# Validator
|
|
|
|
The validator is an XML validation-engine. It validates XML documents against XML Schema and Schematron Rules depending on self defined [scenarios](docs/configurations.md) which are used to fully configure the validation process.
|
|
The validator always outputs a [validation report in XML](docs/configurations.md#validators-report) including all validation errors and data about the validation.
|
|
|
|
See [architecture](docs/architecture.md) for informations about the actual validation process.
|
|
|
|
## Packages
|
|
|
|
The validator distribution contains the following artifacts:
|
|
|
|
1. **validationtool-`<version>`.jar**: Java library for embedded use within an application
|
|
1. **validationtool-`<version`>-standalone.jar**: Uber-JAR for standalone usage containing all dependencies in one jar file. This file comes with JAXB *embedded* and can be used with Java 8 and Java >= 11)
|
|
1. **validationtool-`<version`>-java8-standalone.jar**: Uber-JAR for standalone usage with Java JDK 8 containing all dependencies in one jar file. This file file *does not* contain JAXB and depends on the bundled version of the JDK.
|
|
1. **libs/***: directory containing all (incl. optional) dependencies of the validator
|
|
|
|
|
|
## Validation Configurations
|
|
|
|
The validator is just an engine and does not know anything about XML Documents and has no own validation rules.
|
|
Validation rules and details are defined in [validation scenarios](docs/configurations.md) which are used to fully configure the validation process.
|
|
All configurations are self-contained modules which are deployed and developed on their own.
|
|
|
|
### Third Party Validation Configurations
|
|
|
|
Currently, there are two public third party validation configurations available.
|
|
|
|
* Validation Configuration for [XRechnung](http://www.xoev.de/de/xrechnung):
|
|
* Source code is available on [GitHub](https://github.com/itplr-kosit/validator-configuration-xrechnung)
|
|
* [Releases](https://github.com/itplr-kosit/validator-configuration-xrechnung/releases) can also be downloaded
|
|
* Validation Configuration for [XGewerbeanzeige](https://xgewerbeanzeige.de/)
|
|
* Source code is available on [GitHub](https://github.com/itplr-kosit/validator-configuration-xgewerbeanzeige)
|
|
* [Releases](https://github.com/itplr-kosit/validator-configuration-xgewerbeanzeige/releases) can also be downloaded
|
|
|
|
## Usage
|
|
|
|
The validator is designed to be used in three different ways:
|
|
|
|
* as standalone application running from the cli
|
|
* as library embedded within a custom application
|
|
* as a daemon providing a http interface
|
|
|
|
### Standalone Command-Line Interface
|
|
|
|
The general way using the CLI is:
|
|
|
|
```shell
|
|
java -jar validationtool-<version>-standalone.jar -s <scenario-config-file> [OPTIONS] [FILE] [FILE] [FILE] ...
|
|
```
|
|
|
|
The help option displays further CLI options to customize the process:
|
|
|
|
```shell
|
|
java -jar validationtool-<version>-standalone.jar --help
|
|
```
|
|
|
|
A concrete example with a specific validator configuration can be found on
|
|
[GitHub](https://github.com/itplr-kosit/validator-configuration-xrechnung)
|
|
|
|
### Application User Interface (API / embedded usage)
|
|
|
|
The validator can also be used in own Java Applications via the API. An example use of the API as follows:
|
|
|
|
```java
|
|
Path scenarios = Paths.get("scenarios.xml");
|
|
Configuration config = Configuration.load(scenarios.toUri());
|
|
Input document = InputFactory.read(testDocument);
|
|
|
|
Check validator = new DefaultCheck(config);
|
|
Result validationResult = validator.checkInput(document);
|
|
|
|
// examine the result here
|
|
```
|
|
|
|
The [API documentation](./docs/api.md) shows further configuration options.
|
|
|
|
### Daemon-Mode
|
|
|
|
You can also start the validator as a HTTP-Server. Just start it in _Daemon-Mode_ with the `-D` option.
|
|
|
|
```shell
|
|
java -jar validationtool-<version>-standalone.jar -s <scenario-config-file> -D
|
|
```
|
|
|
|
|
|
The [daemon documentation](./docs/daemon.md) shows more usage details and further configuration options.
