Hello All,
I have a task in which i am to read data of attachment file(which is an xml file). can somebody guide me how i can achieve this. Is there any InputStream related API?
Do you mean you want to get the marked file(your file name is xxxx.xml) via API?
Hello Chen,
Yes, basically i am using xml file for attachment, I am to read that xml tags in that file using APIs and generate UI based on those tags.
I don't know how to read it online, but you can download it.
cadDoc is the host of the attachments.
EPMDocument latest = (EPMDocument) wt.vc.VersionControlHelper.service .allVersionsOf(cadDoc).nextElement();
ContentHolder holder = ContentHelper.service.getContents(latest);
Vector contents = ContentHelper.getContentListAll(holder);
Then you can traverse the contents then find the attachment and download it.
ContentServerHelper.service.writeContentStream((ApplicationData) contents.get(i), fullPath);
I'm not sitting in front of my IDE, but I think this should about do it.
ContentHolder holder = (ContentHolder)new ReferenceFactory().getReference(String oid).getObject();
holder = wt.content.ContentHelper.service.getContents(holder);
final QueryResult contents = ContentHelper.service.getContentsByRole(holder,ContentRoleType.SECONDARY);
whlie(contents.hasMoreElements()) {
ContentItem ci = (ContentItem)contents.nextElement();
if(ci instanceof ApplicationData) {
ApplicationData ad = (ApplicationData)ci;
try(final InputStream is = wt.content.ContentServerHelper.service.findContentStream(ad)) {
//get file info from ad
final File temp = File.createTempFile("xxx","xxx");
FileUtils.copyInputStreamToFile(is, temp);
}
}
}
