Hi guys,

I have this code...

<xsl:variable name="codice" select="SegmentList/Segment/Destination/Code"/>
<xsl:value-of select="/CommandList/CheckRouting/Summary/Destination/AirportList/Airport/Code[.='{$codice}']/preceding-sibling::Name[1]" />

In this way nothing is displayed

but if I put manually
<xsl:variable name="codice" select="SegmentList/Segment/Destination/Code"/>
<xsl:value-of select="/CommandList/CheckRouting/Summary/Destination/AirportList/Airport/Code[.='LGW']/preceding-sibling::Name[1]" />

I get displayed all the informations.

The variable codice is not empty if I print it it is displayed.

Could you give me some advices ?

Regards.

Have you tried:

<xsl:value-of select="/CommandList/CheckRouting/Summary/Destination/AirportList/Airport/Code[.=$codice]/preceding-sibling::Name[1]" />

Yes it works but the results is equal for each row.

For example, if $codice is BCN
the select give me always "BArajas"

Perhaps the variable "codice" must be clean after after print the results ?

Not sure what behavior you are looking for... we would need more details about how that code is being used in your overall XSLT and what you are trying to do.

</CommandList>

I use this command to inizilize the list

<xsl:for-each select="/CommandList/CheckRouting/RouterList/Router/GroupList/Group/OutwardList/Outward" >

inside this cycle I Must check the
"SegmentList/Segment/Destination/Code"
for example "FCO" and get the relative Airport name from the summary area...

so I thought to use this

<xsl:variable name="codice" select="SegmentList/Segment/Destination/Code"/>
<xsl:value-of select="$codice" />
<xsl:value-of select="/CommandList/CheckRouting/Summary/Destination/AirportList/Airport/Code[.=$codice]/preceding-sibling::Name[1]" />

But it doesnt works.
Be careful becouse the router list could be more then one.
I hope you could help me...
Thanks a lot.

I guess the problem is that each entry can have multiple segments; so, your variable defined as:
<xsl:variable name="codice" select="SegmentList/Segment/Destination/Code"/>

...ends up being a nodeset made of multiple elements. Not sure which segment you need to match, but, for example, if you want to match the first one, you can do:

<xsl:for-each select="/CommandList/CheckRouting/RouterList/Router/GroupList/Group/OutwardList/Outward" >
<xsl:variable name="codice" select="SegmentList/Segment[1]/Destination/Code/text()"/>
<xsl:value-of select="$codice" />
<xsl:value-of select="//Airport[Code=$codice]/Name"/>
</xsl:for-each>

Note that if the Summary section doesn't has an Airport entry for a Code, the last value-of will return nothing.

<xsl:value-of select="Airport[Code='FCO']/Name"/>
I could see displayed, the value...

I really dont understand.
This is the code that I'm using now inside the loop.

<xsl:variable name="codice" select="SegmentList/Segment[1]/Destination/Code/text()"/>
<xsl:value-of select="$codice" />
<xsl:value-of select="Airport[Code=$codice]/Name"/>

If you see nothing out of <xsl:value-of select="//Airport[Code=$codice]/Name"/> (I am assuming you forgot // before Airport?) it means that there is no $codice equivalent in the list of Airport codes/names.

For example, in the small fragment you have posted, you have VIE as airport code that has no equivalent in the summary section, so the value-of above won't return anything.

I'm sorry, it works.
There arent the right pair Of Iata Code in xml for comparing.

Now I need only to add a control able to write something if the code is not in the xml.

It's possible to use choose ?

Thanks a lot.

It sure is...

<xsl:choose>
<xsl:when test="//Airport[Code=$codice]/Name">
<xsl:value-of select="//Airport[Code=$codice]/Name"/>
</xsl:when>
<xsl:otherwise>Sigh...</xsl:otherwise>
</xsl:choose>
