Extract XML inside another xml having multiple records - xslt

Question

I am pulling clob data from a JDBC server and the below is the sample format of the xml
1
<?xml version="1.0" encoding="utf-8"?>
<Sales_Posting>
<row>
<ORGANIZATION_ID>1</ORGANIZATION_ID>
<RTL_LOC_ID>269</RTL_LOC_ID>
<POSLOG_DATA><?xml version="1.0" encoding="UTF-8"?>
<POSLog xmlns="http://www.nrf-arts.org/IXRetail/namespace/"
xmlns:dtv="http://www.datavantagecorp.com/xstore/"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://www.nrf-arts.org/IXRetail/namespace/ POSLog.xsd" >
<Transaction xmlns:dtv="http://www.datavantagecorp.com/xstore/" CancelFlag="true" OfflineFlag="false" TrainingModeFlag="false" dtv:AppVersion="17.0.0.0.716 - 0.0.0 - 0.0" dtv:TransactionType="RETAIL_SALE" >
<dtv:OrganizationID><![CDATA[1]]></dtv:OrganizationID>
<RetailStoreID><![CDATA[269]]></RetailStoreID>
<WorkstationID><![CDATA[2]]></WorkstationID>
</Transaction>
</POSLog></POSLOG_DATA>
<CREATE_DATE>2019-07-17 20:57:56.536</CREATE_DATE>
</row>
<row>
<ORGANIZATION_ID>1</ORGANIZATION_ID>
<RTL_LOC_ID>269</RTL_LOC_ID>
<POSLOG_DATA><?xml version="1.0" encoding="UTF-8"?>
<POSLog xmlns="http://www.nrf-arts.org/IXRetail/namespace/"
xmlns:dtv="http://www.datavantagecorp.com/xstore/"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://www.nrf-arts.org/IXRetail/namespace/ POSLog.xsd" >
<Transaction xmlns:dtv="http://www.datavantagecorp.com/xstore/" CancelFlag="false" OfflineFlag="false" TrainingModeFlag="false" dtv:AppVersion="17.0.0.0.716 - 0.0.0 - 0.0" dtv:TransactionType="RETAIL_SALE" >
<dtv:OrganizationID><![CDATA[1]]></dtv:OrganizationID>
<RetailStoreID><![CDATA[269]]></RetailStoreID>
<WorkstationID><![CDATA[2]]></WorkstationID>
</Transaction>
</POSLog></POSLOG_DATA>
<CREATE_DATE>2019-07-18 06:20:38.014</CREATE_DATE>
</row>
</Sales_Posting>
I need to pull the xml inside the tag .
For a single record I am able to pull the data using the below code
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" indent="yes"/>
<xsl:template match="/">
<xsl:value-of select="/Sales_Posting/row/POSLOG_DATA"/>
</xsl:template>
</xsl:stylesheet>
But I require it for multiple records.
XSLT 1.0 is preferable. If the result is possible via multiple xslt mappings then that is also fine for me.
Expected Output is :-
2
<?xml version="1.0" encoding="utf-8"?>
<Sales_Posting>
<row>
<POSLog xmlns="http://www.nrf-arts.org/IXRetail/namespace/"
xmlns:dtv="http://www.datavantagecorp.com/xstore/"

<WorkstationID>2</WorkstationID>
</Transaction>
</POSLog>
</row>
<row>
<POSLog xmlns="http://www.nrf-arts.org/IXRetail/namespace/"

<RetailStoreID>269</RetailStoreID>
<WorkstationID>2</WorkstationID>
</Transaction>
</POSLog>
</row>
</Sales_Posting>
I am sharing the image of source structure as well as the expected target structure. Kindly help.

Try:
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:template match="/Sales_Posting">
<xsl:copy>
<xsl:for-each select="row">
<xsl:copy>
<xsl:value-of select="substring-after(POSLOG_DATA, '?>')" disable-output-escaping="yes"/>
</xsl:copy>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
The result must be saved to file before processed further. This is assuming your processor supports disable-output-escaping.
