Created attachment 37209 [details] Highlighted XML with a template variable shown as a literal When we have XML in a request body, it's displayed using syntax highlighting that doesn't differentiate between literal content and template variables (as the image shows). Ideally, the template variable should be highlighted in a different color to make it easier to see it.
Looks like a fix would need to happen in RSyntaxTextArea. I'll open a ticket on their issue tracker and this could become adding a version with the fix to the configuration for JMeter.
The issue at the RSyntaxTextArea tracker is https://github.com/bobbylight/RSyntaxTextArea/issues/344
