How do you repeat rows with certain values but group on others

I am new to XSLT and have read/researched both the XSLT 2.0 and 1.0 versions and could use some assistance if figuring out how to get something accomplished.

I have the following XML file that has has months of repeating data 2 sets per month. I am needing to break the rows up so that each row only contains one pair of months data (Gross/Net sales values) but repeats for every set of month's data that is expressed.

Code:

<?xml version="1.0"?>
<?xml-stylesheet type="txt/xsl" href="transform.xsl"?>
<Report>
<ReportData>
<DataSet>
<Row rowNum="1">
<Column name="Title 1"><Val xsi:type="xsd:string">Sample 1</Val></Column>
<Column name="Title 2"><Val xsi:type="xsd:string">Sample 2</Val></Column>
<Column name="Title 3"><Val xsi:type="xsd:string">Sample 3</Val></Column>
<Column name="Title 4"><Val xsi:type="xsd:string">Sample 4</Val></Column>
<Column name="Title 5"><Val xsi:type="xsd:string">160X600</Val></Column>
<Column name="Title 6"><Val xsi:type="xsd:string" xsi:nil="true"></Val></Column>
<Column name="Title 7"><Val xsi:type="xsd:integer">1325600</Val></Column>
<Column name="MAR_Month_Total"><Val xsi:type="xsd:float">19.00</Val></Column>
<Column name="MAR_Month_Total_B"><Val xsi:type="xsd:float">22.00</Val></Column>
<Column name="APR_Month_Total"><Val xsi:type="xsd:float">18.00</Val></Column>
<Column name="APR_Month_Total_B"><Val xsi:type="xsd:float">35.00</Val></Column>
<Column name="MAY_Month_Total"><Val xsi:type="xsd:float">25.00</Val></Column>
<Column name="MAY_Month_Total_B"><Val xsi:type="xsd:float">15.00</Val></Column>
</Row>
</DataSet>
</ReportData>
</Report>

Sample of how the results need to turn out. New fields with Month ID is based on the month being represented and Year is always the current year.

Code:

<?xml version="1.0"?>
<?xml-stylesheet type="txt/xsl" href="transform.xsl"?>
<Report>
<ReportData>
<DataSet>
<Row rowNum="1">
<Column name="Title 1"><Val xsi:type="xsd:string">Sample 1</Val></Column>
<Column name="Title 2"><Val xsi:type="xsd:string">Sample 2</Val></Column>
<Column name="Title 3"><Val xsi:type="xsd:string">Sample 3</Val></Column>
<Column name="Title 4"><Val xsi:type="xsd:string">Sample 4</Val></Column>
<Column name="Title 5"><Val xsi:type="xsd:string">160X600</Val></Column>
<Column name="Title 6"><Val xsi:type="xsd:string" xsi:nil="true"></Val></Column>
<Column name="Title 7"><Val xsi:type="xsd:integer">1325600</Val></Column>
<Column name="MAR_Month_ID"><Val xsi:type="xsd:integer">3</Val></Column>
<Column name="YEAR"><Val xsi:type="xsd:integer">2012</Val></Column>
<Column name="MAR_Month_Total"><Val xsi:type="xsd:float">19.00</Val></Column>
<Column name="MAR_Month_Total_B"><Val xsi:type="xsd:float">22.00</Val></Column>
</Row>
<Row rowNum="2">
<Column name="Title 1"><Val xsi:type="xsd:string">Sample 1</Val></Column>
<Column name="Title 2"><Val xsi:type="xsd:string">Sample 2</Val></Column>
<Column name="Title 3"><Val xsi:type="xsd:string">Sample 3</Val></Column>
<Column name="Title 4"><Val xsi:type="xsd:string">Sample 4</Val></Column>
<Column name="Title 5"><Val xsi:type="xsd:string">160X600</Val></Column>
<Column name="Title 6"><Val xsi:type="xsd:string" xsi:nil="true"></Val></Column>
<Column name="Title 7"><Val xsi:type="xsd:integer">1325600</Val></Column>
<Column name="APR_Month_ID"><Val xsi:type="xsd:integer">4</Val></Column>
<Column name="YEAR"><Val xsi:type="xsd:integer">2012</Val></Column>
<Column name="APR_Month_Total"><Val xsi:type="xsd:float">18.00</Val></Column>
<Column name="APR_Month_Total_B"><Val xsi:type="xsd:float">35.00</Val></Column>
</Row>
<Row rowNum="3">
<Column name="Title 1"><Val xsi:type="xsd:string">Sample 1</Val></Column>
<Column name="Title 2"><Val xsi:type="xsd:string">Sample 2</Val></Column>
<Column name="Title 3"><Val xsi:type="xsd:string">Sample 3</Val></Column>
<Column name="Title 4"><Val xsi:type="xsd:string">Sample 4</Val></Column>
<Column name="Title 5"><Val xsi:type="xsd:string">160X600</Val></Column>
<Column name="Title 6"><Val xsi:type="xsd:string" xsi:nil="true"></Val></Column>
<Column name="Title 7"><Val xsi:type="xsd:integer">1325600</Val></Column>
<Column name="MAY_Month_ID"><Val xsi:type="xsd:integer">5</Val></Column>
<Column name="YEAR"><Val xsi:type="xsd:integer">2012</Val></Column>
<Column name="MAY_Month_Total"><Val xsi:type="xsd:float">25.00</Val></Column>
<Column name="MAY_Month_Total_B"><Val xsi:type="xsd:float">15.00</Val></Column>
</Row>
</DataSet>
</ReportData>
</Report>

Any Thoughts/Pointers would be totally appreciative.

I think I would tackle this with something like

Code:

<xsl:variable name="rows" select="//Row"/>
<xsl:for-each select="distinct-values(for $n in $rows/Column/@name return substring-before($n, '_Month_Total')[. != '']">
  <xsl:variable name="month"
  <Row>
     ... create row for month $month ...

Thank you so very much for the example. Gave me a much needed direction on where to go.
