Default Adding Distinct Values 1.0

Hey all,

I have requirement, on the basis of indicator = 'TL' I have to pick CoverageName and Limit and add the amounts of similiar coverages. Is there any way I could do that.

Here's xml:

<Policy>
<Vehicle id="v1">
<Coverage>
<CoverageName>ABC</CoverageName>
<CoverageLimit>Upto 50,000</CoverageLimit>
<CoverageAmount>100</CoverageAmount>
<Indicator>TL</Indicator>
</Coverage>
<Coverage>
<CoverageName>EFG</CoverageName>
<CoverageLimit>Upto 50,000</CoverageLimit>
<CoverageAmount>50</CoverageAmount>
<Indicator></Indicator>
</Coverage>
<Coverage>
<CoverageName>HIJ</CoverageName>
<CoverageLimit>Upto 10,000</CoverageLimit>
<CoverageAmount>20</CoverageAmount>
<Indicator></Indicator>
</Coverage>
<Coverage>
<CoverageName>KLM</CoverageName>
<CoverageLimit>Upto 100,000</CoverageLimit>
<CoverageAmount>10</CoverageAmount>
<Indicator>TL</Indicator>
</Coverage>
</Vehicle>
<Vehicle id="v2">
<Coverage>
<CoverageName>ABC</CoverageName>
<CoverageLimit>Upto 50,000</CoverageLimit>
<CoverageAmount>100</CoverageAmount>
<Indicator>TL</Indicator>
</Coverage>
<Coverage>
<CoverageName>EFG</CoverageName>
<CoverageLimit>Upto 50,000</CoverageLimit>
<CoverageAmount>50</CoverageAmount>
<Indicator></Indicator>
</Coverage>
<Coverage>
<CoverageName>HIJ</CoverageName>
<CoverageLimit>Upto 10,000</CoverageLimit>
<CoverageAmount>20</CoverageAmount>
<Indicator></Indicator>
</Coverage>
<Coverage>
<CoverageName>KLM</CoverageName>
<CoverageLimit>Upto 100,000</CoverageLimit>
<CoverageAmount>10</CoverageAmount>
<Indicator>TL</Indicator>
</Coverage></Vehicle>
<Vehicle id="v3">
<Coverage>
<CoverageName>ABC</CoverageName>
<CoverageLimit>Upto 50,000</CoverageLimit>
<CoverageAmount>100</CoverageAmount>
<Indicator>TL</Indicator>
</Coverage>
<Coverage>
<CoverageName>EFG</CoverageName>
<CoverageLimit>Upto 50,000</CoverageLimit>
<CoverageAmount>50</CoverageAmount>
<Indicator></Indicator>
</Coverage>
<Coverage>
<CoverageName>HIJ</CoverageName>
<CoverageLimit>Upto 10,000</CoverageLimit>
<CoverageAmount>20</CoverageAmount>
<Indicator></Indicator>
</Coverage>
<Coverage>
<CoverageName>KLM</CoverageName>
<CoverageLimit>Upto 100,000</CoverageLimit>
<CoverageAmount>10</CoverageAmount>
<Indicator>TL</Indicator>
</Coverage>
</Vehicle>
</Policy>


The output I want is in three columns



ABC Upto 50,000 300
KLM Upto 100,000 30


Thankx in advance

It's a standard grouping problem. Either move to XSLT 2.0 and use xsl:for-each-group, or learn about Muenchian grouping in XSLT 1.0 (which is quite tricky)
