and even if it would return on time (synchronous call) you wouldn't
really return it with datascape.getAllAnchors (return is wrapped
inside the get object).
This might or might not work depending on the timing:
datascape.getAllAnchors = function(anchors){
$.get("projects/datascapes.xml",function(data){
anchors = $(data);
});
}
depends on how fast you need it, but it's better to wrap everything in
a function that only gets executed once the data has been completely
loaded?
function dosomething(data){
var xx = data..... etc
var thisDS = $('scape[title="'+UI.section+'"]', datascape.anchors);
var dsAnchorVar = $('item[title="' + $proj +
'"]',thisDS).parents('col').attr('title');
$.log("anchor "+$proj+"= "+ dsAnchorVar );
}
$.get("projects/datascapes.xml",dosomething);

(stored in the xml file) that i will query many times, with different
parameters. But with your various replies you already showed me more or less
howto do it, i'll try to work it out , thanks again
