XML Set Value

XML Set Value

Type: xml-set-value  ·  Package: XML Activities v1.0.0  ·  Output: string

Change the text value of the first element that matches an XPath and return the modified XML. Use it to update data in an XML document: a status, a date, an amount.

How it works

Locates the first element that matches xpath in xml, puts the new value in it, and returns the complete modified XML (as a string). Remember to save the result with Write XML.

Required parameters

Parameter	Editor	Description
xml	expression	The XML text.
xpath	expression	XPath to the element to update.
value	expression	The new value.

Optional parameters

Ninguno.

Output

Returns a string with the modified XML.

Example

Read XML   path = = ruta   → output: xml
XML Set Value   xml = = xml   xpath = "//Factura/Estado"   value = "Pagada"   → output: xmlNuevo
Write XML   path = = ruta   content = = xmlNuevo

Returns the XML, does not modify the file

Set Value works on the text: it returns the changed XML, but does not touch the file. To persist the change, pass its output to Write XML.
