Hi all,
this is my first post in this mailing group. I hope that anyboby could
help me parsing a xml file.
I found this website http://www.omegahat.org/RSXML/gettingStarted.html
but unfortunately my XML file is not as easy as the one in the example.
Example:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="http://werdis.dwd.de/css/UNIDART/climateTimeseriesOrderByStation.xsl
" type="text/xsl"?>
<data xmlns="http://www.unidart.eu/xsd";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.unidart.eu/xsd
http://werdis.dwd.de/conf/timeseriesExchangeType.xsd";>
<stationname value="Aachen">
<v date="2011-04-01" qualityLevel="high" latitude="50.7839"
longitude="6.0947" altitude="202" unitA="m" geoQualityLevel="certain"
unitV="degree C">14.1</v>
<v date="2011-04-02">17.6</v>
<v date="2011-04-03">11.5</v>
<v date="2011-04-04">10.0</v>
<v date="2011-04-05" qualityLevel="low">9.6</v>
<v date="2011-04-06">16.0</v>
</stationname>
<stationname value="Ahaus">
<v date="2011-04-01" qualityLevel="high" latitude="52.0828"
longitude="6.9417" altitude="45.5" unitA="m" geoQualityLevel="certain"
unitV="degree C">12.5</v>
<v date="2011-04-02">15.9</v>
<v date="2011-04-03">12.0</v>
<v date="2011-04-04">10.1</v>
<v date="2011-04-05">8.8</v>
<v date="2011-04-06">13.5</v>
</stationname>
</data>
I would like to get a table in R like this:
stationname date value
Aachen 2011-04-01 14.1
Aachen 2011-04-01 17.6
.
.
.
Ahaus 2011-04-06 13.5
I tried to do this:
doc = xmlRoot(xmlTreeParse("de.dwd.klis.TADM.xml"))
tmp = xmlSApply(doc, function(x) xmlSApply(x, xmlValue))
but the stationname was not parsed because "Aachen" is kind of
attribute of stationname.
Could anyone give some help?
Thanks,
kai.
