Hello Ron,
Yes, it is feasible to do the metadata extraction upstream of MarkLogic. It complicates things a little bit but it will be ok. Apache Tika looks like a nice solution. My client is a Microsoft shop and they use a product called Aspose to convert/extract data from spreadsheets. The majority of spreadsheet formats that I need to ingest use the older 97/2003 format. I can use the Aspose API to covert the older format to OOXML on the fly. It's unfortunate that the MarkLogic xdmp:document-filter() API is not able to extract the "defined name" metadata from the "97/2003" file format. I consider it to be a bug in the MarkLogic API because other Excel Spreadsheet extraction APIs (e.g., Aspose, Tika, Apache POI) can extract this data from the older file format. Anyway, thanks for the info. - Gary R From: [email protected] [mailto:[email protected]] On Behalf Of Ron Hitchens Sent: Friday, October 17, 2014 11:52 AM To: MarkLogic Developer Discussion Subject: Re: [MarkLogic Dev General] Is there a way to extract worksheet metadata from an Excel 97/2003? If it's feasible to do your metadata extraction upstream of MarkLogic (i.e., before insertion) you might take a look at Apache Tika. It's designed for this sort of thing. You could also setup it up in a simple web service callable from MarkLogic. POST the spreadsheet to it and have it return the metadata in whatever form you like. --- Ron Hitchens {[email protected]} +44 7879 358212 On Oct 17, 2014, at 3:35 PM, Gary Russo <[email protected]> wrote: Hello Dennis, Thanks for the info. Yes, I tried xdmp:excel-convert() but this does not get the worksheet metadata either. The metadata that I need to retrieve from the older excel format is the "Named Fields". Users create them using the Excel "Named Box" feature as shown here. => <http://spreadsheets.about.com/od/exceltips/qt/81225namebox.htm> http://spreadsheets.about.com/od/exceltips/qt/81225namebox.htm It looks like my only option is to use the Apache POI Java API to extract the named fields or use it to convert xls-to-xlsx on-the-fly. => <https://poi.apache.org/apidocs> https://poi.apache.org/apidocs I know there's a hidden way to use MarkLogic's underlying JVM. It would be great if I could use it to call the Apache POI code. But that's a question for another day.

HI. I believe that with the conversion licence, you can do what you want with: xdmp:excel-convert Barring that, you could always run openoffice as a headless server for conversion purposes.

The ISYS xdmp:document-filter() API is limiting because it only extracts the text. It does not extract any worksheet metadata. Does anyone know of a workaround for this? My only thought is to upload the "Excel 97/2003" xls file and then convert it on the server to an "Excel 2010" xlsx format. Once it's in an Excel 2010 format, I can easily extract the "defined name" metadata. This is what it looks like in "Excel 2010" files. <definedNames> <definedName name="LastYr">Revenue!$B$6:$B$15</definedName> <definedName name="ThisYr">Revenue!$C$6:$C$15</definedName> <definedName name="Variance">Revenue!$D$6:$D$15</definedName> </definedNames> Thanks, Gary Russo Gary Russo Enterprise NoSQL Developer Phone: <tel:212-404-8639> 212-404-8639 Skype: garyprusso <http://garyrusso.wordpress.com> http://garyrusso.wordpress.com _______________________________________________ General mailing list <mailto:[email protected]> [email protected] <http://developer.marklogic.com/mailman/listinfo/general> http://developer.marklogic.com/mailman/listinfo/general _______________________________________________ General mailing list <mailto:[email protected]> [email protected] <http://developer.marklogic.com/mailman/listinfo/general> http://developer.marklogic.com/mailman/listinfo/general
