如何从一个一定记录格式的字符串中读出格式?

比如:(14235.55,88768,44)--(6547.33,656.21)--(46547.44,47778.33)--|(432543.66,6547.32)--(8657.22,76587.22)--(53467.33,758.76)--(23476.11,4367.557)--(5436.33,6577.12)--|(5437.67,6547.233)--等等
或者[14235.55,88768,44]&***[6547.33,656.21]&***[46547.44,47778.33]&***^[432543.66,6547.32]&***(8657.22,76587.22)&***[53467.33,758.76]&***[23476.11,4367.557]&***[5436.33,6577.12]&***^[5437.67,6547.233]&***等等我遇到的直接难点就是从这么组织的字符串中读出数值部分?谢谢
