Hi Martin
I am using the code snippet you provided, along with the row to output the
time. But this doesn't seem to work.
The only thing I changed was to remove the template definition and added
Chart-Data before Root.
I get an error XML Parsing Error: no element found
I am complete newbie, so please let me know if I have to use template
definition and how to use it.
<xsl:key name="k1" match="Metrics/*" use="local-name()"/>
<chart_data>
<!-- Category (X axis) date row -->
<row>
<null/>
<xsl:for-each select="Chart-Data/Root/Item[position()=1]/Statistics/Item">
<string><xsl:value-of select="@StartRawDateAndTime"/></string>
</xsl:for-each>
</row>
<xsl:for-each select="Chart-Data/Root/Item/Statistics/Item[1]/Metrics/*">
<row>
<string><xsl:value-of select="local-name()"/></string>
<xsl:for-each select="key('k1', local-name())">
<number><xsl:value-of select="number(@TotalValue)"/></number>
</xsl:for-each>
</row>
</xsl:for-each>
</chart_data>

I need help to transform the XML data to plot a graph.
The metrics data has to be pulled outside and organized by Time.
The Metric Counter names (CPU, Disk, Memory) are dynamic, I mean, I could get
five metrics next time.
Please tell me how to pull data by the Names and organize by Time.
<Chart-Data> <Root> <Item ID="Server"> <Statistics > <Item
Time="1253419200000"> <Metrics> <CPU
TotalValue="20.0"/ > <Disk TotalValue="10.0" / >
<Memory TotalValue="20.0" / > </Metrics > </Item >
<Item Time="1253419211000"> <Metrics> <CPU
TotalValue="40.0"/ > <Disk TotalValue="60.0" / >
<Memory TotalValue="10.0" / > </Metrics > </Item >
</Statistics> </Item> </Root> <Chart-Data>
This has to be Transformed in this XSL output
<chart_data> <row> <null/>
<string>10</string> <string>11</string>
</row>
I don't understand where above 'row' comes from.
<row> <string>CPU</string>
<number >20</number> <number
40</number> </row> <row>
<string>Memory</string> <number>20</number>
<number >10</number> </row>
<row> <string>Disk</string>
<number >10</number> <number>60</number>
</row> </chart_data>
And I don't see where data is organized by time. So based on that all I can
suggest is
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output indent="yes"/>
<xsl:key name="k1" match="Metrics/*" use="local-name()"/>
<xsl:template match="Chart-Data">
<chart_data>
<xsl:for-each select="Root/Item/Statistics/Item[1]/Metrics/*">
<row>
<string><xsl:value-of select="local-name()"/></string>
<xsl:for-each select="key('k1', local-name())">
<number><xsl:value-of select="number(@TotalValue)"/></number>
</xsl:for-each>
</row>
</xsl:for-each>
</chart_data>
</xsl:template>
</xsl:stylesheet>
which outputs
<chart_data>
<row>
<string>CPU</string>
<number>20</number>
<number>40</number>
</row>
<row>
<string>Disk</string>
<number>10</number>
<number>60</number>
</row>
<row>
<string>Memory</string>
<number>20</number>
<number>10</number>
</row>
</chart_data>
which is what you described above, with the exception of the first 'row'
element in your described output, as I can't relate that to input data.
