I referenced  benjamin-hubbard  s answer above to parse the output of dnscmd for A records  and generate a PHP  dictionary  key-value pairs of IPs and Hostnames  I strung multiple -replace args together to replace text with nothing or tab to format the data for the PHP file    DnsDataClean    DnsData       -match    a-zA-Z0-9    sA s          -replace  172  30       P         -replace                 -replace   s 0-9   sA s    t    DnsDataTable      DnsDataClean         ForEach-Object             HostName       -split   t   0              IpAddress       -split   t   1               t   IpAddress   t  gt  t  HostName    n            sort       t    P 255 255   t  gt  t None      lt  php   P    10 213     IpHostArr     n n DnsDataTable n      gt     Out-File -Encoding ASCII -FilePath IpHostLookups php  Get-Content IpHostLookups php

Another way to do this is with operator -replace    TestString    test keep this  but not this     NewString    TestString -replace       -replace             means any number of characters up to and including an equals sign       means a comma followed by any number of characters   Since you are basically deleting those two parts of the string  you don t have to specify an empty string with which to replace them  You can use multiple -replaces  but just remember that the order is left-to-right

This is really old  but I wanted to add my slight variation for anyone else who may stumble across this  Regular expressions are powerful things   To keep the text which falls between the equal sign and the comma   -replace                     1    This regular expression starts at the beginning of the line  wipes all characters until the first equal sign  captures every character until the next comma  then wipes every character until the end of the line  It then replaces the entire line with the capture group  anything within the parentheses   It will match any line that contains at least one equal sign followed by at least one comma  It is similar to the suggestion by Trix  but unlike that suggestion  this will not match lines which only contain either an equal sign or a comma  it must have both in order
