我有一个简单的xmlfile,它放在树视图中
<bookstore xmlns="generic">
<book genre="Book" >`
<title>Book of Benjamin Franklin</title>
<author>
<first-name>Benson</first-name>
<last-name>Frank</last-name>
</author>
<price>89.88</price>
</book>
<book genre="autobiography">
<title>The Autobiography of Benjamin Franklin</title>
<author>
<first-name>Ben</first-name>
<middlename />
<last-name>Franklin</last-name>
</author>
<price>89.88</price>
</book>
<book genre="novel" >
<title>The Confidence Man</title>
<author>
<first-name>John</first-name>
<last-name>Melville</last-name>
</author>
<price>11.99</price>
</book>
</bookstore>
我想替换(第二个元素)
<book genre="autobiography" >
<title>The Autobiography of Benjamin Franklin</title>
<author>
<first-name>Ben</first-name>
<middlename />
<last-name>Franklin</last-name>
</author>
<price>89.88</price>
</book>
使用另一个元素(已编辑并且我已将部分编辑为字符串)
<book genre="autobiography">
<title>The Autobiography of Benjamin Franklin</title>
<author>
<first-name>Ben</first-name>
<last-name>Franklin</last-name>
</author>
<price>89.88</price>
</book>
我使用的代码在这里
XElement XmlTree = XElement.Parse(text);//text contain edited portion
XmlElement XMLE = (XmlElement)TreeV.SelectedItem;
XmlDocument xdoc = new XmlDocument();
xdoc.Load(scd_file);
XmlDocumentFragment xfrag = xdoc.CreateDocumentFragment();
xfrag.InnerXml = text;
XmlDocumentFragment xfrag1 = xdoc.CreateDocumentFragment();
xfrag1.InnerXml = XMLE.OuterXml;
xdoc.ReplaceChild(xfrag, xfrag1);
但它显示错误(xfrag1不是xdoc的节点) 请帮我解决这个问题。
答案 0 :(得分:0)
XmlElement XMLE = (XmlElement)TreeV.SelectedItem;// selection from treeview(TreeV) that we want to edit (2nd element)
XmlDocument XD = new XmlDocument();
XD.LoadXml(text);// text is edited part save as a string
XmlNode root=XD.DocumentElement;
XmlDocument xml = XMLE.ParentNode.OwnerDocument;
XmlNode import= xml.ImportNode(root, true);
XMLE.ParentNode.ReplaceChild(import, XMLE);
xml.Save(scd_file); //scd_file path
