Desktop software to extract simple spun article

I want a desktop software to extract simple spun (1st level spun) article. The spun article will be in this format; {sentence1A|sentence1B}. {sentence2A|sentence2B}. {sentence3A|sentence3B}. This should be separated into 2 different articles, like; 1st Article - sentence1A. sentence2A. sentence3A 2nd Article - sentence1B. sentence2B. sentence3B and be saved in 2 different doc files. The software should be able to extract simple spun article of upto 5 sentences. I am attaching a sample simple spun article. Please contact me for any further clarification.
