For large XML files it seems like the Visual Studio text editor will not attempt to do syntax highlighting, so everything is black and white.
Is there a way to force it to parse for highlighting?

It turns out the maximum file size for the XML editor is 10 MB. After changing the limit in the following key, syntax highlighting is back with no noticeable performance issues:
HKCU\Software\Microsoft\VisualStudio\11.0_Config\XmlEditor\MaxFileSizeSupportedByLanguageService
Run regedit to navigate to that path in the Windows Registry. HKCU stands for HKEY_CURRENT_USER.

Run this in powershell for VS 2017 and higher
$vsWherePath = Join-Path ${env:ProgramFiles(x86)} "Microsoft Visual Studio\Installer\vswhere.exe"
$installPath = &$vsWherePath -all -latest -property installationPath
$vsregedit = Join-Path $installPath 'Common7\IDE\vsregedit.exe'
& $VsRegEdit read "$installPath" "HKLM" "XmlEditor" "MaxFileSizeSupportedByLanguageService" string
& $VsRegEdit set "$installPath" "HKLM" "XmlEditor" "MaxFileSizeSupportedByLanguageService" string 100
& $VsRegEdit read "$installPath" "HKLM" "XmlEditor" "MaxFileSizeSupportedByLanguageService" string

Just how large are we talking about here? – Karan – 2012-11-23T21:32:32.490
@Karan I'm sorry, it's 14MB. – Louis – 2012-12-16T02:37:49.503
1Actually, I just noticed the Output window shows a warning:
'file.xml' is too large to open with XML editor. The maximum file size is '10' MB. Please update the registry key 'HKCU\Software\Microsoft\VisualStudio\11.0_Config\XmlEditor\MaxFileSizeSupportedByLanguageService' to change the maximum size.Changed that fixed it =! – Louis – 2012-12-16T02:41:14.837
