RE: concat string

Hi YueMa,

I'm an XSLT newbie myself, but I think these should work.

Below are two slightly different ways of achieving the output:

> <META http-equiv="Keywords" name="Keywords" content="key1, 
> key2, key3">

from your source:

> ..
> <keys>key1</keys>
> <keys>key2</keys>
> <keys>key3</keys>
> ..

'method1' uses a template to match on 'keys' and uses xsl:attribute .
'method2' uses xsl:for-each and xsl:variable.

Note: both methods match on ALL 'keys' which may not be what you want.

Regards,
Jon.
