Editing XPath 2.0 (section)

== Other operators ==

Other operators available in XPath 2.0 include the following:

{|class="wikitable"
!Operators !! Effect
|-
| {{mono|+, -, *, div, mod, idiv}} ||Arithmetic on numbers, dates, and durations
|-
| {{mono|1==, !=, &lt;, &gt;, &lt;=, &gt;=}} ||General comparison: compare arbitrary sequences. The result is true if any pair of items, one from each sequence, satisfies the comparison
|-
| {{mono|eq, ne, lt, gt, le, ge}} ||Value comparison: compare single items
|-
| {{mono|is}} ||Compare node identity: true if both operands are the same node
|-
| {{mono|&lt;&lt;, &gt;&gt;}} ||Compare node position, based on document order
|-
| {{mono|union, intersect, except}} ||Compare sequences of nodes, treating them as sets, returning the set union, intersection, or difference
|-
| {{mono|and, or}} || boolean conjunction and disjunction. Negation is achieved using the <code>not()</code> function.
|-
| {{mono|to}} || defines an integer range, for example <code>1 to 10</code>
|-
| {{mono|instance of}} || determines whether a value is an instance of a given type
|-
| {{mono|cast as}} || converts a value to a given type
|-
| {{mono|castable as}} || tests whether a value is convertible to a given type
|}

Conditional expressions may be written using the syntax {{code|1=if (A) then B else C}}.

XPath 2.0 also offers a <code>for</code> expression, which is a small subset of the [[FLWOR]] expression from [[XQuery]]. The expression {{code|2=xquery|1=for $x in X return Y}} evaluates the expression <code>Y</code> for each value in the result of expression <code>X</code> in turn, referring to that value using the variable reference <code>$x</code>.
