SWXMLHash can't parse a [XMLIndexer] - swift

Question

I am trying for first time to parse a XML file and I am using SWXMLHash.
My xml file is:
<weatherdata xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://api.met.no/weatherapi/locationforecast/1.9/schema" created="2018-02-13T18:12:31Z">
<meta>
<model name="LOCAL" termin="2018-02-13T12:00:00Z" runended="2018-02-13T14:27:32Z" nextrun="2018-02-13T22:00:00Z" from="2018-02-13T19:00:00Z" to="2018-02-16T06:00:00Z" />
<model name="EPS" termin="2018-02-13T00:00:00Z" runended="2018-02-13T09:03:05Z" nextrun="2018-02-13T22:00:00Z" from="2018-02-16T12:00:00Z" to="2018-02-22T18:00:00Z" />
</meta>
<product class="pointData">
<time datatype="forecast" from="2018-02-13T19:00:00Z" to="2018-02-13T19:00:00Z">
<location altitude="0" latitude="" longitude="">
<temperature id="TTT" unit="celsius" value="3.5"/>
<windDirection id="dd" deg="158.8" name="S"/>
<windSpeed id="ff" mps="8.8" beaufort="5" name="Frisk bris"/>
<windGust id="ff_gust" mps="15.0"/>
<areaMaxWindSpeed mps="13.8"/>
<humidity value="82.1" unit="percent"/>
<pressure id="pr" unit="hPa" value="1002.5"/>
<cloudiness id="NN" percent="99.3"/>
<fog id="FOG" percent="0.0"/>
<lowClouds id="LOW" percent="73.2"/>
<mediumClouds id="MEDIUM" percent="0.0"/>
<highClouds id="HIGH" percent="91.0"/>
<dewpointTemperature id="TD" unit="celsius" value="0.6"/>
</location>
</time>
The <time> </time> repeates.
Having made a let parsedResultXML = SWXMLHash.parse(data)
I am trying to parse with a for in loop
for node in parsedResultXML["weatherdata"]["product"]["time"].all{
print(node)
}
I get results
<time to="2018-02-14T01:00:00Z" from="2018-02-14T01:00:00Z" datatype="forecast">
<location latitude="" longitude="" altitude="0">
<temperature id="TTT" unit="celsius" value="3.4"></temperature>
<windDirection id="dd" name="S" deg="158.7"></windDirection>
<windSpeed name="Liten kuling" mps="11.1" id="ff" beaufort="6"></windSpeed>
<windGust id="ff_gust" mps="19.0"></windGust>
<areaMaxWindSpeed mps="17.5"></areaMaxWindSpeed>
<humidity unit="percent" value="88.3"></humidity>
<pressure id="pr" unit="hPa" value="1002.5"></pressure>
<cloudiness id="NN" percent="99.3"></cloudiness>
<fog id="FOG" percent="0.1"></fog>
<lowClouds id="LOW" percent="98.6"></lowClouds>
<mediumClouds id="MEDIUM" percent="93.4"></mediumClouds>
<highClouds id="HIGH" percent="57.8"></highClouds>
<dewpointTemperature id="TD" unit="celsius" value="1.5"></dewpointTemperature>
</location>
</time>
But I can't access the elements.
Using
for node in parsedResultXML["weatherdata"]["product"]["time"].all{
node["time"].element?.attribute(by: "from")?.text
}
I don't get any results back.
Any idea??
Thanks

You're close... as #rmaddy commented, node is already indexed to "time". So instead of:
for node in parsedResultXML["weatherdata"]["product"]["time"].all {
node["time"].element?.attribute(by: "from")?.text
}
Do this instead:
for node in parsedResultXML["weatherdata"]["product"]["time"].all {
node.element?.attribute(by: "from")?.text
}
