Renaming an element with name Standard into Produc

问题:

I had to transform following xml input,

<Standards xmlns="http://ws.wso2.org/dataservice">
        <Standard>
            <ProductID>200057</ProductID>

into the following output format.

With the support from the others in the forum I was able to write the following xslt to do this transformation.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:x="http://ws.wso2.org/dataservice"
    xmlns="http://ws.wso2.org/dataservice"
    exclude-result-prefixes="x"
    version="1.0">

    <xsl:output indent="yes" method="xml" />

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

    <xsl:template match="x:Standard">
        <xsl:copy>
            <xsl:copy-of select="x:ProductID"/>
            <xsl:copy-of select="x:Prefix"/>
            <xsl:copy-of select="x:SNumber"/>
            <RelatedProducts>
                <xsl:apply-templates select=".//x:RelatedProduct"/>
            </RelatedProducts>
            <xsl:copy-of select="x:S1"/>
            <xsl:copy-of select="x:S2"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="x:RelatedProduct">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
            <RelationType><xsl:value-of select="name(..)"/></RelationType>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

But now I need to rename all the elements currently named as Standard into Product and the final output should be as follows.

<Standards xmlns="http://ws.wso2.org/dataservice">
    <Product>
        <ProductID>200057</ProductID>

I tried several approaches and changed the above xslt, but still there's no luck. I am a novice to xslt. How can I change the above xslt to get this thing done. Any help would be appreciated.

回答1:

Just replace the <xsl:copy> in

<xsl:template match="x:Standard">
                <xsl:copy>
                    <xsl:copy-of select="x:ProductID" />

with <Product> (and the closing tag, too, of course). It's that easy without modifying something else, giving

<xsl:template match="x:Standard">
                <Product>
                    <xsl:copy-of select="x:ProductID" />

Result is:

<?xml version="1.0"?>
<Standards xmlns="http://ws.wso2.org/dataservice">
    <Product>
        <ProductID>200057</ProductID>
        <Prefix>ISO</Prefix>
        <SNumber>1001</SNumber>
        <RelatedProducts>
            <RelatedProduct>
                <ProductID>1500163</ProductID>
                <RelationType>DraftProducts</RelationType>
            </RelatedProduct>
            <RelatedProduct>
                <ProductID>263973</ProductID>
                <Designation xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
                <RelationType>ReferenceProducts</RelationType>
            </RelatedProduct>
            ...

If you want to also copy the RelationId just remove the exeception from the last template, so that it looks like this:

<xsl:template match="x:RelatedProduct">
  <xsl:copy>
    <xsl:apply-templates select="@*|*"/>
    <RelationType><xsl:value-of select="name(..)"/></RelationType>
  </xsl:copy>
</xsl:template>

Applying both gives you the exact result.
