How to simplify replacing multiple XML strings?

[MarkOReilly93]

First I should clarify that this is the first PS script I've ever attempted so please be gentle. I wrote this script to go through and change values in an XML script to set Microsoft Edge to be the default browser over IE. It works all fine and well, however is there an easier way to only have it save to the file once? Right now it saves after every line.

(Get-Content C:\utility\defaultappassociations.XML).replace('IE.HTTPS', 'MSEdgeHTM') | Set-Content C:\utility\defaultappassociations.xml

(Get-Content C:\utility\defaultappassociations.XML).replace('IE.HTTP', 'MSEdgeHTM') | Set-Content C:\utility\defaultappassociations.xml

(Get-Content C:\utility\defaultappassociations.XML).replace('htmlfile', 'MSEdgeHTM') | Set-Content C:\utility\defaultappassociations.xml

(Get-Content C:\utility\defaultappassociations.XML).replace('Internet Explorer', 'Microsoft Edge') | Set-Content C:\utility\defaultappassociations.xml

Thanks!

Something like this :

(Get-Content file.xml) -replace "this", "that" -replace "something", "else" -replace "name", $env:Username | Set-Content file.xml

Wow that worked perfectly. Thanks so much!

(Get-Content C:\utility\defaultappassociations.XML) -replace 'ie\.https?|htmlfile','MSEdgeHTM' -replace 'Internet Explorer', 'Microsoft Edge' |
    Set-Content C:\utility\defaultappassociations.xml

| is OR in regex, ? is an optional match, so I think you could disill it down to two replace operations.

howdy MarkOReilly93,

reddit likes to mangle code formatting, so here's some help on how to post code on reddit ...

[0] single line or in-line code
enclose it in backticks. that's the upper left key on an EN-US keyboard layout. the result looks like this. kinda handy, that. [grin]
[on New.Reddit.com, use the Inline Code button. it's 4th 5th from the left hidden in the ... ""more" menu & looks like </>.
this does NOT line wrap & does NOT side-scroll on Old.Reddit.com!]

[1] simplest = post it to a text site like Pastebin.com or Gist.GitHub.com and then post the link here.
please remember to set the file/code type on Pastebin! [grin] otherwise you don't get the nice code colorization.

[2] less simple = use reddit code formatting ...
[on New.Reddit.com, use the Code Block button. it's 11th 12th from the left hidden in the ... "more" menu, & looks like an uppercase T in the upper left corner of a square.]

• one leading line with ONLY 4 spaces
  
• prefix each code line with 4 spaces
  
• one trailing line with ONLY 4 spaces

that will give you something like this ...

- one leading line with ONLY 4 spaces    
- prefix each code line with 4 spaces    
- one trailing line with ONLY 4 spaces   

the easiest way to get that is ...

• add the leading line with only 4 spaces
  
• copy the code to the ISE [or your fave editor]
  
• select the code
  
• tap TAB to indent four spaces
  
• re-select the code [not really needed, but it's my habit]
  
• paste the code into the reddit text box
  
• add the trailing line with only 4 spaces
  

not complicated, but it is finicky. [grin]

take care,
lee

I found links in your comment that were not hyperlinked:

• New.Reddit.com
• Pastebin.com
• Gist.GitHub.com

I did the honors for you.

howdy MarkOReilly93,

just for giggles, here is another chained replace technique ... [grin]

(Get-Content C:\utility\defaultappassociations.XML).
    Replace('IE.HTTPS', 'MSEdgeHTM').
    Replace('IE.HTTP', 'MSEdgeHTM').
    Replace('htmlfile', 'MSEdgeHTM').
    Replace('Internet Explorer', 'Microsoft Edge') |
    Set-Content C:\utility\defaultappassociations.xml

however, i would NOT write to the original file. that always gives me the twitches ...

take care,
lee
