XSLTProcessor: reset() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The reset()
method of the XSLTProcessor
interface removes all parameters (<xsl:param>
) and the XSLT stylesheet from the processor. The XSLTProcessor
will then be in its original state when it was created.
Syntax
js
reset()
Parameters
None.
Return value
None (undefined
).
Examples
Using reset()
This example demonstrates how the reset()
method allows the same XSLTProcessor
instance to be reused for multiple transformations with different stylesheets.
