  • 0

I want to get the index of a node using XPath, but I’d love to do it in a single line. I want the int that I’m storing to double as proof of existence of the node, and the position of the FIRST occurrence of a matching node.

What I have now does what I want, but it matches the LAST occurrence of a matching node instead of the first. Can I alter this to get me the first one?

    Are you looking for the position() function?

    Try /configuration / Security / Authentication / schemes [@type = 'ssoscheme, sso'] / preceding-sibling::scheme / position().
