The XSLT Apply Template tag is used to apply the appropriate templates in the context of the selected node. This tag is used to direct the processor to apply templates on node elements of XML.
Syntax:
<xsl:apply-template
select = Expression
mode = Name>
// Other content
</xsl:apply-template>
Attributes:
- select: It is an XPath expression to find the node to select.
- mode: If there are multiple processing ways for a node this parameter is used to distinguish between them.
Example 1: In this example, we will apply templates for different nodes of XML which show values of nodes in different colors. Save the given file as specified and view the xsl file in the web browser.

In conclusion, The <xsl:apply-templates> tag is a fundamental building block in XSLT transformations, allowing you to define how XML data is processed and transformed into various formats. By selecting nodes and applying specific templates, you can achieve precise control over the transformation process, making XSLT a powerful tool for data conversion and presentation.
