Hi,
I'm fairly new to all of this myself, but my guess would be that there
are two things wrong with the script.
1. you need a syncronous call to fill the xml at the start (now it's
asynchronous and the xml might not be read when you call
findProjectAnchor
2. the line:
var datascapeAnchorsXml = $(xmlData);
fills a local variable, within the function scope, the line
var thisDS = datascapeAnchorsXml.find('scape[title="' + scape +
'"]');
seems to be reading a global variable.
Hope this helps,
Groeten,
Friso
