View Full Version : File downloading and XML parsing
October 23rd, 2011, 09:51 PM
Hello, I'm trying to write a program in C the requires me to download a XML file, parse it for data, and display parsed text from the file. What is the best way to do this? I cannot seem to find a way that makes sense. Thanks!

I don't know what you would do (or why) but if I wanted to parse XML, I'd probably start with this:
sudo apt-get libxml2-dev libxml2-doc
Then just look up the references in devhelp.

Well I'm trying to write a weather program, and the api for the website I'm using uses XML files, so I assumed I needed to parse them to get the information out of them. Unless there's a better way that I don't know about...

It's probably easier to parse than to download. See this if you need an example, I guess. http://xmlsoft.org/examples/parse1.c

gsmanners is right on the XML part, libxml is your friend here. To grab the data from the site, you can use libcurl
sudo apt-get install libcurl-dev
From what I remember when I was playing with it, libxml takes in a file pointer. Not sure if it's possible to give it an URL
