Author: asiri Date: 2008-11-04 07:36:17 +0100 (Tue, 04 Nov 2008) New Revision: 13945 Added: sandbox/xwiki-plugin-officeimporter/src/main/java/com/xpn/xwiki/ plugin/officeimporter/filter/StyleFixFilter.java sandbox/xwiki-plugin-officeimporter/src/main/java/com/xpn/xwiki/ plugin/officeimporter/filter/TableFixFilter.java Log: JIRA : http://jira.xwiki.org/jira/browse/XAOFFICE-1 Introduced two fix filters. These filters pre-process the xhtml document so that rendering via xwiki 2.0 syntax renderer produces acceptable results.
