Este programa converte arquivos XML em um formato TXT customizado, ou seja, o código <elemento chave1="valor1" chave2="valor2">Texto</elemento> é "transformado" em:

"ELEMENTO[ chave1="valor1" chave2="valor2" ]: Texto /ELEMENTO".

Versão 2 - Enviado por Talvanes Ferreira de Sousa em 26/08/2014

Changelog:
Xml2Txt(v. 2.1): A utility to convert XML files into a hierarchical-based TXT format. Also performs batch conversion.

Usage:
Xml2Txt [--working-dir/-w work_dir] [--dest-dir/-d dest_dir] file1.xml file2.xml file3.xml (...)
Xml2Txt --help/-h
Xml2Txt --version/-v

where:
--working-dir/-w: working directory, where all XML files must be. By default, it is in the same directory as the executable program (exec_dir);
--dest-dir/-d: destination directory, where all resulting ".xml.txt" files will be placed into. By default, it is also exec_dir;
file1.xml file2.xml file3.xml (...): one or more XML files that are going to be processed in the working dir. This is mandatory;
--help/-h: shows program help;
--version/-v: shows software version.


Traduzindo:


Xml2Txt(v. 2.1): Um utilitário para converter arquivos XML em um formato de texto hierarquizado. Também converte em série.

Uso:
Xml2Txt [--working-dir/-w work_dir] [--dest-dir/-d dest_dir] file1.xml file2.xml file3.xml (...)
Xml2Txt --help/-h
Xml2Txt --version/-v

Onde:
--working-dir/-w: diretório de trabalho (ou de origem), onde todos os XML deverão estar. Por padrão, é no mesmo diretório do programa executável (exec_dir);
--dest-dir/-d: diretório de destino, onde todos os arquivos ".xml.txt" resultantes serão colocados. Por padrão, também é exec_dir;
file1.xml file2.xml file3.xml (...): sequência de um ou mais arquivos XML que serão processados no diretório de trabalho. Obrigatório;
--help/-h: exibe a ajuda do programa;
--version/-v: exibe a versão do programa.
