Often web services reply with a XML document specific to the web service.
IYOPRO supports the parsing of these XML replies. The C# XML processing can be used to easily process a XML reply.
Example:
Assume the reply from the web service is a XML document like this:
<?xml version="1.0" encoding="utf-16"?>
<CurrentWeather>
<Location>Hamburg-Finkenwerder, Germany (EDHI) 53-32N 009-50E 13M</Location>
<Time>Jun 27, 2016 - 08:50 AM EDT / 2016.06.27 1250 UTC</Time>
<Wind> from the SSW (210 degrees) at 14 MPH (12 KT) (direction variable):0</Wind>
<Visibility> greater than 7 mile(s):0</Visibility>
<SkyConditions> mostly cloudy</SkyConditions>
<Temperature> 69 F (21 C)</Temperature>
<DewPoint> 51 F (11 C)</DewPoint>
<RelativeHumidity> 52%</RelativeHumidity>
<Pressure> 29.97 in. Hg (1015 hPa)</Pressure>
<Status>Success</Status>
</CurrentWeather>
However you are only interested in the relative humidity. Using the C# XML processing one can obtain the value e.g. like this:
import clr
clr.AddReference('System.Xml')
from System.Xml import XmlDocument
xmlDoc = XmlDocument()
xmlDoc.LoadXml(Value)
nodes = xmlDoc.SelectNodes("/CurrentWeather/RelativeHumidity")
for node in nodes:
Result = node.InnerText
break
It is also possible and often easier to use the XML 2 Linq approach to optain the value:
import clr
clr.AddReference('System.Xml.Linq')
from System.Xml.Linq import XElement
xmlElement = XElement.Parse(Value)
Result = xmlElement.Element("RelativeHumidity").Value
