How do I select the position of a following sibling.

Question

I need to select the position of a following sibling via XSL.

This is not working:

<xsl:variable name="nextAnswerListItemPos" select="following-sibling::*[local-name() = 'AnswerListItem'][position()]" />

Answer 1

<xsl:variable name="nextAnswerListItemPos" select="count(following-sibling::*[local-name() = 'AnswerListItem'][1]/preceding-sibling::*) + 1" />
