Counter inside xsl for-each loop

Question

How to get a counter inside xsl for-each loop that would reflect the number of current element processed  For example my source XML is   lt books gt       lt book gt           lt title gt The Unbearable Lightness of Being  lt  title gt       lt  book gt       lt book gt           lt title gt Narcissus and Goldmund lt  title gt       lt  book gt       lt book gt           lt title gt Choke lt  title gt       lt  book gt   lt  books gt    What I want to get is    lt newBooks gt       lt newBook gt           lt countNo gt 1 lt  countNo gt           lt title gt The Unbearable Lightness of Being  lt  title gt       lt  newBook gt       lt newBook gt           lt countNo gt 2 lt  countNo gt           lt title gt Narcissus and Goldmund lt  title gt       lt  newBook gt       lt newBook gt           lt countNo gt 3 lt  countNo gt           lt title gt Choke lt  title gt       lt  newBook gt   lt  newBooks gt    The XSLT to modify    lt xsl stylesheet version  1 0  xmlns xsl  http   www w3 org 1999 XSL Transform  gt       lt xsl output method  xml  version  1 0  encoding  UTF-8  indent  yes   gt       lt xsl template match     gt           lt newBooks gt               lt xsl for-each select  books book  gt                   lt newBook gt                       lt countNo gt     lt  countNo gt                       lt title gt                           lt xsl value-of select  title   gt                       lt  title gt                   lt  newBook gt               lt  xsl for-each gt           lt  newBooks gt       lt  xsl template gt   lt  xsl stylesheet gt    So the question is what to put in place of      Is there any standard keyword or do I simply must declare a variable and increment it inside the loop   As the question is pretty long I should probably expect one line or one word answer

You can also run conditional statements on the Postion   which can be really helpful in many scenarios   for eg     lt xsl if test   position       1  gt         Show header only once      lt  xsl if gt
