Codec Xml via Xsd (2.4.0)

How it works:

Codec operates with message groups whom may contain a mix of raw and parsed messages.

Encoding

During encoding codec must replace each parsed message of empty or supported protocol in a message group with a raw one by encoding parsed message's content.

Decoding

During decoding codec must replace each raw message of empty or supported protocol in a message group with a parsed one by decoding raw message's content.
Attributes from xml will be parsed as fields with '-' at start of field name, as example "-attributeName":"attributeValue".
If field had attributes with value inside, value will be converted into field #text.

As example:

---

<test f="456">some data</test>

into

addField("test", message().apply {
    addFields("-f", "456")
    addFields("#text", "some data")
})

---

and

---

<h>A</h>

into

addField("h", "A")

---

All xml messages must have schemaLocation due validation. Xsd schema will be found in archive using this parameter.

Configuration

Codec must be linked to dictionary. Dictionary is set of compressed xsd files. Zip archive must be converted to base64 and filled like a standard dictionary with converted data.
Error from validation process can be disabled for test purposes by dirtyValidation option.

Configuration example

• typePointer - Path to message type value for decode (null by default)
• dirtyValidation - Disable/enable error during validation phase. If disabled all errors will be only visible in log (false by default)
• schemas - mapping between schema location value and a dictionary alias that should be used to load this schema

typePointer: /root/node/node2/type
dirtyValidation: false
schemas:
  "test.xsd": "${dictionary_link:dict-xml}"

For example:

apiVersion: th2.exactpro.com/v1
kind: Th2Box
metadata:
  name: codec-xml-xsd
spec:
  custom-config:
    codecSettings:
      typePointer: /root/node/node2/type

Required pins

Every type of connection has two subscribe and publish pins. The first one is used to receive messages to decode/encode while the second one is used to send decoded/encoded messages further. Configuration should include at least one pin for each of the following sets of attributes:

• Pin for the stream encoding input: encoder_in parsed subscribe
• Pin for the stream encoding output: encoder_out raw publish
• Pin for the general encoding input: general_encoder_in parsed subscribe
• Pin for the general encoding output: general_encoder_out raw publish
• Pin for the stream decoding input: decoder_in raw subscribe
• Pin for the stream decoding output: decoder_out parsed publish
• Pin for the stream decoding input: general_decoder_in raw subscribe
• Pin for the stream decoding output: general_decoder_out parsed publish

Configuration example

apiVersion: th2.exactpro.com/v1
kind: Th2Box
metadata:
  name: codec-xml-xsd
spec:
  image-name: ghcr.io/th2-net/th2-codec-xml-via-xsd
  image-version: #lastVersion
  type: th2-codec
#  custom-config:
#    codecSettings:
#      typePointer: /root/node/node2/type
#      dirtyValidation: false
  pins:
    # encoder
    - name: in_codec_encode
      connection-type: mq
      attributes: [ 'encoder_in', 'parsed', 'subscribe' ]
    - name: out_codec_encode
      connection-type: mq
      attributes: [ 'encoder_out', 'raw', 'publish' ]
    # decoder
    - name: in_codec_decode
      connection-type: mq
      attributes: ['decoder_in', 'raw', 'subscribe']
    - name: out_codec_decode
      connection-type: mq
      attributes: ['decoder_out', 'parsed', 'publish']
    # encoder general (technical)
    - name: in_codec_general_encode
      connection-type: mq
      attributes: ['general_encoder_in', 'parsed', 'subscribe']
    - name: out_codec_general_encode
      connection-type: mq
      attributes: ['general_encoder_out', 'raw', 'publish']
    # decoder general (technical)
    - name: in_codec_general_decode
      connection-type: mq
      attributes: ['general_decoder_in', 'raw', 'subscribe']
    - name: out_codec_general_decode
      connection-type: mq
