change xslt to match all OSM tags in a GIS-file

Hello and good day dear friends

I am brandnew to GIS-Things, so please bear with me for asking a newbie question. I have an xslt that works on a split osm file[germany.osm.bz2]

i took the file called germany.osm.bz2 from this site: http://ftp5.gwdg.de/pub/misc/openstreetmap/download.geofabrik.de/ Apparently, right now, i am not at home so i cannot give you a smaller piece of this large file. Note: i splitted it with XML_Split Regarding the expected output - i want to have ALL (!!) Nodes and data that are combined with the term restaurant... HTH - (End of update.)

I am divin into the GIS-world with a headstart: As a example i I want to do is parse all elements of 'amenity' and @v='restaurant.

i visited the Doku for XAPI on Openstreetmap here: http://wiki.openstreetmap.org/wiki/Xapi

Here ive found a little example to show a map with marker (with XSL Code): http://wiki.openstreetmap.org/wiki/OpenLayers_Marker

Note: this is only an example: i guess if i can do this with one 'amenity'` - called restaurant then i can do it with others too.

My first trial: What i am currently ironing out: i have a xslt-processor that runs and gives back some results..: In other words i want to gather all "available" elements (nodes, ways and relations) to match the elements I need to rework the given filter below so that we can get all elements.... See the current XSLT - and see where i stuck..

<xsl:stylesheet version = '1.0'
        xmlns="http://www.w3.org/1999/xhtml"
        xmlns:xml_split="http://xmltwig.com/xml_split"
        xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>

    <xsl:output method="text" encoding="UTF-8"/>
    <xsl:template match="/">

            <xsl:for-each select="xml_split:root/node/tag[@k='amenity' and @v='restaurant']">
            <xsl:value-of select="../@id"/>
            <xsl:text>&#x09;</xsl:text>
            <xsl:value-of select="../@lat"/>
            <xsl:text>&#x09;</xsl:text>
            <xsl:value-of select="../@lon"/>
            <xsl:text>&#x09;</xsl:text>
            <xsl:for-each select="../tag[@k='name']">
                <xsl:value-of select="@v"/>
            </xsl:for-each>
            <xsl:text>&#x0A;</xsl:text>
        </xsl:for-each>
    </xsl:template>

</xsl:stylesheet>

it gives back the following results and now you see where i stuck...:

"27376049   49.6499423  8.5543447   Clubhaus SC Olympia Lorsch"
"27407910   49.7045590  8.5115993   Forsthaus Jägersburg"
"27433397   51.4588114  7.0073003   Unperfekthaus"
"27433643   50.0081188  9.0691993   Schützenhaus"
"27453754   49.6358087  8.4547972   Feldschlössel"
"27474067   50.1880211  9.1742722   Pizzeria A66"
"27475403   49.0062148  8.3369945   Marty's Restaurant"
"27505752   48.4081456  11.7959129  Gasthof Nagerl"
"27530181   49.5054702  8.7089191   Zum Pflug"

I want to have a more in depth results with all tags. What modifications do I need to make to the xslt-file?

I hope that I was able to ask the question correctly. If you have any questions do not hesitate to ask..
