Re: [xsl] count Nodes with attributes until... (XSLT 1.0)

[George Cristian Bina <george@xxxxxxxxxxxxx>]

You can count the number of following siblings that have the count-me 
attribute set to yes and remove the nodes to be counted after the first 
node that does not have a count-me equals with yes attribute:

count(following-sibling::*[@count-me='yes'])- 
count(following-sibling::*[not(@count-me='yes')][1]/following-sibling::*[@count-me='yes'])

Best Regards,
George
