To check: when a tag contains "<" or ">"

[smart-fun]

Received from LinkedIn:

[...] when one of the tag's content contains "<", ">" symbols, it will cut the text off. Like <Abstract> mast cell (p < 0.001) infiltration</Abstract>. The output will be {"Abstract" : "infiltration" }

The "<" character is not valid in a xml file and must be escaped.
