win7自带的正则表达式验证工具----powershell

　　最近项目中要用正则表达式,忽然想起powershell可以啊...
　　用了一下,很爽...
　　下面给个例子
　　$str = 'eax=77431182 ebx=7ffd8000 ecx=00000000 edx=00123689 esi=00000000 edi=00000000'
　　$str1 = 'eip=00123689 esp=0023f7e4 ebp=0023f7ec iopl=0         nv up ei pl zr na pe nc'
　　$str -match 'eax=([0-9a-f]{8}) ebx=([0-9a-f]{8}) ecx=([0-9a-f]{8}) edx=([0-9a-f]{8}) esi=([0-9a-f]{8}) edi=([0-9a-f]{8})'
　　$matches
　　输出
　　6                              00000000                                                                       
　　5                              00000000                                                                       
　　4                              00123689                                                                       
　　3                              00000000                                                                       
　　2                              7ffd8000                                                                       
　　1                              77431182                                                                       
　　0                              eax=77431182 ebx=7ffd8000 ecx=00000000 edx=00123689 esi=00000000 edi=00000000
　　-match是正则验证,类似regex_search
　　验证完,将结果放在全局变量$matches中
