[ciach wszystko bo moje]
a jednak znalazlem...
polecam kopalnie wiedzy na CodeProject (www.codeproject.com)
Fragment XML:
<?xml version="1.0" standalone="yes"?>
<Root>
<Region>
<RegionID>1</RegionID>
<RegionDescription>Reeeeeaalllly Far East!</RegionDescription>
</Region>
<Region>
<RegionID>2</RegionID>
.....
wyszukany fragment kodu przeszukujacego (nie jest to bezposrednio XPath, ale
tez sie nadaje) :
---------------------------------------------------------
using System;
using System.Data;
using System.Xml;
namespace Wrox.ProDotNet.Chapter10.XPath_XmlDataDocument
{
class ClassMain
{
static void Main(string[] args)
{
DataSet RegionDS = new DataSet();
DataRow RegionRow;
RegionDS.ReadXmlSchema( " Region_More.XSD" );
XmlDataDocument DataDoc = new XmlDataDocument( RegionDS );
DataDoc.Load( " Region_More.XML" );
// Now we'll select all of the regions that have
// a RegionID > 2.
XmlNodeList NodeMatches =
DataDoc.SelectNodes("//Root//Region[@RegionID>2]");
Console.WriteLine( "------------------------" );
foreach ( XmlNode tmpNode in NodeMatches )
{
// pull up corresponding row in the DS.
RegionRow = DataDoc.GetRowFromElement( (XmlElement)tmpNode );
Console.WriteLine(RegionRow["RegionDescription"]);
}
}
}
}
Pozdrawiam
