PowerShell Array Operations

 

Split string into data

Cls # original string $ str = "abc, def, ghi, mon" # data definition # $ StrArray = New-Object Collections. generic. list [string] $ StrArray = @ () # split $ StrArray = $ str. split (",") $ len = $ StrArray. countWrite-Host "Total number of elements in the data:" $ len # traverse the data element foreach ($ str in $ StrArray) {$ str}

The execution result is:

　　

　　

An array can be defined in two ways: New-Object Collections. Generic. List [string] And @()

$ StrArray = New-Object Collections. Generic. List [string]
$ StrArray = @()

Even if it is defined as an int type data group: $ StrArray = New-Object Collections. Generic. List [int], if it is assigned a value as a string, no error is returned?

The execution result is as follows:

 

Read the information in the text file in an array.

Cls $ content = Get-Content "d: 1.txt" $ contentTmp =" "foreach ($ line in $ content) {$ contentTmp = $ contentTmp + $ line} $ StrArray = New-Object Collections. generic. list [string] # split $ StrArray = $ contentTmp. toString (). split (",") $ len = $ StrArray. countWrite-Host "Total number of elements in the data:" $ len # traverse the data element foreach ($ str in $ StrArray) {$ str}

 

The original text file looks so long

Convert to the data read result

 

PowerShell XML data operations

Read XML data and node Information

Cls # function GetAlterCounter ($ path) {$ XML = [xml] (Get-Content $ path) $ list = $ xml. messageData. note $ list} $ xmlList = New-Object Collections. generic. list [string] $ xmlList = GetAlterCounter ("C: \ WORKSPACE \ PowerShellScript \ TestReadXml. xml ") foreach ($ obj in $ xmlList) {Write-Host "**********************" Write-Host $ obj. id Write-Host $ obj. to Write-Host "*********************"}

The original XML file looks like this

Here, we read the information of the IDS and the two nodes. The result is as follows:
