Subject [jira] Commented: (JCR-1530) MsPowerPointTextExtractor does not extract from PPTs with € sign
Date Thu, 10 Apr 2008 12:18:05 GMT

    [ https://issues.apache.org/jira/browse/JCR-1530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12587611#action_12587611

Alexander Klimetschek commented on JCR-1530:

Hmm, IMHO it shouldn't be Jackrabbit's concern to handle such "details", especially as text
extraction from binary files is not a mandatory aspect of the JCR API.

What about using Apache Tika? It aims to collect all the various extraction libraries and
self-built classes of the Apache project and to build a proper re-usable framework. It recently
pushed out its first release. Jukka, you probably know more about it - is it already useful
for Jackrabbit? You mentioned in JCR-1290 that this could be a task for Jackrabbit 1.5.

>          Issue Type: Bug

>    Affects Versions: 1.4
>            Reporter: Dirk Feufel
> The MsPowerPointTextExtractor class has a problem when reading PPTs when an € sign
is contained. All text following that sign is ignored. Perhaps the POI PowerPointExtractor
should be used instead of parsing the data by hand. As a side effect, this would simply the
code. Extracting could be done as follows:
> 	public Reader extractText(InputStream stream, String type, String encoding) throws IOException
> 		try {
> 			PowerPointExtractor extractor = new PowerPointExtractor(stream);
> 			return new StringReader(extractor.getText(true,true));
> 		} catch (RuntimeException e) {
> 			logger.warn("Failed to extract PowerPoint text content", e);
> 			return new StringReader("");
> 		} finally {
> 			try { stream.close(); } catch (IOException ignored) {}
> 		}
> 	}
