Hello, Pierre. The XML output is raw xml and has no formatting as you have found, when displayed in a browser. Typically it gets processed by a web app that can read the xml and display as HTML (with or without CSS). You can also EXPORT XML and apply an XSLT to transform to a text, html or other xml format.
Perhaps you need to use the same logic to find, sort and report (on a layout) what you have gotten with CWP calls? Or is the real need to have someone (without FMP, without connection to FMS) to see a web page of your data? Can it be exported as Excel or as PDF that can be seen, instead?
A little more thought, please?
Yes the real need is.. My page should be parseable by a normal browser, so that employees can consult these pages statically with their Android, our iPad or just any browser.
OK, then I suggest taking the CWP to php or other web app and process the query result (converting to HTML that can be viewed in any browser).
But it depends on your web server setup. Go back to the CWP guide and study chapter 6 (p. 59)
