USE:
int4 IFTT uses XPath expressions to extract specific values from xml files. For fetching values from flat file messages int4 IFTT uses our simple language created specifically for this purpose.
...
- CSV_COLUMN - in CSV file column number for further extraction
- CSV_SEPARATOR - optional separation character different than comma
- CSV_SKIP_HEADER - skips first row in the CSV file
- START_TAG - determine string, as the starting point
- START_FROM - determine from which character after string defined in START_TAG derivation should start. First character is 1
- LENGTH - determine length of string, that will be saved
- END_TAG - determine string, as the ending point
- REGEX - match specific part of the file using regular expression.
By default whole regular expression is matched and used for variable replacement. It is possible to use subgroups to extract/replace part of the expression. If there is a subgroup defined it is used instead of the whole result. See example 5 below.

In this case the expression will work independently of the values length just starting from a specify point till the end tag.
