How to Remove Quantity Tags from NetSuite Advanced PDF Inventory Detail

Yes, FreeMarker supports using regular expressions within its replace function. The standard use of the replace function, which only works with exact string matches, is demonstrated below:

${tranline.inventorydetail?replace("car", "bulldozer")}

This would result in: "this is a bulldozer abulldozerus"

By adding the 'r' flag as an optional third parameter, the FreeMarker compiler is instructed to treat the search string as a regular expression. For removing parentheses and the characters between them, an initial regex attempt might be:

${tranline.inventorydetail?replace("(.*)"," ","r")}

However, this standard regex code crashes the FreeMarker compiler due to how it interprets backslashes. The backslash character needs to be doubled:

${tranline.inventorydetail?replace("\(.*\)"," ","r")}

A further consideration is that the .* sequence, by default, should not pick up newline characters, but in FreeMarker, it does. To specifically target digits within the parentheses and avoid unintended matches across lines, .* should be replaced with \d*. The final, working solution is as follows:

${tranline.inventorydetail?replace("\(\d*\)"," ","r")}
