# YUI Library Examples: DataTable Control: XML Data with XPath

# DataTable Control: XML Data with XPath

This DataTable is populated with XML data where the schema is defined using XPath-syntax locators. Please note that namespace support is not implemented at this time.

View example in new window.

When working with XML data, use the DataSource's `useXPath` property to enable XPath syntax in your locator strings.

## Sample Code for this Example

Data:

<myroot rootatt='5'> <top>topvalue</top> <second nested='nestedsecond' /> <allitems> <livehere> <item type='foo'> <name type='nametype0'>Abc</name> <rank>0</rank> <subitem> <name type='subnametype0'>subABC</name> <age>10</age> </subitem> </item> <item type='bar'> <name type='nametype1'>Def</name> <rank>1</rank> <subitem> <name type='subnametype1'>subDEF</name> <age>11</age> </subitem> </item> <item type='bat'> <name type='nametype2'>Ghi</name> <rank>2</rank> <subitem> <name type='subnametype2'>subGHI</name> <age>12</age> </subitem> </item> </livehere> </allitems> </myroot>

CSS:

/* No custom CSS. */

Markup:

<div id="xpath"></div>

JavaScript:

YAHOO.util.Event.addListener(window, "load", function() { YAHOO.example.XPath = function() { var myColumnDefs = [ {key:"type"}, {key:"rank"}, {key:"subnameatt"}, {key:"age"}, {key:"name"} ]; var myDataSource = new YAHOO.util.DataSource("assets/php/xml_proxy.php"); myDataSource.responseType = YAHOO.util.DataSource.TYPE_XML; myDataSource.useXPath = true; myDataSource.responseSchema = { metaFields: {rootatt:"/myroot/@rootatt", topnode:"//top", nestedatt:"//second/@nested"}, resultNode: "item", fields: [{key:"type", locator:"@type"}, {key:"rank", parser:"number"}, "name", {key:"subnameatt", locator:"subitem/name/@type"}, {key:"age", locator:"subitem/age", parser:"number"}] }; var myDataTable = new YAHOO.widget.DataTable("xpath", myColumnDefs, myDataSource); return { oDS: myDataSource, oDT: myDataTable }; }(); });
