<xsl:attribute
name="attribute-name" >
</xsl:attribute>
Attributes
name
Name of the attribute to create.
Element Information
| Number of occurrences | Unlimited |
| Parent elements | xsl:copy, xsl:element, xsl:for-each, xsl:if, xsl:otherwise, xsl:template, xsl:when, output elements |
| Child elements | xsl:choose, xsl:copy, xsl:eval, xsl:for-each, xsl:if, xsl:value-of |
| Requires closing tag | Yes. XSL is an XML grammar and, like all XML grammars, all tags must have closing tags to satisfy the definition of well-formed. |
Remarks
The contents of this element specify the value of the attribute.
Attributes can be added or modified during transformation by placing the xsl:attribute element within elements that generate output, such as the xsl:copy element. Note that xsl:attribute can be used directly on output elements, and not only in conjunction with xsl:element.
All attributes must be applied before children are added to the element.
Examples
This example generates an attribute that obtains its value from the XML source. It generates output in the form <IMG src="value-from-XML-source" />, using an XSL pattern that retrieves the appropriate data from the XML source, here "imagenames/imagename".
<IMG>
<xsl:attribute name="src">
<xsl:value-of select="imagenames/imagename" />
</xsl:attribute>
</IMG>
This example copies the "myElement" element and adds a "copied" attribute with the value "true".
<xsl:template match="myElement">
<xsl:copy>
<xsl:attribute name="copied">true</xsl:attribute>
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
