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
Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space

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.
