xml - What does node()|@* mean XSLT? -

i have seen being used in contect:

<xsl:template match="node()|@*"> <xsl:copy>   <xsl:apply-templates select="node()|@*"/> </xsl:copy>

this called identity transform. node()|@* matching child nodes (node() text,element,processing instructions,comments) , attributes (@*) of current context.
