An XSL style sheet consists of one or more set of rules that are called templates.
A template contains rules to apply when a specified node is matched.
<xsl:template> Element
<xsl:template> element is used to build templates. It defines a way to reuse templates in order to generate the desired output for nodes of a particular type/context.
Syntax
The syntax of <xsl:template> is as follows
<xsl:template
name=Qname
match=Pattern
priority=number
mode=QName>
</xsl:template>Attributes
The table describes the meaning of the attributes of <xsl:template>:
| Name | Description |
|---|---|
name |
Name of the element on which template is to be applied. |
match |
Pattern which signifies the element(s) on which template is to be applied. |
priority |
Priority number of a template. Matching template with low priority is not considered in from in front of high priority template. |
mode |
Allows element to be processed multiple times to produce a different result each time. |
