Hi,I have a workflow which sends ms-word/powerpoint/pdf/excel for approval to a pool of users.Once approved, i need to extract content from the document in an XML file. I tried this code for content transformation:
…
contentService = services.getContentService();
ContentReader reader = contentService.getReader(nodeRef, ContentModel.PROP_CONTENT);
if (reader != null && reader.exists())
{
// get the transformer
ContentTransformer transformer = contentService.getTransformer(reader.getMimetype(), MimetypeMap.MIMETYPE_TEXT_PLAIN);
// is this transformer good enough?
if (transformer != null)
{
// We have a transformer that is fast enough
ContentWriter writer = contentService.getTempWriter();
writer.setMimetype(MimetypeMap.MIMETYPE_TEXT_PLAIN);
try
{
transformer.transform(reader, writer);
// point the reader to the new-written content
reader = writer.getReader();
// Check that the reader is a view onto something concrete
if (!reader.exists())
{
throw new ContentIOException("The transformation did not write any content, yet: \n"
+ " transformer: " + transformer + "\n" + " temp writer: " + writer);
}else {
content = reader.getContentString();
}
}
catch (ContentIOException e)
{
}
}
}
logger.debug("Content as a string : "+content);
…
It gives me content of document as a string but also creates a text file with same name as content which i do not want & nullifying purpose of workflow. How can i avoid that.I have read that transformation of content will result into file creation. 😎 Also the content i got in previous step is not purely text, it contains characters like   and a lots like this in formed XML which my external application fails to parse. 
How can i fulfill my requirement.Would appreciate for any help/suggestions.
