Alright, perfect. It works.

However, many variables that I create are based on the POSSIBILITY that 
a certain xpath/string exists in a file. If it doesnt, it should 
preferably return a nil or a 'no'.

By using at_xpath and then .content, if an xpath (for example pvda = 
searchablefile.at_xpath("//h1[contains(text(), 'pvda')]") returns 
nothing, the variable.content (in this case sheet1[row,1] = 
pvda.content) does not work, and it no longer runs the rest of the code 
(error = undefined method 'content' for nil:nilClass (NoMethodError)

How can I work around this and/or save boolean on the basis of xpath?
