Validate sitemap.xml
Shell command to validate sitemap.xml
# cat sitemap.xml | grep '<loc>http' | sed 's/<loc>//g' | sed 's/<\/loc>//g' | while read PAGE; do STATUSCODE=$(curl --silent --output /dev/null --write-out "%{http_code}" $PAGE); if test $STATUSCODE -ne 200; then echo "HTTP STATUS CODE $STATUSCODE -> $PAGE"; else echo "OK -> $PAGE"; fi done
