[jira] Commented: (TIKA-516) Excel 5 files are inconsistently detected as either "application/msword" or "application/vnd.ms-excel"

["Nick Burch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-516?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12910075#action_12910075 ] 

Nick Burch commented on TIKA-516:
---------------------------------

Have you tried with a recent svn checkout / recent nightly build? Something similar to this was fixed since 0.7

Also, if you're working with container formats and detection, you might want to switch to using the ContainerAwareDetector - it can correctly detect the type of container based formats like word and excel even if it doesn't have the filename.

> Using the AutoDetectParser on an Excel 5 file inconsistently detects it as either "application/msword" or "application/vnd.ms-excel"
> See the following code:
> 	public static void main(String[] args) throws Exception {
> 		FileInputStream stream = null;
> 		try {
> 			for (int i = 0; i < 10; i++) {
> 				File file = new File("excel5.xls");
> 				stream = new FileInputStream(file);
> 				AutoDetectParser parser = new AutoDetectParser();
> 				Metadata metadata = new Metadata();
> 				metadata.set(Metadata.RESOURCE_NAME_KEY, file.getName());
> 				parser.parse(stream, new DefaultHandler(), metadata);
> 				System.out.println(metadata.get(Metadata.CONTENT_TYPE));
> 			}
> 		} finally {
> 			if (stream != null) {
> 				stream.close();
> 			}
> 		}
> 	}
> an example output is: 
> application/vnd.ms-excel
> application/msword
> application/msword
> application/vnd.ms-excel
> application/vnd.ms-excel
> application/vnd.ms-excel
> application/vnd.ms-excel
> application/msword
> application/vnd.ms-excel
> application/msword
> The excel 5 file I used is attached to this bug.
