CodeGo.net>有什么容易的浪费将XML输出从sharepoint GetListItems()转换为DataTable
作者:互联网
我能够从共享点检索数据
com.sharepoint2.Lists lists = new Lists();
lists.Credentials = new System.Net.NetworkCredential("user", "pwd", "domain");
lists.Url = "http://sharepoint2.company.com/sites/mysite/_vti_bin/Lists.asmx";
XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode ndQueryOptions = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");
XmlNode listitems = lists.GetListItems("MyList", null, ndQuery, ndViewFields, null,ndQueryOptions, null);
我现在拥有一个包含所有数据的巨大XML博客.有没有简单的方法可以将其转换为数据表,所以我将其视为矩阵来遍历每一行?
我尝试过类似的方法,但似乎不起作用:
System.IO.StringReader sr = new System.IO.StringReader(listitems.OuterXml);
XmlTextReader tr = new XmlTextReader(sr);
DataSet ds = new DataSet("resultDataSet");
ds.ReadXml(tr);
解决方法:
嗯,从GetListItems返回的xml与SPListItemCollection.Xml相同.我有一个扩展方法,可以将此XML转换为数据表.
您可以尝试在返回的XML上使用ConvertZRowToRegularXml方法-您将获得DataTable可以理解的XML.
