Hello,
[1] We have XML file as below

MyExample.XML
<?xml version="1.0" encoding="ISO-8859-1"?>

<IRP_ACCOUNT> ………<IRP_ACCOUNT>

</T0020>

[2] we have table MyTable to insert MyExample.XML Data
FILE_NAME VARCHAR2(120)
IRP_ACCOUNT_NUMBER VARCHAR2(32)
IRP_ACCOUNT_TYPE VARCHAR2(1)
IRP_CARRIER_ID_NUMBER VARCHAR2(12)
IRP_BASE_COUNTRY VARCHAR2(12)
IRP_BASE_STATE VARCHAR2(12)
IRP_STATUS_CODE VARCHAR2(12)
IRP_STATUS_DATE VARCHAR2(10)
IRP_UPDATE_DATE VARCHAR2(10)
XCVIEW_SOURCE_DATA VARCHAR2(100)
XCVIEW_PROC_STATUS VARCHAR2(100)
XCVIEW_PROC_TIME TIMESTAMP(6)



[3] so we have applied MyXSLT .xsl to insert data into database (into table MyTable ),our xslt file is as below.
MyXSLT .xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="FILE_NAME" select="T0020/IRP_ACCOUNT/FILE_NAME"/>

<xsl:template match="/">
<xsl:element name="T0020">
<xsl:apply-templates select="* | T0020/IRP_ACCOUNT"/>
</xsl:element>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="@* | node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="@* | text()">
<xsl:copy/>
</xsl:template>

<xsl:template match="T0020/IRP_ACCOUNT">
<xsl:element name="IRP_ACCOUNT">
<xsl:element name="FILE_NAME">
<xsl:value-of select="$FILE_NAME"/>
</xsl:element>
<xsl:element name="IRP_CARRIER_ID_NUMBER">

<xsl:element name="IRP_BASE_COUNTRY">

<xsl:element name="IRP_BASE_STATE">

</xsl:element>
<xsl:element name="IRP_ACCOUNT_NUMBER">
<xsl:value-of select="IRP_ACCOUNT_NUMBER"/>
</xsl:element>
<xsl:element name="IRP_ACCOUNT_TYPE">
<xsl:value-of select="IRP_ACCOUNT_TYPE"/>

<xsl:element name="IRP_STATUS_CODE">

<xsl:element name="IRP_STATUS_DATE">

</xsl:element>
<xsl:element name="IRP_UPDATE_DATE">
<xsl:value-of select="IRP_UPDATE_DATE"/>
</xsl:element>
</xsl:element>

</xsl:template>

</xsl:stylesheet>

[4] We are insert xml data to database using oracleXMLSave.insert utility for which we have set parameter file name
By oracleXMLSave.setXSLTParam(“FILE_NAME”,”mystestfile”).

Only FILE_NAME Column is value is not coming into the Database.

please help...if you need more details then i can provide...
