# XSD validator

### Description

The `XSD validator` validates an XML files against an internal (defined in the XML file) or external (defined in a separate xsd file) XML schema.

XSD is short for [XML Schema](http://en.wikipedia.org/wiki/XML_Schema_\(W3C\)) Definition.

As such, there are 2 entities at work here:

* The XML you want to validate the layout for
* The XSD (Schema) file that describes what the XML file should look like.

See also the [XSD Validator pipeline transform](/data-shaper-1.21/knowing-the-data-shaper-designer/pipelines/transforms/xsdvalidator.md).
