powershell Find and replace text in a config file-CodePudding

I have a config file with text within which i would like to replace.

The text in the config file looks like the following

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <applicationSettings>
      <setting name="ExtendTimeMins" serializeAs="String">
        <value>5</value>
      </setting>
      <setting name="DisableHotkeySupport" serializeAs="String">
        <value>False</value>
      </setting>
      <setting name="ServerPingInterval" serializeAs="String">
        <value>00:00:10</value>
      </setting>
      <setting name="DirectorySweepRate" serializeAs="String">
        <value>00:10:00</value>
      </setting>
      <setting name="StopSignalExitDelaySecs" serializeAs="String">
        <value>0</value>
      </setting>
  </applicationSettings>
</configuration>

I want to change the False value of DisableHotkeySupport to True, but not change the StopSignalExitDelaySecs value.

Does anyone have any advice how to do this.

Thanks for showing the entire config XML

To change the <Value>False</Value> into <Value>True</Value> for just the setting with name="DisableHotkeySupport" do not try to use text replacements, but instead:

$file = 'X:\TheConfigFile.config'  # full path to your config file goes here
# load the file in a new XmlDocument object
$xml = [System.XML.XMLDocument]::new()
$xml.Load($file)
($xml.configuration.applicationSettings.setting | Where-Object { $_.name -eq 'DisableHotkeySupport' }).Value = 'True'
# save the updated file
$xml.Save($file)

The same answer although using a somewhat different syntax...

[xml]($config = @'
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <applicationSettings>
      <setting name="ExtendTimeMins" serializeAs="String">
        <value>5</value>
      </setting>
      <setting name="DisableHotkeySupport" serializeAs="String">
        <value>False</value>
      </setting>
      <setting name="ServerPingInterval" serializeAs="String">
        <value>00:00:10</value>
      </setting>
      <setting name="DirectorySweepRate" serializeAs="String">
        <value>00:10:00</value>
      </setting>
      <setting name="StopSignalExitDelaySecs" serializeAs="String">
        <value>0</value>
      </setting>
  </applicationSettings>
</configuration>
'@)

$setting = $config.configuration.applicationSettings.setting | 
where name -eq 'DisableHotkeySupport'

$setting.Value = 'True'

$config.Save('mydata.xml')
