[Xerte] Re: Page linking from external website

[Kemp Johnathan]

If the original project that lead to this request is in XOT then unless the
original page model was based on using a framework there would be no
framework involved and hence no nested page? You are right that XOT just
offers you pre-built page types. So all you would need to do is to edit the
template.rlt file to add the code to detect the page url and navigate to it
(plus adding the javascript function to the rlsObject.js file).

If the project is in desktop Xerte then my worked example should enable the
project author to identify the page from the url.

My earlier comments of adding code to the page that contains the framework
to detect a nested page value in the url might then solve the rest of the
problem of identifying from the url the identifier for the nested page and
then navigating to it within the framework.

Kind regards

Johnathan
