XSLT-Xpath比较属性

Question

can any one explain me the difference between

<xsl:template match="a/@ref[.='attr']">

and

<xsl:template match="a[@ref='attr']">

is this template matches the same thing or different thing?

Answer 1

The first template is selecting the attribute ref .

The second template is selecting the element a .

Both have a predicate that requires the attribute ref to equal attr .
