Default Difference between call-template ,apply-templates

Is there any different between the <xsl:call-template> and <xsl:apply-templates> other than their attributes. Also is there any thing related to performance for these two elements. Thanks in advance for the help.

In terms of raw performance xsl:call-template is likely to be faster, as you are calling a specific named template, rather than telling the XSLT processor to pick the template which best matches.

There are certainly things you can do with xsl:call-template that you can't do with xsl:apply-templates, such as recursive templates which are very powerful.

xsl:apply-templates is however the more flexible and extensible, due to its combined use of the match patterns, modes and priorities.

Yes, there are lots of differences. With call-template you have to know what you're calling. apply-templates is polymorphic - what gets called depends on what you find in the input, which means it is the key feature that enables XSLT to respond to variable or unpredictable input - essential when handling documents as distinct from structured data.

Actually, recursion using apply-templates can be even more powerful - and is often overlooked.
