XSLT match Attribute 🎯

Welcome to CodeYourCraft's comprehensive guide on XSLT (Extensible Stylesheet Language Transformations)! Today, we're going to learn about matching attributes using XSLT.

What is XSLT Match Attribute? 📝

In XSLT, match is used to select XML elements and attributes based on specific criteria. Today, we'll focus on matching attributes.

Why Match Attributes? 💡

Matching attributes helps us access and manipulate specific data attributes from the XML document, making it easier to transform and present the data in a desired format.

Basic XSLT Syntax 📝

Here's a brief recap of the basic XSLT syntax we'll be using today:

xml

<xsl:template match="element-name">
  <!-- XSLT code here -->
</xsl:template>

In the above syntax, replace element-name with the name of the XML element you want to select.

Matching Attributes 🎯

Now, let's dive into matching attributes. To match an attribute, we use the @ symbol followed by the attribute name.

xml

<xsl:template match="element-name[@attribute-name]">
  <!-- XSLT code here -->
</xsl:template>

Example 1: Simple Attribute Match

Let's take an XML example to understand this better:

xml

<book id="123">
  <title>Learning XSLT</title>
  <author>John Doe</author>
</book>

Now, let's create an XSLT template to match the id attribute of the book element:

xml

<xsl:template match="book[@id]">
  <h1>Book ID: <xsl:value-of select="@id"/></h1>
</xsl:template>

When you transform the XML using this XSLT, it will output:

html

<h1>Book ID: 123</h1>

Example 2: Complex Attribute Match

Let's consider a more complex XML example:

xml

<product id="123" price="50.99" color="red">
  <name>XSLT Book</name>
</product>

Now, let's create an XSLT template to match the color attribute of any element:

xml

<xsl:template match="*[@color]">
  <h1>Color: <xsl:value-of select="@color"/></h1>
</xsl:template>

When you transform the XML using this XSLT, it will output:

html

<h1>Color: red</h1>
