  7. google.com/search?q=beyonce

  8. google.com/search?q=beyonce

  9. google.com/search?q=beyonce command delimiter parameter value

  10. google.com/search?q=beyonce google.com/search?q=beyonce&num=1 all delimiters after the first “?” are “&”s

  11. google.com/search?q=beyonce google.com/search?q=beyonce&num=1 google.com/search?q=beyonce&num=5&hl=es

  12. google.com/search?q=beyonce google.com/search?q=beyonce&num=1 google.com/search?q=beyonce&num=5&hl=es twitter.com/?lang=es youtube.com/watch?v=iScNjy7U-Zo

  13. Step 2: Write some URLs

  14. USA.gov Social Media Registry Agencies API + Services API + Accounts API

  15. registry.usa.gov/agencies

  16. registry.usa.gov/agencies registry.usa.gov/agencies.xml

  17. registry.usa.gov/agencies registry.usa.gov/agencies.xml registry.usa.gov/agencies.json

  18. registry.usa.gov/services registry.usa.gov/services.xml registry.usa.gov/services.json

  19. registry.usa.gov/accounts registry.usa.gov/accounts.xml registry.usa.gov/accounts.json

  20. registry.usa.gov/accounts?service_id=twitter&agency_id=nasa

  21. registry.usa.gov/accounts?service_id=twitter&agency_id=nasa registry.usa.gov/accounts.xml?service_id=twitter&agency_id=nasa registry.usa.gov/accounts.json?service_id=twitter&agency_id=nasa

  22. Step 3: Tell some machines to read our data

  23. Google Spreadsheets + importXML()

  24. =importXML( "http://registry.usa.gov/agencies.xml", "//agency_name" )

  25. =importXML( "http://registry.usa.gov/agencies.xml", "//agency_name" ) data source XPath

  26. =importXML( "http://registry.usa.gov/agencies.xml", "//agency_name" ) =importXML( "http://registry.usa.gov/agencies.xml", "//agency_id" ) =importXML( "http://registry.usa.gov/services.xml", "//service_id" )

  27. =importXML( "http://registry.usa.gov/accounts.xml?service_id=twitter&agency_id=nasa", "//service_url" )
