XPath function
substring-after()
Everything after the first occurrence of a marker. Empty when the marker is absent.
substring-after(s, m) returns the part of s that follows the first m. Paired with substring-before() it splits a two-part value.
Chaining them is how you reach later fields: substring-after(substring-after(s, '-'), '-') gets past two delimiters.

Worked examples
Each result below is what the evaluator returned, asserted on every test run. An empty result means an empty node-set — which is an answer, not an error.
The sample documents
Every example on this page runs against this document. The sitemap one is namespaced on purpose — almost every real XML document is, and that changes which expressions match.
<?xml version="1.0" encoding="UTF-8"?>
<order id="A-1001" tier="gold">
<customer country="NO">Ada Lovelace</customer>
<!-- priority customer -->
<?audit retained?>
<lines>
<line sku="WIDGET-1" qty="2"><price>14.50</price></line>
<line sku="WIDGET-2" qty="1"><price>39.00</price></line>
<line sku="GIFT-WRAP" qty="1"><price>0.00</price></line>
</lines>
<note> Deliver after 09:00 </note>

- substring-before()Everything before the first occurrence of a marker — and the empty string when the marker is absent, which is not an error you will notice.
- substring()A slice of a string, indexed from 1 — not from 0, which is the mistake that shifts every result by one character.
- contains()Whether one string occurs inside another. The most-used XPath function, and the one most often given its arguments the wrong way round.
