在循环中获取关键列+ XSLT

Question

I need a help on getting primary key values repeated times from the xml.Here is the xml file.

<?xml version="1.0" encoding="UTF-8"?>
<request id="test">
<dataSets>
 <dataSet name="dim_table" friendlyName="dim" tableType="DIM">
 <fields>
  <field name="customer_id" dataType="varchar" primaryKey="true"/>
  <field name="customer_name" dataType="VARCHAR" primaryKey="false"/>
  <field name="customer_address" dataType="CHAR" primaryKey="false"/>
 </fields>
 </dataSet>
</dataSets>
</request>

the required output is

KeycolumnName,Columnname
customer_id,customer_id
customer_id,customer_name
customer_id,customer_address

Can anyone help me on this?

Answer 1

XML formatting is needed for a full answer, but:

<xsl:template match="/dataSets/dataSet/fields">
    <xsl:for-each select="field">
        <xsl:value-of select="@name" />
    </xsl:for-each>
</xsl:template>

(example code not tested)

Use XPath to define the content of the "select" attributes.

Answer 2

Updated code (previous answer couldn't handle this much new code):

This code works for me:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
        <xsl:for-each select="//dataSet">
            <xsl:for-each select="fields/field">
                KeyColumnName="<xsl:value-of select="../field[@primaryKey='true']/@name" />" ColumnName="bar <xsl:value-of select="@name" />"
            </xsl:for-each>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>
