XML data structure for Tree

[markgoldin]

I am looking into tree binding examples. All xml data is shown as an element based. Can I bind a tree widget to an attribute based xml?

Thanks

Yes - you can use attributes or sub-elements for atomic values in your XML.

attributes in XML to be in a Tree

I am having the same question.
Basically, I have a structure in XML whereby:

<Route name="MainRoute" ID="123">
  <InnerRoute symbol="stopSign" symbolID="abc"/>
  <InnerRoute symbol="yieldSign" symbolID="def"/>
    <Swale width="5" swaleID="zzz"/>
</Route>

and I wish to represent this as a Tree, thus:
MainRoute
-- stopSign
-- yieldSign
-- 5

The DataSource that I am wishing to create is:

isc.DataSource.create({
ID:"bigroute",
dataURL:"/routes/routeShow.do?type=all",
recordXPath:"//Route",
autoFetchData:false,
fields: [
{type:"text",
required:true,
name:"routeName",
valueXPath:"@name"
},
{type:"text",
required:true,
name:"symbolName",
valueXPath:"/InnerRoute/@symbol"
},
{type:"text",
required:true,
name:"swaleWidth",
valueXPath:"/InnerRoute/Swale/@width"
}
]
});

...and the Tree Grid as:

isc.TreeGrid.create({
ID:"Routes",
dataSource:"bigroute",
loadDataOnDemand:true,
autoFetchData:true,
autoDraw:true,
height:"100%"
})

What do get, however, is just a list of never-ending repeats of nested values of only the route "@name" attribute.

Thank you in advance!

Hi sonny,

Your XML sample doesn't really correspond to a single DataSource - it's actually a series of different types of elements with unrelated sets of properties.

A couple of options:

1. change the XML output so that you have a common set of tagNames and attributes across all record types, following the pattern shown for trees loading XML.

2. if you load this file with loadXML, you could use a DOMGrid to view it.

Interesting. DOMGrid sounds like what I may just need. Thank you; I will try that out!
