Change in the rootnode

Old Input xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SalesOrder>
    <SalesOrderHeader>
        <OrderNumber>
            <BuyerOrderNumber>3016</BuyerOrderNumber>
        </OrderNumber>
    </SalesOrderHeader>
    <SalesOrderDetail>
        <ListOfItemDetail>
            <ItemDetail>
                <BaseItemDetail>
                    <LineItemNum>
                        <BuyerLineItemNum>00001</BuyerLineItemNum>
                    </LineItemNum>
                </BaseItemDetail>
            </ItemDetail>
            <ItemDetail>
                <BaseItemDetail>
                    <LineItemNum>
                        <BuyerLineItemNum>00002</BuyerLineItemNum>
                    </LineItemNum>
                </BaseItemDetail>
            </ItemDetail>
        </ListOfItemDetail>
    </SalesOrderDetail>
</SalesOrder>

Old Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL开发者_StackOverflow中文版/Transform" >
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:template match="/SalesOrder">
        <ns0:Z_SALES_ORDER xmlns:ns0="urn:sap-com:document:sap:rfc:functions" >
            <SHEADER>
                <xsl:call-template name="sHeader"/>
            </SHEADER>
            <SITEM>
                <xsl:call-template name="sItem"/>
            </SITEM>
    </ns0:Z_SALES_ORDER>
    </xsl:template>
    <xsl:template name="sHeader">
        <SNUMBER>
            <xsl:value-of select="SalesOrderHeader/OrderNumber/BuyerOrderNumber "/>
        </SNUMBER>
    </xsl:template>
    <xsl:template name="sItem">
        <xsl:for-each select="descendant::ItemDetail">
            <item>
                <B_ITEM>
                    <xsl:value-of select="BaseItemDetail/LineItemNum/BuyerLineItemNum"/>
                </B_ITEM>
                </item>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

Required Output:

<?xml version="1.0" encoding="UTF-8"?>
<ns0:Z_SALES_ORDER xmlns:ns0="urn:sap-com:document:sap:rfc:functions">
    <SHEADER>
        <SNUMBER>3016</SNUMBER>
    </SHEADER>
    <SITEM>
        <item>
            <B_ITEM>00001</B_ITEM>
        </item>
        <item>
            <B_ITEM>00002</B_ITEM>
        </item>
    </SITEM>
</ns0:Z_SALES_ORDER>

Query: Now there is some change in the source xml. In the SalesOrder rootnode they pass other info as well. The input file is below.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SalesOrder xmlns="abc:org.xcbl:schemas/xcbl/v4/xcbl4.xsd" xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://www.w3.org/2003/05/soap-encoding">
    <SalesOrderHeader>
        <OrderNumber>
            <BuyerOrderNumber>3016</BuyerOrderNumber>
        </OrderNumber>
    </SalesOrderHeader>
    <SalesOrderDetail>
        <ListOfItemDetail>
            <ItemDetail>
                <BaseItemDetail>
                    <LineItemNum>
                        <BuyerLineItemNum>00001</BuyerLineItemNum>
                    </LineItemNum>
                </BaseItemDetail>
            </ItemDetail>
            <ItemDetail>
                <BaseItemDetail>
                    <LineItemNum>
                        <BuyerLineItemNum>00002</BuyerLineItemNum>
                    </LineItemNum>
                </BaseItemDetail>
            </ItemDetail>
        </ListOfItemDetail>
    </SalesOrderDetail>
</SalesOrder>

Could you please tell me,how to get the same output which I was getting using the old input xml file.

EDIT Query: In the SalesOrder rootnode they pass other info as well. The input file is below. How to get the rootnode info using XSLT?

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SalesOrder xmlns="abc:org.xcbl:schemas/xcbl/v4/xcbl4.xsd" xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://www.w3.org/2003/05/soap-encoding">
    <SalesOrderHeader>
        <OrderNumber>
            <BuyerOrderNumber>3016</BuyerOrderNumber>
        </OrderNumber>
    </SalesOrderHeader>
</SalesOrder>

Now that the new XML has a namespace you need to qualify your xpath with this namespace. Easiest is to use an alias:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
                xmlns:abc="abc:org.xcbl:schemas/xcbl/v4/xcbl4.xsd"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                exclude-result-prefixes="abc xsl"
                >
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:template match="/abc:SalesOrder">
        <ns0:Z_SALES_ORDER xmlns:ns0="urn:sap-com:document:sap:rfc:functions" >
            <SHEADER>
                <xsl:call-template name="sHeader"/>
            </SHEADER>
            <SITEM>
                <xsl:call-template name="sItem"/>
            </SITEM>
        </ns0:Z_SALES_ORDER>
    </xsl:template>
    <xsl:template name="sHeader">
        <SNUMBER>
            <xsl:value-of select="abc:SalesOrderHeader/abc:OrderNumber/abc:BuyerOrderNumber "/>
        </SNUMBER>
    </xsl:template>
    <xsl:template name="sItem">
        <xsl:for-each select="descendant::abc:ItemDetail">
            <item>
                <B_ITEM>
                    <xsl:value-of select="abc:BaseItemDetail/abc:LineItemNum/abc:BuyerLineItemNum"/>
                </B_ITEM>
            </item>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>
