Dynamic Variable Replacer (Multi Variable)

Allows dynamic updating of a flow variable based on other existing flow variables.
Replaces any tags in the specified value, using the format defined in the Text View documentation, with the flow variable named in the tag.

e.g. $$["myvar"]
would be replaced with the contents of variable myvar.

This compnent is based on my HTML Flow Variable Replacer, and uses the Dynamic Variable Creator component to perform the replacements, but it differs in that provides for multiple variables to be replaced on pre-existing variables.

Options

Include Type Identifier in dynamic variables

Select this if the variable names include a "type identification" letter (e.g. S for String) before the name

Choose variables to be evaluated/replaced

Specify the list of String flow-variables that are to be evaulated and replaced. Any variable "tags" found within the contents of each flow-variable will be replaced with the value of the specified variable. Tags take the form $$["variable-name"] using the same notation found in the Table Text node

Dynamic Variable format

Choose the string format for inclusion of dynamic variables. KNIME has a variety inconsistent formats across the various nodes used by the different nodes. The aim here is to provide most of the familiar formats.%%00010You can also include the following auto-supplied date/time variables:%%00010Date: dt#yyyy (year) dt#mm (month) dt#dd (day) dt#month (month name) dt#ymd (year-month-day)%%00010Time: tm#hh (hour) tm#mm (minute) tm#ss (second) dt#dts (datetimestamp yyyyMMddhhmmss)
