用新值替换整个 XmlElement

发布于 2024-12-17 04:56:07 字数 1622 浏览 0 评论 0原文

我有下面的代码，我在其中获取 html，然后读取所有 img 和 a 链接。请注意，这是 C# 2.0。

string xml = "<xhtml>" + inputXhtml + "</xhtml>";
XmlDocument node = new XmlDocument();
node.LoadXml(xml);
foreach (XmlElement element in TemplateUtilities.SelectNodes(node, "//html:img[@xlink:href]|//html:a[@xlink:href]"))
{
    bool flag = element.LocalName == "img";
    lStrCompLinkText = "";
    XmlAttributeCollection attributes = element.Attributes;
    XmlAttribute namedItem = (XmlAttribute)attributes.GetNamedItem("href", "http://www.w3.org/1999/xlink");
    string str2 = namedItem.Value;              
    Component currentObject = engine.GetObject(str2) as Component;
    if (flag)
    {
        element.SetAttribute("src", str2);
    }
    else
    {
        foreach (XmlNode xnode in element.ChildNodes)
        {
            lStrCompLinkText = lStrCompLinkText + xnode.OuterXml;
        }   
        string attr = ComponentBase.ComponentHelper.ComponentLinkAttributes(element, engine);       
        string compLink = ComponentBase.ComponentHelper.DisplayPublishedComponentLink(currentObject, lStrCompLinkText, attr, engine, package, pageObject);

        attributes.RemoveNamedItem("href", "http://www.tridion.com/ContentManager/5.0");
        //Here I want to replace whole element with the compLink
    }
    attributes.RemoveNamedItem("href", "http://www.w3.org/1999/xlink");
    attributes.RemoveNamedItem("type", "http://www.w3.org/1999/xlink");
    attributes.RemoveNamedItem("title", "http://www.w3.org/1999/xlink");
}

现在我想用新值 compLink 替换我的元素并添加回输入 HTML

请建议

I have got below code in which I am taking html and then reading all the img and a links. Note this is C# 2.0.

string xml = "<xhtml>" + inputXhtml + "</xhtml>";
XmlDocument node = new XmlDocument();
node.LoadXml(xml);
foreach (XmlElement element in TemplateUtilities.SelectNodes(node, "//html:img[@xlink:href]|//html:a[@xlink:href]"))
{
    bool flag = element.LocalName == "img";
    lStrCompLinkText = "";
    XmlAttributeCollection attributes = element.Attributes;
    XmlAttribute namedItem = (XmlAttribute)attributes.GetNamedItem("href", "http://www.w3.org/1999/xlink");
    string str2 = namedItem.Value;              
    Component currentObject = engine.GetObject(str2) as Component;
    if (flag)
    {
        element.SetAttribute("src", str2);
    }
    else
    {
        foreach (XmlNode xnode in element.ChildNodes)
        {
            lStrCompLinkText = lStrCompLinkText + xnode.OuterXml;
        }   
        string attr = ComponentBase.ComponentHelper.ComponentLinkAttributes(element, engine);       
        string compLink = ComponentBase.ComponentHelper.DisplayPublishedComponentLink(currentObject, lStrCompLinkText, attr, engine, package, pageObject);

        attributes.RemoveNamedItem("href", "http://www.tridion.com/ContentManager/5.0");
        //Here I want to replace whole element with the compLink
    }
    attributes.RemoveNamedItem("href", "http://www.w3.org/1999/xlink");
    attributes.RemoveNamedItem("type", "http://www.w3.org/1999/xlink");
    attributes.RemoveNamedItem("title", "http://www.w3.org/1999/xlink");
}

Now I want to replcace my element with the new value compLink and add back to the input HTML

Please suggest

在您的评论“//此处我想替换”出现的位置执行以下操作。

从 compLink 的内容创建一个 XML 文档（假设它是 XML）。

XmlDocument xmlTemp = new XmlDocument();
xmlTemp.loadXml( compLink );

使用以下代码从其父级中删除原始元素

XmlNode ndParent = element.ParentNode;
ndParent.RemoveChild( element);

导入并将新的 xmlTemp 附加到父级

XmlNode ndImport = ndParent.OwnerDocument.ImportNode( xmlTemp.documentElement, true );
ndParent.AppendChild( ndImport.CloneNode( true ) );

At the spot where your comment "// Here I want to replace" appears do the following.

Create an XML Document from the contentes of compLink (assuming it's XML).

XmlDocument xmlTemp = new XmlDocument();
xmlTemp.loadXml( compLink );

Remove the original element from it's parent with the following code

XmlNode ndParent = element.ParentNode;
ndParent.RemoveChild( element);

Import and append the new xmlTemp to the parent

XmlNode ndImport = ndParent.OwnerDocument.ImportNode( xmlTemp.documentElement, true );
ndParent.AppendChild( ndImport.CloneNode( true ) );

我使用以下逻辑解决了上述问题：

XmlDocument lObjTCDCodeDom = new XmlDocument();
lObjTCDCodeDom.LoadXml("<TCDCode/>");
lObjTCDCodeDom.DocumentElement.InnerText = compLink;
element.ParentNode.ReplaceChild(node.ImportNode(lObjTCDCodeDom.DocumentElement, true), element);

然后进一步编写了 XSLT，它检查并替换它，然后我得到实际更新的 xml。

I solved my above problem using below logic:

XmlDocument lObjTCDCodeDom = new XmlDocument();
lObjTCDCodeDom.LoadXml("<TCDCode/>");
lObjTCDCodeDom.DocumentElement.InnerText = compLink;
element.ParentNode.ReplaceChild(node.ImportNode(lObjTCDCodeDom.DocumentElement, true), element);

and then further wrote the XSLT which check the <TCDCode/> and replaces it and then I get actual updated xml.
