Scraper for the dog registry in Plovdiv, Bulgaria
1. Open http://registry.plovdiv.bg/eDogs/default.aspx
2. Select 50 entries per page
3. Copy JS in console and run
4. Back up the downloaded data file
5. Extract all addresses:
awk -F '\t' '{print $4}' plddogs.tsv | grep -v address | sed 's_,\? \?\(ет\|ап\)\.\? \?[0-9]\+ \?__g;s_ \?№ \?_ _' |sort -u > addr
6. Geotag the addresses:
php geotag.php addr > addrg
7. Merge geotagged addresses with scaraped data and exclude columns:
for i in `sed 's_\t_|_g;s_ _\__g' plddogs.tsv | grep -v address`;
do c=`echo $i | sed 's_\__ _g'`;
echo -n `echo $c | awk -F '|' '{print $1","$2","$5","$6","}'`;
a=`echo $c | awk -F '|' '{print $4}'| sed 's_,\? \?\(ет\|ап\)\.\? \?[0-9]\+ \?__g;s_ \?№ \?_ _'`;
grep -m 1 "^$a" addrg | sed 's_.*\t__';
done > data.csv
8. Cleanup extracted report:
sed -i 's_\([0-9]\{2\}\)\.\([0-9]\{2\}\)\.\([0-9]\{4\}\) г\._\3-\2-\1_;s_\([0-9]\{4\}\)-\([0-9]\{2\}\)-00_\1-\2-01_;s_\([0-9]\{4\}\)-00-\([0-9]\{2\}\)_\1-01-\2_' data.csv
php cleandata.php data.csv > data_clean.php
