OIC - XSLT - "Using format-number() to Add Leading Zeros to Single-Digit Numbers"

Use Case:

In data processing or reporting scenarios, leading zeros are crucial for ensuring consistency and accuracy in how numbers are displayed, especially for dates. 

For example, when formatting dates such as "Day 1" or "Day 9," it’s essential to present them as "01" and "09" to maintain uniformity, especially when aligning values in tables or spreadsheets. 

Using the format-number function, such as fn: format-number(ns28: Input Day, "00"), ensures that single-digit day values are always presented with a leading zero, improving both readability and data integrity in systems requiring consistent date formatting.

Code:

fn: format-number (ns28: Input Day, "00")
