Re: [Xsltforms-support] FW: Load Time Performance improvement - It works!

[Stephen C. <Ste...@ut...>]

I don't use exist so cannot comment on that aspect.

However, resorting to parsing the whole generated javascript sounds like a bad idea, there is usually a way forward within the standard XForms functionality. 

A GET request can be built from within the form and then sent off to load another instance with dynamic query key-value pairs.

I think I have discussed Alain at one time, to put GET request parameters of the form request into a default model instance, so that they can be accessed from within the form to then load another 'real' instance using "xforms-model-construct-done" event.

Concerning caching of xsltforms transform. I was forced to do caching
of the transform as well because the transform takes about 2 min! the
caching is fine because I only need to update the location of the
model and the post URI. That said the search and replace operation to
do so is very slow with the xquery functions provided by eXistdb. It
is the major part of the load time now. If I only had to parse a
smaller piece of text than the whole generated javascript, or maybe
set the values in a separate piece of code. I think I could improve
load times dramatically.

I would need a way to replace or modify the submission and instance
objects created by

"new XFSubmission" and "new XFInstance"

Are there methods to do this? I am not very experienced in javascript,
so digging trough the javascript code is a bit over my head. Any
ideas?

If we create the output HTML beforehand, the time spent in transforming the xml to html can be saved. I used java saxon8 xslt transformer for our 104 K size form. Result is saved to a HTML page, which can be loaded directly.
