| > rm -rf extracted | |
| # Remove any untouched incomplete tags | |
| sed -i.bak -e 's/<[^doc>/!][^ >][^>]*>//g;s/<\/[^doc>][^>]*>//g' wiki_parsed.xml | |
| # Prepend a head tag to validate a proper xml to be parsed by xml parsers | |
| echo "<head>"|cat - yourfile > /tmp/out && mv /tmp/out yourfile | |
| OR | |
| sed -i '1s/^/<head> /' file | |
| check if the last doc tag is closed or not if not close it. | |
| #Close the head tag | |
| echo "</head>" >> file | |
| # Incase we want to go with the split the big xml into the smaller files one for each article. | |
