How to open xml format file? ( as document)

https://dumps.wikimedia.org/enwiki/latest/

I tried to open 'enwiki-latest-abstract22.xml.gz-rss.xml' file, but MATLAB Editor says 'There is not enough memory to open enwiki-latest-abstract22.xml in the Editor.

And Error message at command window as

Please recheck which file you were working with. You talk about opening xml.gz-rss.xml but the error message is about .xml withotu .gz-rss.xml .

enwiki-latest-abstract22.xml is not directly available at that link, but enwiki-latest-abstract22.xml.gz is there; it is about 16 megabytes, and expands into 130 megabytes.

I was able to open the complete file in the MATLAB editor on my OS-X system. Go into Preferences -> General -> Java Heap Size and configure a larger heap size. I happened to have 2048 Mb configured on my system.

You might have to restart MATLAB after you configure the Java Heap Size.

I tried to open both files. Really thanks for your answer!
