Hi there,
My XSLT processor is Saxon v.9. I have an xml file of a list of station names: stations.xml: <station_list>
<stations>
<station name="MONP">
<station name="MONP2">
<station name="PFO">
</stations>
<station_list>In another xml file I have a series of values associated with a particular station name (although now the tag is <datalogger>): dataloggers.xml: <dataloggerlist>
<datalogger name="MONP">
<con>sleeping</con>
<dlt>280594.003</dlt>
<rtm>-280553.133</rtm>
</datalogger>
<datalogger name="MONP2">
<con>sleeping</con>
<dlt>334455.003</dlt>
<rtm>-483940.133</rtm>
</datalogger>
<datalogger name="PFO">
<con>awake</con>
<dlt>111111.003</dlt>
<rtm>-222222.133</rtm>
</datalogger>
<dataloggerlist>These are in turn defined in a third xml file (so my xsl processor can convert more than one xml file at a time): feeder.xml: <?xml version="1.0" encoding="ISO-8859-1" ?>
<sources>
<source href="stations.xml" />
<source href="dataloggers.xml" />
</sources>I want to combine them together so that the output looks like the code below (Aside: I am aware that the station name could be retrieved from datalogger.xml <datalogger name="XXX">, however I am retrieving a whole suite of other information that is unique to stations.xml and not pertinent to this issue): output.xml: <Placemark> <name>MONP</name> <con>sleeping</con> <dlt>280594.003</dlt> <rtm>-280553.133</rtm> </Placemark> <Placemark> <name>MONP2</name> <con>sleeping</con> <dlt>334455.003</dlt> <rtm>-483940.133</rtm> </Placemark> <Placemark> <name>PFO</name> <con>awake</con> <dlt>111111.003</dlt> <rtm>-222222.133</rtm> </Placemark> Where name is derived from stations.xml. To get the con, dlt and rtm values from dataloggers.xml into output.xml I have done the following, although I am not sure this is close to being right: (1) Open up stations.xml, and using templates I get the value of the station name into a variable called $thisSta (2) Using the value of $thisSta, I then search for the datalogger tag that has a name attribute that matches $thisSta. (3) Now I have isolated the station I am interested in from dataloggers.xml I want to grab some values (con, dlt, rtm). snippet of convert.xsl where I am trying to achieve this: <xsl:template match="station"> <Placemark> <xsl:variable name="thisSta"><xsl:value-of select="@name" /></ xsl:variable> <name><xsl:value-of select="$thisSta" /></name> <xsl:template match="document( sources/source/@href, .)/ dataloggerlist/datalogger/@name=$thisSta"> <con><xsl:value-of select="con" /></con> <dlt><xsl:value-of select="dlt" /></dlt> <rtm><xsl:value-of select="rtm" /></rtm> </xsl:template> <Placemark> </xsl:template> When I try and process with Saxon, I get the following output: Error at xsl:template on line 102 of file:convert.xsl: XTSE0340: XSLT Pattern syntax error at char 0 on line 102 in {document( sources}: The only functions allowed in a pattern are id() and key() The error is the second template match statement. I think I am pretty close to getting this working, but I have run out of ideas. Can you do what I am trying to achieve, or is my XPath expression syntax just poorly written? Thanks in advance, - Rob
