    ${b}                Parse Xml  <units>mm[Hg]</units>
    
                        Elements Should Match  ${a}  ${b}


XML Elements Should Be Equal
    ${a}                Parse Xml  <units>mm[Hg]</units>
    ${b}                Parse Xml  <units>mm[Hg]</units>
    
                        Elements Should Be Equal  ${a}  ${b}

Pattern matching

Some keywords, for example Elements Should Match, support so called
[http://en.wikipedia.org/wiki/Glob_(programming)| glob patterns where:

PATTERN	MATCH
*	matches any string, even an empty string
?	matches any single character
[chars]	matches one character in the bracket ⚠️ ⚠️ ⚠️
[!chars]	matches one character not in the bracket
[a-z]	matches one character from the range in the bracket
[!a-z]	matches one character not from the range in the bracket

Unlike with glob patterns normally, path separator characters / and
\ and the newline character \n are matches by the above wildcards.

Support for brackets like [abc] and [!a-z] is new in Robot Framework 3.1
