Hello, the XML below is a sharply simplified version of Memphis weather
data available from the National Weather Service's SOAP web service[1].
<dwml version="1.0">
<data>
<time-layout time-coordinate="local" summarization="none">
<layout-key>k-p24h-n7-1</layout-key>
<start-valid-time period-name="Tomorrow"/> <!-- Thursday -->
<start-valid-time period-name="Friday"/>
<start-valid-time period-name="Saturday"/>
<start-valid-time period-name="Sunday"/>
<start-valid-time period-name="Monday"/>
<start-valid-time period-name="Tuesday"/>
<start-valid-time period-name="Wednesday"/>
</time-layout>
<time-layout time-coordinate="local" summarization="none">
<layout-key>k-p24h-n7-2</layout-key>
<start-valid-time period-name="Tonight"/> <--- Wed. night -->
<start-valid-time period-name="Tomorrow Night/>
<start-valid-time period-name="Friday Night"/>
<start-valid-time period-name="Saturday Night"/>
<start-valid-time period-name="Sunday Night"/>
<start-valid-time period-name="Monday Night"/>
<start-valid-time period-name="Tuesday Night"/>
</time-layout>
<parameters applicable-location="point1">
<temperature type="maximum" units="Fahrenheit"
time-layout="k-p24h-n7-1">
<name>Daily Maximum Temperature</name>
<value>65</value>
<value>66</value>
<value>68</value>
<value>71</value>
<value>72</value>
<value>63</value>
<value>60</value>
</temperature>
<temperature type="minimum" units="Fahrenheit"
time-layout="k-p24h-n7-2">
<name>Daily Minimum Temperature</name>
<value>55</value>
<value>44</value>
<value>44</value>
<value>46</value>
<value>50</value>
<value>49</value>
<value>41</value>
</temperature>
</parameters>
</data>
</dwml>
With this data, I would like to create a simple listing as follows:
Daily Maximum Temperatures:
-----------------------
Tomorrow: 65
Friday: 66
Saturday: 68
...
Daily Minimum Temperatures:
------------------------
Tonight: 55
Tomorrow Night: 44
Friday Night: 44
...
Note that, in the XML data, the blocks of time-layouts are tied to the
Max. and Min. temps below via the layout-key element / time-layout
attribute combination.
I guess my questions are
(1) how can I tie the time-layout elements and temperature elements
together using XSLT 1.0 using the layout-key
and
(2) how can I tie each period-name to its corresponding position with
the temperatures that it is associated with
In other words, how can I create my table above?
Thanks,
Glen
