XSLT Format-Number Tutorial 🎯

Welcome to our comprehensive guide on XSLT Format-Number! In this tutorial, we'll delve into the exciting world of XSLT and learn how to format numbers using this powerful tool. By the end of this lesson, you'll be able to create real-world XML documents that look clean and professional.

Understanding XSLT 📝

XSL Transformations (XSLT) is a language used for transforming XML documents into other formats such as HTML, PDF, and more. It's like a bridge between XML and other languages.

Format-Number in XSLT 💡

The format-number() function in XSLT allows us to format numbers according to a given pattern. This function takes two arguments: the number to be formatted and the format-string.

Basic Format-Number Example ✅

Let's start with a simple example:

xml

<xsl:template match="/">
  <html>
    <body>
      <h1>Formatted Number</h1>
      <p><xsl:value-of select="format-number(12345.678, '0,')"/></p>
    </body>
  </html>
</xsl:template>

In this example, we're transforming an XML document into HTML. The format-number(12345.678, '0,') function is used to format the number 12345.678 with a comma as the thousand separator.

Format-Number Syntax 📝

The format-string is composed of the following components:

#: Represents a digit in the number.
,: Separates thousands.
.: Separates decimal places.
#.##: Specifies the number of decimal places.
e: Allows scientific notation.

Advanced Format-Number Example ✅

Here's a more complex example:

xml

<xsl:template match="/">
  <html>
    <body>
      <h1>Formatted Number</h1>
      <p><xsl:value-of select="format-number(123456789.123456, '0,,.,"e")"/></p>
    </body>
  </html>
</xsl:template>

In this example, we're formatting the number 1,234,567,891.123456 with a comma as the thousand separator, a period as the decimal separator, and scientific notation for numbers larger than a million.
