How do you call a web site and parse the results returned?

[rleiman]

Hi Everyone,

I would like to call this web site with the following url:

http://where.yahooapis.com/geocode?q=131+stedman+st,+lowell,+ma

This will return the following XML results:

I would like to grab these:

<Error>0</Error>
<latitude>42.626317</latitude>
<longitude>-71.350338</longitude>

Do you have an example project that will grab a return XML file and look at particular XML tags?

Can you show me all the coding needed to do this using the HttpUtils library?

Please go easy on me since I'm still new to all of this.

Thanks.

Take a look at THIS post, it will show you how to parse an XML using the XMLSax library.

Hi NJDude,

Thanks for the reply and XMLSax.

Can you show me the code needed to call the url and download the result returned as an XML file so I can process it with XMLSax?

Thanks.

 

[NJDude]

Ok, this is a bare bones project which downloads the XML, parses it and displays the Latitude and Longitude in a MsgBox.

You need to have the XMLSax library.

Thanks.
