Question

i have an XML generated in the below form from JSON to XML Conversion.

                  <double>18281.6</double>
                  <double>157.1095</double>
                  <double>136.4</double>
                  <double>156.73</double>

            <int>218</int>
         </entry>
      </linked-hash-map>
   </entry>
</linked-hash-map>

the below part needs to be converted in both the xmls.

<entry>
       <string>column_names</string>
        <list>
          <string>DATE</string>
          <string>VALUE</string>
        </list>
</entry>
     <entry>
            <string>data</string>
            <list>
              <list>
                <string>2016-07-01</string>
                <double>18675.3</double>
              </list>
              <list>
                <string>2016-04-01</string>
                <double>18450.1</double>
              </list>
             </list>
    </entry>

How to convert this into the below formats?

1.

  <entry>
       <Date>2016-07-01</Date>
            <Value>18675.3</Value>
        </entry>
        <entry>
            <Date>2016-04-01</Date>
            <Value>18450.1</Value>
         </entry>

2.

<entry>
    <Date>2016-07-01</Date>
    <Value>18675.3</Value>
    <Date>2016-04-01</Date>
    <Value>18450.1</Value>
    </entry>

Note: All the data(Date, Value,data,entry,etc) are dynamic here.

Looking for a generic implementation of XSLT to bring the desired output. if not possible with xslt, then would like to go for Java to convert this.

Any help would be greatly appreciated.``

Answer 1

The following stylesheet will work for both your examples. I don't think it needs to be any more generic than that - and if it does, I don't see how.

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/linked-hash-map">
    <xsl:variable name="col-names" select="entry/linked-hash-map/entry[string='column_names']/list/string" />
    <root>
        <xsl:for-each select="entry/linked-hash-map/entry[string='data']/list/list">
            <xsl:variable name="current-row" select="." />
            <entry>
                <xsl:for-each select="$col-names">
                    <xsl:variable name="i" select="position()" />
                    <xsl:element name="{.}">
                        <xsl:value-of select="$current-row/*[$i]" />
                    </xsl:element>
                </xsl:for-each>
            </entry>
        </xsl:for-each>
    </root>
</xsl:template>

</xsl:stylesheet>

As with your previous question , this assumes that the supplied column names are valid XML element names.
