Objective:

To generate a 5-day forecast for a given set of GPS coordinates, by communicating with a web service coded in WSDL (Web Service Description Language) to retrieve information by means of sending a SOAP (Simple Object Access Protocol) client message, invoking one of the server's functions to obtain information.

Input:

• XML request containing a SOAP message which inputs appropriate information to the web service as required.

Output:

• XML response containing a SOAP message with values of appropriate requested parameters.

• XSLT table for the Web service method derived from the SOAP response message.

Specification:

• The SOAP message requests information from the National Digital Forecast Database (NDFD) Web Service at:
https://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl by specifying the appropriate parameters for the method:

• Use either: (i) the SOAP message generator: https://www.soapclient.com/soapmsg.html, or (ii) the SOAPui application (in the lab or downloaded from https://soapui.orgto a home computer) to generate a template SOAP message based on the above WSDL file and the NDFDgenByDay method, then fill in the placeholders between the appropriate XML tags before executing to generate a response SOAP message.

• Use the XSLT display editor to display each appropriate table by replacing the XML and XSLT code:
https://www.w3schools.com/xsl/tryxslt.asp?xmlfile=cdcatalog&xsltfile=cdcatalog. Note: this requires stripping off (i) everything before the <data> tag; (ii) the <moreWeatherInformation>...</moreWeatherInformation> tags and values

(the "&" causes trouble); (iii) everything after the </data>tag. This makes <data> the root element in the XML file.

• Hint: to get the value of an attribute, use <xsl:value of select="path to tag/@name_of_attribute/>

• Hint: to select a particular set of times, filter the selection, use <xsl:for-each select="data/time-layout[layout-key='...']">, replacing ... with the value of the element layout-key

• To display an image in XSLT, use <img><xsl:attribute name="src"><xsl:value-of select="URL"/></xsl:attribute>where URL represents the appropriate hyperlink.

• To force a newline, one way is to create a blank table: <table><tr></tr></table>, repeating for each blank line desired.

What to turn in:

• A zipped file (tech2_yourlastname.zip) containing both the modified XML code (tech2_yourlastname.xml) generated from the SOAP response method and the XSLT code (tech2_yourlastname.xsl) submitted via Moodle to the appropriate lab section.
