The same in effect, yes, but the point in fxgrep is that with:

<xsl:template match="book[%@price]">
  ...
</xsl:template>

the price attribute could be bound to the variable *during* the
matching rather than after finding the node. This saves you from
having to scan the node and its relationships with other nodes more
than once, which is particularly useful as you get to use more complex
match patterns.

Anyway, I'm not particularly advocating the idea -- I wouldn't want to
see XSLT complicated in this way (after all, it's getting complicated
enough by XPath 2.0 without anything like this!) -- just thought it
was an interesting approach.

Cheers,

Jeni
