Extracting XML Tag Names

[Dave Elfers]

Hello, I need to get the tag name from an XML file. I know where it is going to be everytime, but I do not know what the name will be. This is a snippet of my xml data.

 
<Forecast>
 <Config/>
 <Date>THU SEP 9 2010</Date>
 <Time>4:53 PM CDT</Time>
<Thursday>
 <Conditions>Partly Cloudy</Conditions>
 <Description>Partly cloudy</Description>
 <Image>http://www.</Image>
 <High>68°F</High>
 <Low>50°F</Low>
 <Pop>0</Pop>
 </Thursday> 
 

I need to extract 'Thursday' from the tag to know what day the weather data is for. Tomorrow it will be Friday and so on and so forth. It will always be in the same place. I have tried this,

 
forecast_node = doc.getElementsByTagName('Forecast')
current_day = forecast_node[0].childNodes[4].tagName 

but it seems that I cannot use tagName in this manner. Any suggestions for me?

It seems that you want the fourth child element node of the Forecast node. To get that, you must skip the text nodes. Example:

xmlDoc = minidom.parseString(xmlStr)
forecast_node = xmlDoc.getElementsByTagName('Forecast')
 
# get 4th element node
count = 0
for child in forecast_node[0].childNodes:
    if child.nodeType == 1:
        count += 1
        if count == 4:
            break
print child

Thanks for pointing me this way, I am very new to this and never would have thought of it. Had to to change to

print child.toxml

to get the tag name completely out of the dom element. Thanks again!
