
	<xsl:for-each select="$root/html:tbody/html:tr[position()>1]">
	<xsl:sequence
select="string(normalize-space(current()/html:td[1]/uci:par))" />
	</xsl:for-each>
</xsl:variable>


if you use xsl:variable with no select or as attribute, it always
generaates a sequence of lngth 1, consisting of a single document node
(/).

In this case the / node will have a single text node child consisting of
the strings generated in the for-each, sparated by a single space.


I would guess you want

<xsl:variable name="Lst"  select="
$root/html:tbody/html:tr[position()>1]/html:td[1]/uci:par/normalize-space()"
/>

so you get a sequence of strings.

> I have noticed Lst is sequence of Text types

xpath doesn't have a type called Text, as i say $Lst would have been a
document node with your definition.
