ruby的正则表达式-scan方法

irb(main):001:0> str_vps=%Q{viewpoint_ids: [{"id":"260e053b-d728-4785-888d-eb4f1ca0a194","name":"全 局管综视点"},{"id":"7a1baa69-baab-434f-bcf0-aa885ab07ed4","name":"管综细部"},{"id":"441d05a2-bcc6-4e19-8eb7-f239934f395c","name":"空调机组"}]}
=> "viewpoint_ids: [{"id":"260e053b-d728-4785-888d-eb4f1ca0a194","name":"全局管综视点"},{"id":"7a1baa69-baab-434f-bcf0-aa885ab07ed4","name":"管综细部"},{"id":"441d05a2-bcc6-4e19-8eb7-f239934f395c","name":"空调机组"}]"

irb(main):018:0> str_vps.scan(/id":"([^"]*?)","name":"([^"]*?)"}/) do |matched|
irb(main):019:1* p matched
irb(main):020:1> end
["260e053b-d728-4785-888d-eb4f1ca0a194", "全局管综视点"]
["7a1baa69-baab-434f-bcf0-aa885ab07ed4", "管综细部"]
["441d05a2-bcc6-4e19-8eb7-f239934f395c", "空调机组"]
=> "viewpoint_ids: [{"id":"260e053b-d728-4785-888d-eb4f1ca0a194","name":"全局管综视点"},{"id":"7a1baa69-baab-434f-bcf0-aa885ab07ed4","name":"管综细部"},{"id":"441d05a2-bcc6-4e19-8eb7-f239934f395c","name":"空调机组"}]"

利用scan方法，将将视点的id,name属性匹配出来。
