How can I suppress globbing in parameter expansion?

Is there a way to suppress globbing in parameter expansion? Consider the case of a file named literally *.xml in a directory among other xml files. Is there a way to do a parameter expansion ${param##*/} affecting only the file *.xml and not all the xml files?

param=./*.xml
echo "$param" # Displays only ./*.xml
echo $param # Displays ./*.xml ./invoice.xml ./bla.xml ...
echo ${param##*/} # Displays *.xml invoice.xml bla.xml ...
# what I want:
echo ${param##*/} # Displays only *.xml

Converting my comment to answer so that solution is easy to find for future visitors.

Problem is not quoting your BASH expressions that allows shell to expand globs or wildcards.

You should be using quotes in shell as:

param='./*.xml'
echo "$param"
echo "${param##*/}"
