You may have noticed that in ExtJS 3.4 that you can’t use namespaces in your Ext.dataXmlReader.
So a xml reader defined like the example below does not work with the following xml:
1
2
3
4
5
6
7
| var Employee = Ext.data.Record.create([
{name: 'name', mapping: 'gml:name'},
{name: 'gml:occupation'}
]);
var myReader = new Ext.data.XmlReader({
record: "gml|row" // The repeated element with gml namespace (gml:row)
}, Employee); |
The above should consume an xml file defined like so:
1
2
3
4
5
6
7
8
9
10
11
| <?xml version="1.0" encoding="UTF-8"?>
<dataset>
<gml:row>
<gml:name>Bill</gml:name>
<gml:occupation>Gardener</gml:occupation>
</gml:row>
<gml:row>
<gml:name>Ben</gml:name>
<gml:occupation>Horticulturalist</gml:occupation>
</gml:row>
</dataset> |
But it doesn’t…
That is because ExtJS 3.4 DomQuery does not support namespaces. They fixed this problem in 4 but those of you still using the 3.4 framework might find my hotfix useful. If just interested in using the files themselves I have attached them at the bottom of this post. Here are the changes I made:
Changed:
1

3
| // tagTokenRe = /^(#)?([\w\-\*]+)/, // Removed
tagTokenRe = /^(#)?([\w\-\*\|\\]+)/, // Added: allows vertical bars to be included
supportsColonNsSeparator, // Added |
