MxParser (Prowide Core API Reference)

java.lang.Object
- com.prowidesoftware.swift.io.parser.MxParser

```
public class MxParser
extends java.lang.Object
```
Basic parser for MX messages.
IMPORTANT: An MX message is conformed by a set of optional headers and a message payload or document with the actual specific MX message. The name of the envelope element that binds a Header to the message to which it applies is implementation/network specific and not part of the scope of the parser.
This parser has three main utilities;
1. The first one to convert the message into an MxNode tree. This is a generic structured representation of the complete content that can be used to get specific items by xpath. It parses the complete tree including both payload and overhead information (wrappers, if any, application header and body content).
2. The second utility is to parse the application header extract of the XML into a model object. Notice the application header is mainly used to identify the specific message, and two versions are supported; the legacy SWIFT ApplicationHeader and the ISO BusinessApplicationHeaderV01.
3. The third one is to provide convenient API to detect the specific Mx message type, to analyze the payload structure and to strip the document or header portions from the XML in a lightweight and efficient way.
Notice that support for MX in Prowide Core is limited. Complete model and parser implementation for each MX message type is implemented into subclasses of AbstractMX by Prowide Integrator.

  - parseBusinessHeader
```
public BusinessHeader parseBusinessHeader()
```
    Detects the type of header and parses it as a legacy SWIFT Application Header or ISO Business Application Header. Uses the namespace (if present) or an heuristic based on tags names.
    By default ISO Business Application Header is expected and assumed for the AppHdr tag.
    
    Returns:
    
    parsed header or null if the content cannot be parsed or the header is not present in the XML
  - parseBusinessHeader

public static BusinessHeader parseBusinessHeader(org.w3c.dom.Element e)

  - detectMessage
```
public MxId detectMessage()
```
    Takes an xml with an MX message and detects the specific message type parsing just the namespace from the Document element. If the Document element is not present, or without the namespace or if the namespace url contains invalid content it will return null.
    Example of a recognizable Document element:
    <Doc:Document xmlns:Doc="urn:swift:xsd:camt.003.001.04" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    The implementation is intended to be lightweight and efficient, based on XMLStreamReader
    
    Returns:
    
    id with the detected MX message type or null if it cannot be determined.

  - analizeMessage
```
@Deprecated
 @ProwideDeprecated(phase3=SRU2020)
public MxParser.MxStructureInfo analizeMessage()
```
    Deprecated. use analyzeMessage() instead
    
    Since:
    
    7.8.4
  - analyzeMessage
```
public MxParser.MxStructureInfo analyzeMessage()
```
    Convenient API to get structure information from an MX message.
    This can be helpful when the actual content of an XML is unknown and some preprocessing of the XML must be done in order to parse or validate its content properly.
    The implementation is intended to be lightweight and efficient, based on XMLStreamReader
    If the message contains more than one Document element, the first one will be picked. The same applies for the header, only the first AppHdr will be picked
    
    Since:
    
    7.10.3
  - getBICFromDN
```
public static java.lang.String getBICFromDN(java.lang.String dn)
```
    Distinguished Name structure: cn=name,ou=payment,o=bank,o=swift
    Example: o=spxainjj,o=swift
    
    Parameters:
    
    dn - the DN element content
    
    Returns:
    
    returns capitalized "bank", in the example SPXAINJJ
  - stripDocument
```
public java.lang.String stripDocument()
```
    Helper API to strip Document portion of message XML.
    This API is convenient when only the Document element of an MX message is needed and the wrapper/payload structure is unknown.
    This implementation is intended to be lightweight and efficient so it actually does a simple substring operation on the XML using information provided by the result of analyzeMessage(). The XML is not converted into DOM.
    If the message contains more than one Document element the expected result is as follows:
    - If the documents are nested (this can happen for example when an additional MX message is provided within a supplementary data element within the main MX) then the outermost Document will be returned.
    - If the documents are not-nested (weird situation) the result might be not well-formed
    Returns:
    
    XML with Document element of the Mx message or null if message is blank or invalid
    
    Since:
    
    7.8.4
  - stripHeader
```
public java.lang.String stripHeader()
```
    Helper API to strip AppHdr portion of message XML.
    This API is convenient when only the header element of an MX message is needed and the wrapper/payload structure is unknown.
    To gather the header already parsed into objects see parseBusinessHeader()
    This implementation is intended to be lightweight and efficient so it actually does a simple substring operation on the XML using information provided by the result of analyzeMessage(). The XML is not converted into DOM.
    If the message contains more than one AppHdr element the expected result is as follows:
    - If the headers are not nested, the first one will be returned.
    - If the headers are nested (weird situation) the result might be not well-formed
    Returns:
    
    XML with AppHdr element of the Mx message or null if not found
