How to deletw Rows with duplicate data element?

Hello,

How do I delete rows with duplicate Child in my xml file? For example if my xml file contains

<Row>
<Item>1</Item>
<Child>1</Child>1
</Row>
<Row>
<Item>2</Item>
<Child>1</Child>1
</Row>
<Row>
<Item>3</Item>
<Child>2</Child>1
</Row>
<Row>
<Item>4</Item>
<Child>1</Child>1
</Row>

I would like to create a new xml file with the following data (removing Rows with duplicate Child)

<Row>
<Item>1</Item>
<Child>1</Child>1
</Row>
<Row>
<Item>3</Item>
<Child>2</Child>1
</Row>

I am uding VB.NET (VS2010)
Thanks,

Victor

You could use a simple XSLT

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="1.0">
<xsl:key name="row" match="Row" use="Child"/>
    <xsl:template match="node()">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates select="node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="Row[generate-id() = generate-id(key('row', Child)[1])]">
        <xsl:copy-of select="."/>
    </xsl:template>
    <xsl:template match="Row[not(generate-id() = generate-id(key('row', Child)[1]))]"/>
</xsl:stylesheet>
