「安卓按键精灵」几种字符串提取的方法（源码）

       截取法提取两个字符串之间的内容

       TracePrint GetStrAB("如果想要写成一行代码，那么就可以用冒号连接","想要","代码")

       Function GetStrAB(str,StrA,StrB)

       If UTF8.InStr(1, str, StrA)>0 and utf8.instr(1,str,StrB) > 0 Then

       Dim m=utf8.instr(1,Str,StrA)

       Dim n=utf8.instr(m,Str,StrB)

       GetStrAB=utf8.mid(str,m+utf8.len(StrA),n-m-utf8.len(StrA))

       End If

       End Function

       分割法提取字符串

       TracePrint SplitStrAB("如果想要写成一行代码，那么就可以用冒号连接",unity 祖玛源码"想要","代码")

       Function SplitStrAB(str, StrA, StrB)

       If UTF8.InStr(1, str, StrA) > 0 and UTF8.InStr(1, str, StrB) > 0 Then

       Dim arr_A=split(str,StrA)

       Dim arr_B=split(arr_A(1),StrB)

       SplitStrAB=arr_B(0)

       end if

       End Function

       取多组两个字符串之间的内容

       Dim arr=GetStrArr("如果(公众号3分钟学堂)写成一行(代码)，那么就(可以)用冒号连接","(",")")

       For Each k In arr

       TracePrint k

       Next

       Function GetStrArr(str, StrA, StrB)

       If UTF8.InStr(1, str, StrA) > 0 and UTF8.InStr(1, str, StrB) > 0 Then

       Dim str_arr=array()

       Dim n=0

       Dim arr_A=split(str,StrA)

       Dim arr_B

       For i = 1 To UBOUND(arr_A)

       If InStr(1,arr_A(i),StrB) > 0 Then

       arr_B = Split(arr_A(i), StrB)

       str_arr(n) = arr_B(0)

       n=n+1

       End If

       Next

       GetStrArr=str_arr

       end if

       End Function

       提取数字

       TracePrint GetNum("如果_ba@d1b都是a2aaf%b连接")

       Function GetNum(str)

       Dim Num

       For i = 1 To UTF8.Len(str)

       If IsNumeric(utf8.StrGetAt(str,i)) Then

       Num=Num&utf8.StrGetAt(str,i)

       End If

       Next

       GetNum=Num

       End Function

       提取字母

       TracePrint GetZm("如果_ba@d1b都是a2aaf%b连接")

       Function GetZm(str)

       Dim zm

       For i = 1 To UTF8.Len(str)

       If < CInt(Asc(utf8.StrGetAt(str, i))) < or < CInt(Asc(utf8.StrGetAt(str, i))) < Then

       zm=zm&utf8.StrGetAt(str,i)

       End If

       Next

       GetZm=zm

       End Function

       提取汉字

       TracePrint GetCN("如果_ba@d1b都是a2aaf%b连接")

       Function GetCN(str)

       Dim CN

       For i = 1 To UTF8.Len(str)

       If Len(utf8.StrGetAt(str, i)) = 3 Then

       CN=CN&utf8.StrGetAt(str, i)

       End If

       Next

       GetCN=CN

       End Function

       正则提取数字

       import"shanhai.lua"

       Dim str="如果_ba@d1b都是a2aaf%b连接"

       dim arr= shanhai.RegexFind(str,"%d+")

       TracePrint join(arr,"")

       正则提取字母

       import"shanhai.lua"

       Dim str="如果_ba@d1D都是a2aaf%b连接"

       dim arr= shanhai.RegexFind(str,"%a+")

       TracePrint join(arr,"")

       正则提取汉字

       import"shanhai.lua"

       Dim str="如果_ba@d1D都是a2aaf%b连接"

       dim arr= shanhai.RegexFind(str,"[\-\]+")

       TracePrint join(arr,"")

用vb获取任一网页源代码,要完整的!!!,可以用webbrowser控件

vb问题：希望可以给代码
