I have an XML document and I am trying to use XSLT to convert it into a KML document (to use on Google Earth). Here is a small part of my XML document :

What I am unable to achieve/comprehend is selecting each nodes in rtc/trajets (metrobus,lebus,expressbus,couchetard). The problem is cannot do for each (rtc/trajets/elementX) because elementX has a different name everytime. The file is very large so i didn't copy it entirely basically the structure is as follows (should have made a XML schema...) rtc>trajets>metrobus,lebus,expressbus,couchetard>bus-trajets(all the bus lines for this categorie of bus)>coordinates of this bus line.
Here is what I've done so far in XSL
<?xml version="1.0" encoding="utf-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" encoding="utf-8" />
<xsl:template match="/">
<kml xmlns="http://www.opengis.net/kml/2.2"
xmlns:gx="http://www.google.com/kml/ext/2.2">
<Document>
<Placemark>
<LineString>
<xsl:for-each select="bus-trajet">
<Coordinates>
<xsl:for-each select="coordonnee">
<xsl:value-of select="long"/> , <xsl:value-of select="lat"/>
</xsl:for-each>
</Coordinates>
</xsl:for-each>
</LineString>
<Style>
<LineStyle>
<color></color>
</LineStyle>
<LabelStyle>
<color></color>
</LabelStyle>
</Style>
</Placemark>
</Document>
</kml>
</xsl:template>
</xsl:stylesheet>
I'm also confused as to how to created a structure that can accommodate the category of the bus because after the tag it's directly a placemark(line of the bus with its coordinates).
Any help appreciated and sorry if half the code is in french...
At the moment you have this xsl:for-each
<xsl:for-each select="/bus-trajet">
But this is currently not achieving much because at the point you are positioned on the document node (due to the template match of /) so it is looking for a root element called bus-trajet.
Now, what you could do is this...
<xsl:for-each select="/rtc/trajets/*/bus-trajet">
Note the use of * which will match any element. If you wanted to match only a subset of elements, you could do this...
<xsl:for-each select="/rtc/trajets/*[self::metrobus or self::lebus]/bus-trajet">
Alternatively, you could do this, which would match bus-traject at any level
<xsl:for-each select="//bus-trajet">
As a side note, you are doing this to get the co-ordinates...
<xsl:value-of select="long"/> , <xsl:value-of select="lat"/>
But it should be the following, as long and lat are attributes
<xsl:value-of select="@long"/> , <xsl:value-of select="@lat"/>
