XSLT Transformation incorrectly - xslt

Question

Below is my XSLT and i need to consider all the "Table" tags from XML which has "XYZ" as text in it.
<xsl:template match="/">
<xsl:element name="Root">
<xsl:apply-templates select= "Document"/>
</xsl:element>
</xsl:template>
<xsl:template match="//Table[.//TH[contains(text(), 'XYZ')]]">
<xsl:copy-of select="spext:Converter(., 'true', './TR[5]', '2')"/>
</xsl:template>
Below is my Input XML snippet. This will call method in c# for extracting specific tags from "Table" element passed by XSLT.
<Document>
<Table>
<TR>
<TH>
XYZ
</TH>
<TH>
PQR
</TH>
</TR>
<TR>
<TD>
Test data 1
</TD>
<TD>
Test data 1
</TD>
</TR>
</Table>
<Part>
<p>Hello World! This is some random text!</p>
</Part>
<Part>
<Table>
<TR>
<TH>
XYZ
</TH>
<TH>
PQR
</TH>
</TR>
<TR>
<TD>
Test data 3
</TD>
<TD>
Test data 4
</TD>
</TR>
</Table>
<p>Random Test after!</p>
</Part>
</Document>
My actual transformation output is below
<Root>
<Table>
<XYZ>Test data 1</XYZ>
<PQR>Test data 2</PQR>
</Table>Hello World! This is some random text!
<Table>
<XYZ>Test data 3</XYZ>
<PQR>Test data 4</PQR>
</Table>Random Test after!
</Root>
But desired output should be below
<Root>
<XYZ>
Test data 1
</XYZ>
<PQR>
Test data 2
</PQR>
<XYZ>
Test data 3
</XYZ>
<PQR>
Test data 4
</PQR>
</Root>
XSLT should only consider "Table" elements nothing else but here other tags text is also getting transformed and thus XML is not formed correctly.enter code here
Any help would be appreciated!

A pure XSLT approach to transform the presented input sample to the desired output sample would be
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="Document">
<Root>
<xsl:apply-templates select="//Table[TR/TH[contains(., 'XYZ')]]/TR[TD]"/>
</Root>
</xsl:template>
<xsl:template match="TR">
<xsl:apply-templates select="TD"/>
</xsl:template>
<xsl:template match="TD">
<xsl:param name="pos" select="position()"/>
<xsl:element name="{normalize-space(../../TR[1]/TH[$pos])}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
