Question

My first post here. I have searched but haven’t found what I’m looking for.

I am not really sure what technique I need to do the following.

I use Mule 3.3 CE and I need to split XML files. I need to keep the “rootElement” and its attributes in each and every splitted XML. All XML-files will be dropped in the same JMS Queue.

I know how to split the three Product-nodes but how can I keep the “rootElement” on each an every XML-file?

XPath? XSLT? DOM and remove and add nodes?
I would prefer just an XPath but does it have the strength to do this?

<?xml version="1.0" encoding="ISO-8859-1"?>
<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"
           preOrderTo="2012-12-31T23:59:59"
           currency="GBP"
           timeStamp="2012-08-15T23:59:59">
  <Product
             itemID="09999-3-"
             name="Plate"
             description="Plate of blue man"
             tax="0.00"
             eanCode="1234567890123"
             eanType="EAN 13"/>
  <priceBracket quantity="1"
            price="10.98"
            grossPrice="13.00"/>
  <Product
             itemID="12345-3-"
             name="Plate"
             description="Plate of black man"
             tax="0.00"
             eanCode="1234569870123"
             eanType="EAN 13"/>
  <priceBracket quantity="1"
            price="15.98"
            grossPrice="18.00"/>
  <Product
             itemID="98765-3-"
             name="Plate"
             description="Plate of yellow man"
             tax="0.00"
             eanCode="7894567890123"
             eanType="EAN 13"/>
  <priceBracket quantity="1"
            price="20.98"
            grossPrice="24.00"/>
</rootElement>

What I need in Mule 3.3 CE is the following split:

1.

<?xml version="1.0" encoding="ISO-8859-1"?>
<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"
           preOrderTo="2012-12-31T23:59:59"
           currency="GBP"
           timeStamp="2012-08-15T23:59:59">
<Product
             itemID="09999-3-"
             name="Plate"
             description="Plate of blue man"
             tax="0.00"
             eanCode="1234567890123"
             eanType="EAN 13"/>
<priceBracket quantity="1"
            price="10.98"
            grossPrice="13.00"/>
</rootElement>

2.

<?xml version="1.0" encoding="ISO-8859-1"?>
<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"
           preOrderTo="2012-12-31T23:59:59"
           currency="GBP"
           timeStamp="2012-08-15T23:59:59">
  <Product
             itemID="12345-3-"
             name="Plate"
             description="Plate of black man"
             tax="0.00"
             eanCode="1234569870123"
             eanType="EAN 13"/>
  <priceBracket quantity="1"
            price="15.98"
            grossPrice="18.00"/>
</rootElement>

3.

<?xml version="1.0" encoding="ISO-8859-1"?>
<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"
           preOrderTo="2012-12-31T23:59:59"
           currency="GBP"
           timeStamp="2012-08-15T23:59:59">
  <Product
             itemID="98765-3-"
             name="Plate"
             description="Plate of yellow man"
             tax="0.00"
             eanCode="7894567890123"
             eanType="EAN 13"/>
  <priceBracket quantity="1"
            price="20.98"
            grossPrice="24.00"/>
</rootElement>

Answer 1

If you can use XSLT 2.0, here’s one way…

XML Input

<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"
    preOrderTo="2012-12-31T23:59:59"
    currency="GBP"
    timeStamp="2012-08-15T23:59:59">
    <Product
        itemID="09999-3-"
        name="Plate"
        description="Plate of blue man"
        tax="0.00"
        eanCode="1234567890123"
        eanType="EAN 13"/>
    <priceBracket quantity="1"
        price="10.98"
        grossPrice="13.00"/>
    <Product
        itemID="12345-3-"
        name="Plate"
        description="Plate of black man"
        tax="0.00"
        eanCode="1234569870123"
        eanType="EAN 13"/>
    <priceBracket quantity="1"
        price="15.98"
        grossPrice="18.00"/>
    <Product
        itemID="98765-3-"
        name="Plate"
        description="Plate of yellow man"
        tax="0.00"
        eanCode="7894567890123"
        eanType="EAN 13"/>
    <priceBracket quantity="1"
        price="20.98"
        grossPrice="24.00"/>
</rootElement>

XSLT 2.0

<xsl:stylesheet version="2.0" 
    xpath-default-namespace="http://Ecommerce.com/schemas/loyalist/3" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="/*">
        <xsl:apply-templates select="*"/>
    </xsl:template>

    <xsl:template match="Product">
        <xsl:result-document href="{@itemID}.xml">
            <xsl:element name="{/*/name()}" 
                namespace="http://Ecommerce.com/schemas/loyalist/3">
                <xsl:copy-of select="/*/@*|.|following-sibling::priceBracket[1]"/>
            </xsl:element>
        </xsl:result-document>
    </xsl:template>

</xsl:stylesheet>

Resulting XML files (name based on itemID of Product, but could be changed easily)…

09999-3-.xml

<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"
             preOrderTo="2012-12-31T23:59:59"
             currency="GBP"
             timeStamp="2012-08-15T23:59:59">
   <Product itemID="09999-3-"
            name="Plate"
            description="Plate of blue man"
            tax="0.00"
            eanCode="1234567890123"
            eanType="EAN 13"/>
   <priceBracket quantity="1" price="10.98" grossPrice="13.00"/>
</rootElement>

12345-3-.xml

<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"

             currency="GBP"
             timeStamp="2012-08-15T23:59:59">
   <Product itemID="12345-3-"
            name="Plate"
            description="Plate of black man"
            tax="0.00"
            eanCode="1234569870123"
            eanType="EAN 13"/>
   <priceBracket quantity="1" price="15.98" grossPrice="18.00"/>
</rootElement>

98765-3-.xml

<rootElement xmlns="http://Ecommerce.com/schemas/loyalist/3"
             preOrderTo="2012-12-31T23:59:59"
             currency="GBP"
             timeStamp="2012-08-15T23:59:59">
   <Product itemID="98765-3-"
            name="Plate"
            description="Plate of yellow man"

</rootElement>
