I was under impression that

rm -r *.xml

would remove all file from parent and child however:

*.xml: No such file or directory

    Reading this answer on finding empty directories unix, I just learned about the -delete action:

    -delete
              Delete  files; true if removal succeeded.  If the removal failed, an error message is issued.  If -delete fails, find's exit status will be nonzero (when it even‐
              tually exits).  Use of -delete automatically turns on the -depth option.
    
              Warnings: Don't forget that the find command line is evaluated as an expression, so putting -delete first will make find try to delete everything below the start‐
              ing  points  you  specified.   When  testing a find command line that you later intend to use with -delete, you should explicitly specify -depth in order to avoid
              later surprises.  Because -delete implies -depth, you cannot usefully use -prune and -delete together.
    

    Source: man find

    That means, you can also delete all xml-files recursively like this:

    find . -name "*.xml" -type f -delete

    An easy way to do is

    rm -f *.xml

    This will remove all .xml files from current directory.

    I'm assuming you want to remove all *.xml files recursively (within current and all sub directories). To do that, use find:

    find . -name "*.xml" -exec rm {} \;
    

    On a side note, recursive deletion scares me. On my saner days, I tend to precede that step with:

    find . -name "*.xml" 
    

    (without the -exec bit) just to see what might get deleted before taking the leap. I advice you do the same. Your files will thank you.

    more beautiful way, although this one is less supported in unix systems:

    rm -rf */*.xml
    

    this will remove xml files from all sub-directories of you current directory.

    ZSH recursive globbing to the rescue!

    Invoke zsh: zsh

    Be sure you're in the dir you intend to be in: cd wherever

    List first: ls **/*.xml

    Remove: rm **/*.xml

    I'll resist the strong temptation to bash on bash, and just point to the relevant zsh docs on the topic here.

    The man page of rm says:

     -r, -R, --recursive
              remove directories and their contents recursively
    

    This means the flag -r is expecting a directory. But *.xml is not a directory.

    If you want to remove the all .xml files from current directory recursively below is the command:

    find . -name "*.xml" -type f|xargs rm -f
