When I open an archive in Ark, then click on an XML file to view it, a window opens displaying sometimes nothing and sometimes values from within some of the tags (concatenated together in a meaningless sequence, since the context of their tags is not visible). What I want to do is view the text (optionally with syntax highlighting).

XML is a container format for "configuration" files. Only a small sub-set, such as XHTML files and some XML files with embedded XSLT components, can actually be rendered meaningfully in a web-browser.

Note: I have a feeling I've reported this before, but cannot find anything in the bug-tracker.

Reproducible: Always

Steps to Reproduce:
If you want an example, try opening one of the [OpenMalaria release archives](https://github.com/SwissTPH/openmalaria/releases) in Ark. Most contain at least one XML file, which if opened in Ark is displayed in a completely meaningless way. Extracted then opened with KWrite or another text editor the full document is visible.

(Note that the standard file associations seem to do the same thing and open in a web browser by default — but this is easy to fix or work-around via right-click, "open with ...". Ark is not, hence this report.)
