powershell - How to see if the next line of a TXT file starts with a number -


I am using powershell to read in a TXT and make some arguments for it. The TXT is setup in a very specific format, but I only care about one line that starts with 6 or 4. The problem is that I do not know how to check the next line. I 

  $ files = Get-ChildItem $ source *. Starting with $ $ File = Get-content $ files   
 and then check for each line  
  foreach ($ $ in file Line "StartsWith" ("6") {Write-Host "It starts with line 6"} elseif ($ line.StartsWith ("4")) {Write-host "This line 4 ") otherwise {($ line.StartsWith (" 4 ")) and (start with the next line 4)) {Write - Host" This line begins with 4 and starts with the next line 4 "}" And {write-host "does not start with line 6 or 4 I  $ line + 1  or  $ line [x + 1]  and even    
 $ file [x + 1]  but did not generate results from what I want because they will read in line and next next line can someone tell me how to check if the next $ line 4 starts   
 
 
 complete this what you need, the way I parse the text files Going  $ file = Get-content $ files  It seems ... by using the  for loop  we create a reference point  $ i  to look forward to the array in  $ content  Can be used  
  and  the second part of the statement -  (($ i + 1) -lt $ content.Count  - ensures that You do not get OOB exception if you want to appear beyond the "edge" of the  $ content  array, i.e. looking at the last line ($ i = $ content.Count-1)  
  $ files = Get-ChildItem $ source *. * Foreach ($ file in $ files) {$ content = Get-content $ for file ($ i = 0; $ i -lt $ content.Count; $ i ++) {$ Line = $ content [$ i] If the line ("$ 6") with line $. ("6") {Write-host "This line starts with 6"} elseif ($ line.StartsWith ("4")) {write-host "This line 4 ("$ line. StartsWith" ("4") and (($ i + 1) -lt $ content.Count) {$ nextLine = $ content [$ i + 1] if ( $ Next line. Start ("4") {Write-host "It starts with line 4 and starts with next line 4"}} and {write-host "starts with row 6 or 4The o occurs} "}}   
 Hope this helps.
