问题描述
我目前正在使用包含 webPartDescription (XML)
集合的文件上传控件导入Webparts。<wrapper>
<webParts>
<webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
<MetaData>
<type src="~/Web/Controls/Test/TestHeaderList.ascx" />
<importErrorMessage>Cannot import this Web Part.</importErrorMessage>
</MetaData>
<data>
<properties>
<property name="UserCancelled" type="bool">False</property>
<property name="AllowedRoles" type="string" null="true" />
<property name="SourceFileName" type="bool">False</property>
<property name="ViewFilterExpression" type="string" />
<property name="UserCreated" type="bool">False</property>
<property name="HideExportButtons" type="bool">False</property>
<property name="RecordCount" type="bool">False</property>

<property name="DeltaCount" type="bool">False</property>
<property name="OrdersHeaderBatchNo" type="bool">False</property>
<property name="DateCancelled" type="bool">False</property>
<property name="ResponseDescription" type="bool">False</property>
<property name="RunDate" type="bool">False</property>
<property name="DateCreated" type="bool">False</property>
<property name="ResponseCode" type="bool">False</property>
</properties>
<genericWebPartProperties>
<property name="Width" type="unit" />
<property name="Description" type="string" />
<property name="AllowEdit" type="bool">True</property>
<property name="ChromeType" type="chrometype">Default</property>

<property name="ExportMode" type="exportmode">NonSensitiveData</property>
</genericWebPartProperties>
</data>
</webPart>
</webParts>
</wrapper>
我想过滤并获取属性名称为“ Title”的“ genericWebPartProperties”中的property元素的值 例如:订单标题列表(在xml上方)
我是linq和xml的新手。我尝试了几种解决方案,但收到了空值
我后面的代码如下:
//Uploded xml containing multible webparts wraped under <wrapepr> root tag.
XDocument UploadedXmlWebparts = XDocument.Load(e.UploadedFile.FileContent);
// fetching individual webpart xml and storing in a Xelement Collection
var WebpartCollection = UploadedXmlWebparts.Root.Elements();
List<ClsImportWp> WebPartDescriptionList = new List<ClsImportWp>();
foreach (XElement webPart in WebpartCollection)
{
var TitleName = // Get the title tag value here
}
解决方法
在字典中使用xml linq:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication166
{
class Program
{
const string FILENAME = @"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement genericWebPartProperties = doc.Descendants().Where(x => x.Name.LocalName == "genericWebPartProperties").FirstOrDefault();
XNamespace ns = genericWebPartProperties.GetDefaultNamespace();
Dictionary<string,string> dict = genericWebPartProperties.Elements(ns + "property")
.GroupBy(x => (string)x.Attribute("name"),y => (string)y)
.ToDictionary(x => x.Key,y => y.FirstOrDefault());
}
}
}
