Increment

Hello, I want to increment a variable in for-each loop. I could use
"<xsl:value-of select="position()" />" if it is a direct one. But my
requirement can be summarized as follows:

declare count
for-each()
{
	if(something)
	{
		increment count
	}
	else
	{
		nothing
	}
}

can anyone please help me out.
