## Properties

| Property | Value |

| Access | Public |

## Procedures

- `TryValidateAgainstSchema(Xml: Text; XmlSchema: Text; Namespace: Text)`: Performs validation of an XML from a string against a schema from a string.
- `TryValidateAgainstSchema(XmlDoc: XmlDocument; XmlSchemaDoc: XmlDocument; Namespace: Text)`: Performs validation of a XmlDocument against a schema in a XmlDocument.
- `TryValidateAgainstSchema(XmlDocInStream: InStream; XmlSchemaInStream: InStream; Namespace: Text)`: Performs validation of a XmlDocument against a schema in a stream.
- `TrySetValidatedDocument(Xml: Text)`: Sets validated document from a string.
- `TrySetValidatedDocument(XmlDoc: XmlDocument)`: Sets validated document in a XmlDocument.
- `TrySetValidatedDocument(XmlDocInStream: InStream)`: Sets validated document from a stream.
- `TryAddValidationSchema(Xml: Text; Namespace: Text)`: Adds validation schema to validated document from a string.
- `TryAddValidationSchema(XmlSchemaDoc: XmlDocument; Namespace: Text)`: Adds validation schema to validated document in a XmlDocument.
- `TryAddValidationSchema(XmlSchemaInStream: InStream; Namespace: Text)`: Adds validation schema to validated document from a stream.
- `TryValidateAgainstSchema()`: Performs validation of a XML document against one or multiple XSD schemas.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 6241 "Xml Validation Impl."](../codeunit/6241.md) (3 calls: `TryAddValidationSchema → AddValidationSchema`, `TrySetValidatedDocument → SetValidatedDocument`, `TryValidateAgainstSchema → ValidateAgainstSchema`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Xml Validation")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
