Hello List I have a model with a set of one or more <sector/> elements where the sum of the sector/@percentage attributes should always equal 100. how do I express this as a bind constraint?

Whoops! silly question! I was calculating on individuals i.e.<xforms:bind nodeset="sector/@percentage" constraint="sum(.) = 100" /> and not the nodeset :( <xforms:bind nodeset="sector/@percentage" constraint="sum(sector/@percentage) = 100" /> > -----Original Message----- > From: p....@in... > Sent: Sat, 4 May 2013 02:24:58 -0800 > To: xsl...@li... > Subject: [Xsltforms-support] constraint against the sum of a series of > attributes > > Hello List > > I have a model with a set of one or more <sector/> elements where the sum > of the sector/@percentage attributes should always equal 100. > > how do I express this as a bind constraint? > > Cheers > > Peter > > ____________________________________________________________ > FREE 3D EARTH SCREENSAVER - Watch the Earth right on your desktop! > Check it out at http://www.inbox.com/earth > > > > ------------------------------------------------------------------------------ > Get 100% visibility into Java/.NET code with AppDynamics Lite > It's a free troubleshooting tool designed for production > Get down to code-level detail for bottlenecks, with <2% overhead. > Download for free and get started troubleshooting in minutes. > http://p.sf.net/sfu/appdyn_d2d_ap2 > _______________________________________________ > Xsltforms-support mailing list > Xsl...@li... > https://lists.sourceforge.net/lists/listinfo/xsltforms-support ____________________________________________________________ GET FREE SMILEYS FOR YOUR IM & EMAIL - Learn more at http://www.inbox.com/smileys Works with AIM®, MSN® Messenger, Yahoo!® Messenger, ICQ®, Google Talk™ and most webmails |

Hi Alain, I hit a possible issue with the combination of the context() and name() function. The example at https://github.com/AlainCouthures/xsltforms/blob/master/testsuite/XForms1.1/Edition1/Chapt07/7.10/7.10.4/7.10.4.a.xhtml works fine (obviously). Line 67 reads: <xforms:setvalue ref="instance('fruitInstance')/bad-fruit" value="context()" /> Clicking 'apple' returns 'apple'. If I replace in line 67 with <xforms:setvalue ref="instance('fruitInstance')/bad-fruit" value="name()" /> it still is ok. Clicking 'apple' returns 'bad-fruit'. If however I replace line 67 with <xforms:setvalue ref="instance('fruitInstance')/bad-fruit" value="context()/name()" /> I expect to see 'fruit' when I click 'apple', but XSLTForms returns a warning, and the return string is empty. The same problem occurs with local-name(). What can be the problem? Thanks, Fred van Blommestein |

Because XSLTForms implements an XPath 1.0 engine, functions cannot be
used within a path.

For both XPath 1.0 and XPath 2.0, name() and local-name() are functions
which can have a node as parameter: "name(context())" and
"local-name(context())" work as expected.
Thank you for your feedbacks!
