Power Automate (WDL) function

xpath — Power Automate (WDL) function reference

Query an XML document.

Syntax

wdl

xpath(xml, expression)

wdl

xpath(xml(body('HTTP')), '//title/text()')

→ Matching nodes

wdl

xpath(xml(body('HTTP')), 'string(//Invoice/Total/text())')

→ A plain string value, e.g. "1250.00"

wdl

xpath(xml(triggerBody()?['content']), '//Item/@sku')

→ An array of matching sku attribute nodes

xpath() returns an array of XML nodes by default, even for a single match — wrap the XPath expression itself in string(...) when you need a plain string result instead of a node array.
The input must already be XML, typically produced by xml() — passing raw text without parsing it first throws.
