添加节点，并使用C＃/ LINQ的中的XML元素 [英] Add node and elements in xml using C#/Linq

问题描述

我有这样一个XML文件，

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT;根和GT;
  ＆LT; FeaturedProductCategories＆GT;
    ＆LT; FeaturedProductCategory＆GT;
      ＆LT;＆特色产品GT;
        ＆LT; FeaturedProduct＆GT;
          ＆LT; ContentSelector datavalue_idtype =内容：智能表datavalue_displayvalue =«智能表：49»＆GT; 49 LT; / ContentSelector＆GT;
        ＆LT; / FeaturedProduct＆GT;
      ＆LT; /＆特色产品GT;
    ＆LT; / FeaturedProductCategory＆GT;
  ＆LT; / FeaturedProductCategories＆GT;
＆LT; /根＆GT;
 

我想修改它类似下面，

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT;根和GT;
  ＆LT;标题＆GT;首页广告和LT; /标题＆GT;
  ＆LT; FeaturedProductCategories＆GT;
    ＆LT; FeaturedProductCategory＆GT;
      ＆LT;＆特色产品GT;
        ＆LT; FeaturedProduct＆GT;
          ＆LT;产品＆GT;
            ＆LT;产品与GT;
              ＆LT; ProductTitle＆GT;产品与LT; / ProductTitle＆GT;
              ＆所述; ProductDate＆GT; 2012年3月8日11：57：25℃/ ProductDate＆GT;
              ＆LT; ProductImage＆GT;
                ＆所述; IMG SRC =ex1.jpg/＆GT;
              ＆LT; / ProductImage＆GT;
              ＆LT; ProductThumbnailImage＆GT;
                ＆所述; IMG SRC =ex2.jpg/＆GT;
              ＆LT; / ProductThumbnailImage＆GT;
              ＆LT; ProductCaption＆GT;产品＆字幕LT; / ProductCaption＆GT;
              ＆LT; ProductImage＆GT;
                ＆所述; IMG SRC =ex3.jpg/＆GT;
              ＆LT; / ProductImage＆GT;
              ＆LT; ProductThumbnailImage＆GT;
                ＆所述; IMG SRC =ex4.jpg/＆GT;
              ＆LT; / ProductThumbnailImage＆GT;
              ＆LT; ProductCaption＆GT;产品＆字幕LT; / ProductCaption＆GT;
            ＆LT; /产品与GT;
          ＆LT; /产品＆GT;
        ＆LT; / FeaturedProduct＆GT;
      ＆LT; /＆特色产品GT;
    ＆LT; / FeaturedProductCategory＆GT;
  ＆LT; / FeaturedProductCategories＆GT;
＆LT; /根＆GT;
 

所有的新节点和值是通过一个C＃功能被添加。让我们假定这些新值静态值了。

另外，节点FeaturedProduct不是唯一的一个。有很多在该名称的节点。我想修改所有FeaturedProduct节点。

解决方案

这不使用LINQ准确，但它会成为你的目的。

  XDOC XmlDocument的=新的XmlDocument（）;
        xDoc.Load（filename.xml中）;        的foreach（XmlNode的xNode在xDoc.SelectNodes（// FeaturedProduct））
        {
            的XmlElement为newElement = xDoc.CreateElement（newElementName）;
            XmlAttribute newAttribute = xDoc.CreateAttribute（为AttributeName）;
            newAttribute.Value =的AttributeValue;
            newElement.Attributes.Append（newAttribute）;            xNode.AppendChild（为newElement）;
            xNode.InnerText =myInnerText;
        }
 

此外，本文档是用于XPath <一个非常方便的参考/ p>

I have an xml file like this,

<?xml version="1.0" encoding="utf-8" ?>
<root>  
  <FeaturedProductCategories>
    <FeaturedProductCategory>
      <FeaturedProducts>
        <FeaturedProduct>
          <ContentSelector datavalue_idtype="content:smartform" datavalue_displayvalue="«Smart Form:49»">49</ContentSelector>
        </FeaturedProduct>
      </FeaturedProducts>
    </FeaturedProductCategory>
  </FeaturedProductCategories>
</root>

I want to modify it like the one below,

<?xml version="1.0" encoding="utf-8" ?>
<root>
  <Title>HomePage</Title>
  <FeaturedProductCategories>
    <FeaturedProductCategory>
      <FeaturedProducts>
        <FeaturedProduct>
          <Products>
            <Product>
              <ProductTitle>Product</ProductTitle>
              <ProductDate>03-08-2012 11:57:25</ProductDate>
              <ProductImage>
                <img src="ex1.jpg" />
              </ProductImage>
              <ProductThumbnailImage>
                <img src="ex2.jpg" />
              </ProductThumbnailImage>
              <ProductCaption>Product Caption</ProductCaption>
              <ProductImage>
                <img src="ex3.jpg" />
              </ProductImage>
              <ProductThumbnailImage>
                <img src="ex4.jpg" />
              </ProductThumbnailImage>
              <ProductCaption>Product Caption</ProductCaption>
            </Product>
          </Products>
        </FeaturedProduct>
      </FeaturedProducts>
    </FeaturedProductCategory>
  </FeaturedProductCategories>
</root>

All the new nodes and values are to be added through a C# function. Let us assume these new values as static values for now.

Also the node "FeaturedProduct" is not only one. There are a lot of nodes in that name. I want to modify all the "FeaturedProduct" nodes.

解决方案

This doesn't use linq exactly, but It will serve your purpose

        XmlDocument xDoc = new XmlDocument();
        xDoc.Load("filename.xml");

        foreach (XmlNode xNode in xDoc.SelectNodes("//FeaturedProduct"))
        {
            XmlElement newElement = xDoc.CreateElement("newElementName");
            XmlAttribute newAttribute = xDoc.CreateAttribute("AttributeName");
            newAttribute.Value = "attributeValue";
            newElement.Attributes.Append(newAttribute);

            xNode.AppendChild(newElement);
            xNode.InnerText = "myInnerText";
        }

Also, This Documentation is a very handy reference for Xpath
