Re: [xsl] complicacy of sorting

[Joerg Heinicke <joerg.heinicke@xxxxxx>]

Hello Evgenia,

your code looks ok, so there is no obvious error. Maybe you can show us 
the according XML structure? And what's $isid? And what processor are 
you using? Some have problems with current() in some cases (MSXML if I 
recall correctly).

Furthermore you can use keys to get something like [@id = 
current()/@idref]. So in you case it would look like the following:

<xsl:key name="MPCs" match="MonthPriceCountryList/MonthPriceCountry" 
use="@CountryID"/>

This will shorten the rest of the code:

<xsl:for-each select="CountryList/Country">
  <xsl:sort select="key('MPCs', @ID)[@IStationID = $isid]/@Price"
            order="ascending"/>
  <xsl:if test="position() = 1">
    <xsl:value-of select="key('MPCs', @ID)[@IStationID = $isid]/@Price"/>
  </xsl:if>
</xsl:for-each>

This shell be at least more efficient, but it's the same logic. If 
current() is not the reason, this won't help you neither.

Regards,

Joerg
