XSLT 1.0 Move of one Segment - xslt-1.0

Question

please tell me, how can i move the Segment "BGM" from "CNT" to "GRP"?
Actually XML:
<?xml version="1.0"?>
<SEEDELFOR>
<AG/>
<CNT>
<TRANSMISSION_DATE>20190307</TRANSMISSION_DATE>
<TRANSMISSION_TIME>113300</TRANSMISSION_TIME> </INTERCHANGE_CONTROL_NUMBER>
</SENDER>
</SENDER_QUALIFIER>
</RECEIVER>
</RECEIVER_QUALIFIER>
</SYNTAX_IDENTIFIER>
</SYNTAX_VERSION>
<BGM>227</BGM>
<GRP>
</IDENTIFIER_BY>
</IDENTIFIER_SU>
</DATE_4>
</REF_ON>
</GRP>
</CNT>
</SEEDELFOR>
Correct output of my XML Should be:
<?xml version="1.0"?>
<SEEDELFOR>
<AG/>
<CNT>
<TRANSMISSION_DATE>20190307</TRANSMISSION_DATE>
<TRANSMISSION_TIME>113300</TRANSMISSION_TIME>
<SENDER></SENDER>
</SENDER_QUALIFIER>
</RECEIVER>
</RECEIVER_QUALIFIER>
</SYNTAX_IDENTIFIER>
</SYNTAX_VERSION>
<GRP>
<BGM>227</BGM>
</GRP>
</CNT>
</SEEDELFOR>
Here´s my XSLT: I tried to copy, but i think it´s better to move the segment?
Edit: Thats my full XSLT: Maybe i have to cominate with other copy segments?
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<!--Copy all of CNT != BGM-->
<xsl:template match="CNT">
<xsl:copy>
<xsl:apply-templates select="*[local-name()!='BGM']" />
</xsl:copy>
</xsl:template>
<!--copy BGM from CNT to GRP-->
<xsl:template match="GRP">
<xsl:element name="GRP">
<xsl:apply-templates />
<xsl:copy-of select="../BGM" />
</xsl:element>
</xsl:template>
<!--copy the data from ADD/CONTACT with Qualifier EM to GRP, so it can be used in the mapping to set EMAIL from Customer-->
<xsl:template match="GRP">
<xsl:copy>
<xsl:for-each select ="./ADD/CONTACT">
<xsl:if test="./QUALIFIER='EM'">
<CONTACT_EMAIL>
<xsl:value-of select="NUMBER"/>
</CONTACT_EMAIL>
</xsl:if>
<xsl:if test="./QUALIFIER='TE'">
<CONTACT_TEL>
<xsl:value-of select="NUMBER"/>
</CONTACT_TEL>
</xsl:if>
<xsl:if test="./QUALIFIER='FX'">
<CONTACT_FAX>
<xsl:value-of select="NUMBER"/>
</CONTACT_FAX>
</xsl:if>
</xsl:for-each>
<!--copy all other nodes-->
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<!--delete IC node-->
<xsl:template match="IC" />
<!--delete FILTER_SET node-->
<xsl:template match="FILTER_SET" />
<!--delete SEE_AG node-->
<xsl:template match="SEE_AG" />
<!--delete ME node-->
<xsl:template match="ME" />
<!--delete ADD node-->
<xsl:template match="ADD" />
<!-- delete segment (ADD) with specified QUALIFER (SU) -->
<xsl:template match="ADD[QUALIFIER='SU']"/>
<!--delete TRANSPORT_DETAILS node-->
<xsl:template match="TRANSPORT_DETAILS" />
<!--delete PACKAGE_DETAILS node-->
<xsl:template match="PACKAGE_DETAILS" />
<!--delete AMOUNT_DETAILS node-->
<xsl:template match="AMOUNT_DETAILS" />
<!--delete IC node-->
<xsl:template match="CONTACT" />
<!-- delete empty nodes -->
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(#*|*|comment()|processing-instruction()) and normalize-space()='']"/>
<!-- delete empty nodes -->
</xsl:stylesheet>
Thanks for your help.
Best regards

The idiomatic approach to "moving" a node from one place to another is:
copy everything as is,
except the node in question, and
copy the node to its new place:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<!-- remove BGM -->
<xsl:template match="BGM"/>
<xsl:template match="GRP">
<xsl:copy>
<xsl:apply-templates/>
<!-- add BGM -->
<xsl:copy-of select="../BGM" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
If you need to modify other nodes, add templates matching them as necessary.

Seems your XML is not well formed. If I have got it right then you can find below xslt to achieve your requirement:
XML can be:
<?xml version="1.0"?>
<SEEDELFOR>
<AG />
<CNT>
<TRANSMISSION_DATE>20190307</TRANSMISSION_DATE>
<TRANSMISSION_TIME>113300</TRANSMISSION_TIME>
<INTERCHANGE_CONTROL_NUMBER />
<SENDER />
<SENDER_QUALIFIER />
<RECEIVER />
<RECEIVER_QUALIFIER />
<SYNTAX_IDENTIFIER />
<SYNTAX_VERSION />
<BGM>227</BGM>
<GRP>
<IDENTIFIER_BY />
<IDENTIFIER_SU />
<DATE_4 />
<REF_ON />
</GRP>
</CNT>
</SEEDELFOR>
An the solution would be:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="*">
<xsl:copy>
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
<xsl:template match="CNT">
<xsl:copy>
<xsl:apply-templates select="*[local-name()!='BGM']" />
</xsl:copy>
</xsl:template>
<xsl:template match="GRP">
<xsl:element name="GRP">
<xsl:apply-templates />
<xsl:copy-of select="../BGM" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>

<!-- remove BGM at CNT-->
<xsl:template match="BGM"/>
<!--copy the data from ADD/CONTACT with Qualifier EM to GRP, so it can be used in the mapping to set EMAIL from Customer-->
<xsl:template match="GRP">
<xsl:copy>
<xsl:for-each select ="./ADD/CONTACT">
<xsl:if test="./QUALIFIER='EM'">
<CONTACT_EMAIL>
<xsl:value-of select="NUMBER"/>
</CONTACT_EMAIL>
</xsl:if>
<xsl:if test="./QUALIFIER='TE'">
<CONTACT_TEL>
<xsl:value-of select="NUMBER"/>
</CONTACT_TEL>
</xsl:if>
<xsl:if test="./QUALIFIER='FX'">
<CONTACT_FAX>
<xsl:value-of select="NUMBER"/>
</CONTACT_FAX>
</xsl:if>
</xsl:for-each>
<!--copy BGM from CNT to GRP -->
<xsl:copy-of select="../BGM" />
<!--copy all other nodes-->
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
