The extraction command was described in the previous section. For example, according to this command, the content of exData may be enclosed in an Xml node whose label is specified in the extraction command. or / Also / Moreover / As another example / in another command / In addition, a regular expression may be applied to exData in order to extract and store only specific parts of it.
I want to mention another case where the extraction command is employed. Maybe "or" is the simplest choice but it makes the sentence too long. Then, I don't know which alternative word to use here.
