ok, I've made some progress here. the page mentioned calls a script from: http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/scripts/Bibsonomy
Which is also available here: http://code.xwiki.org/xwiki/bin/view/Macros/BibsonomyMacro that script pulls data from bibsonomy.org using RSS and parses the feed: #set($feed = $xwiki.feed.getFeeds(" http://www.bibsonomy.org/publrssN/tag/${tag}?items=1000";)) #foreach ($entry in $feed.entries) #set($val = $entry.getDescription().value) ## get title #set($index = $val.indexOf("bmtitle") +10) #set($val = $val.substring($index)) #set($index = $val.indexOf("</div>")) #set($headline = $val.substring(0, $index)) #set($index = $index +6) #set($val = $val.substring($index)) ugly hack, but I was in a rush to get the feature out.. As was bound to happen at some point, the format of the feed content has changed, and the code is now broken. As a quick fix, I replaced it with: #set($feed = $xwiki.feed.getFeeds(" http://www.bibsonomy.org/publrssN/tag/${tag}?items=1000";)) #foreach ($entry in $feed.entries) $entry.getDescription().value) I don't know if the change in the feed format is on the provider's side (i.e. bibsonomy) or on XWiki's side. In any case, I should use bibsonomy's API instead: http://www.bibsonomy.org/help/doc/api.html Anyone interested in helping? ___________________________ Yishay Mor, Researcher, London Knowledge Lab http://www.lkl.ac.uk/people/mor.html http://www.google.com/calendar/embed?src=yishaym%40gmail.com +44-20-78378888 x5737 2009/1/22 Yishay Mor <[email protected]> > This: > > http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/scripts/BibsonomyDemo > used to work, now it throws a vicious exception - I can't even track down > the line number. any ideas? > > org.apache.velocity.exception.MethodInvocationException: Invocation of > method 'exists' in class com.xpn.xwiki.api.XWiki threw exception > java.lang.StringIndexOutOfBoundsException: String index out of range: -16 @ > scripts.BibsonomyDemo31,15? > > > ___________________________ > Yishay Mor, Researcher, London Knowledge Lab > http://www.lkl.ac.uk/people/mor.html > http://www.google.com/calendar/embed?src=yishaym%40gmail.com > +44-20-78378888 x5737 > _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
