If you're like me, then you enjoy playing with lots of textual data and scour the internet for sources of it.
mediawiki's dumps are a pretty awesome chunk that's fun to work with.
go get github.com/dustin/go-wikiparse
The parser takes any io.Reader as a source assuming it's a complete
XML dump and lets you pull wikiparse.Page objects out of it. These
typically arrive as bzip2 files, so I make my program open the file
and set up a bzip reader over it and all that. But you don't need to
do that if you want to read off of stdin. Here's a complete example
that emits page titles from a decompressing stream on stdin:
package main
import (
"fmt"
"os"
"github.com/dustin/go-wikiparse"
)
func main() {
p, err := wikiparse.NewParser(os.Stdin)
if err != nil {
fmt.Fprintf(os.Stderr, "Error setting up parser", err)
os.Exit(1)
}
for err == nil {
var page *wikiparse.Page
page, err = p.Next()
if err == nil {
fmt.Println(page.Title)
}
}
}
Example invocation:
bzcat enwiki-20120211-pages-articles.xml.bz2 | ./sample
Because it's interesting to me, I wrote a parser for the wikiproject geographical coordinates that are found on many pages. Use this on the page's content to find out if it's a place or not. Then go there.
