Sorry for not being clear.
I'm working on a XSLT for X3D, and this node deals with x,y,z
co-ordinates within such a 3d world, derived from
<Work_Location_longitude>, <Work_Location_latitude>, and <Work_Year>
respectively - each of which are elements in the XML source file.
Here's an edited version of the source XML:
/////
<?xml version="1.0" encoding="iso-8859-1" ?> <?xml-stylesheet
type="text/xsl" href="X3D-XSLT_Work_Year.xsl"?>
<works>
<work>
<Work_Year>1981</Work_Year>
<Work_Name>Rainfall at Launching Place</Work_Name>
<Work_Location>Australia</Work_Location>
<Work_Location_longitude>133</Work_Location_longitude>
<Work_Location_latitude>-27</Work_Location_latitude>
</work>
<work>
<Work_Year>1981</Work_Year>
<Work_Name>A Walk Through the City</Work_Name>
<Work_Location>Canada</Work_Location>
<Work_Location_longitude>-95</Work_Location_longitude>
<Work_Location_latitude>60</Work_Location_latitude>
</work>
<work>
<Work_Year>1981</Work_Year>
<Work_Name>Five Silent Studies</Work_Name>
<Work_Location>Canada</Work_Location>
<Work_Location_longitude>-95</Work_Location_longitude>
<Work_Location_latitude>60</Work_Location_latitude>
</work>
etc
etc
<works>
/////
I want to get the <Work_Location_longitude> values for each record, -1.4
from this, and if there are previous records, offset each of the
subsequent results by 5. This will determine the x value of the node
position.
Similarly,
I want to get the <Work_Location_latitude> values for each record, -2.2
from this, and if there are previous records, offset each of the
subsequent results by 5. This will determine the y value of the node
position.
Here's the XSLT (shortened version)
/////
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output media-type="model/x3d=xml"
doctype-system="http://www.web3d.org/specifications/x3d-3.2.dtd";
method="xml" encoding="UTF-8" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="/">
<X3D profile="Immersive">
<head> <title/></head>
<Scene>
<xsl:apply-templates/>
</Scene>
</X3D>
</xsl:template>
<xsl:template match="works">
<Group>
<xsl:for-each select="work">
<Group>
<Transform translation='0 0 0'> /<!-- i.e the x,y,z co-ords
for the node>/
<xsl:attribute name="translation">
<xsl:value-of select="Work_Location_longitude"/>/ <!-- get this value-of
select, -1.4, and add 5 if there is a previous record with the same
value value-of select "Work_Location_longitude">/
<xsl:value-of select="Work_Location_latitude"/>/<!-- get this value-of
select, -2.2, and add 5 if there is a previous record with the same
value-of select "Work_Location_latitude">/
<xsl:value-of select="Work_Year div 10"/></xsl:attribute>
<Shape>
<Appearance>
<Material />
</Appearance>
<xsl:element name="Text"><xsl:attribute name="string"> <xsl:value-of
select="Work_Year"/> </xsl:attribute> </xsl:element>
</Shape>
</Transform>
</Group>
</xsl:for-each>
</Group>
etc
etc
etc
</xsl:template>
</xsl:stylesheet>
/////
And the output i want would be something like this:
/////
<!DOCTYPE X3D SYSTEM "http://www.web3d.org/specifications/x3d-3.2.dtd";>
<X3D profile="Immersive">
<head>
<title/>
</head>
<Scene>
<Group>
<Group>
<Transform translation="*131.6 -29.2 198.1*"> /<!-- i.e longitude -1.4,
latitude -2.2, year / 10>/
<Shape>
<Appearance>
<Material/>
</Appearance>
<Text string=""Rainfall at Launching Place""></Text>
<!-- Text string="Australia"></Text> -->
</Shape>
</Transform>
</Group>
<Group>
<Transform translation="*-93.6 57.8 198.1*"> /<!-- i.e longitude -1.4,
latitude -2.2, year / 10>/
<Shape>
<Appearance>
<Material/>
</Appearance>
<Text string="A Walk Through the City"></Text>
<!-- <Text string="Canada"></Text> -->
</Shape>
</Transform>
</Group>
<Group>
<Transform translation="*-88.6 62.8 198.1*"> /<!-- i.e longitude -1.4
+5, latitude -2.2 +5, year / 10>/
<Shape>
<Appearance>
<Material/>
</Appearance>
<Text string="Five Silent Studies"></Text>
<!-- <Text string="Canada"></Text> -->
</Shape>
</Transform>
</Group>
etc
etc
</Group>
</Scene>
</X3D>

Can anyone shed any light on this?
