XmlDocument 创新对象时, 产生 xmlns="" 的解决方案

今天做开发时碰到的XmlDocument 创新对象时, 产生 xmlns="" 的,经过分析总结了问题所在,有需要朋友参考一下,可能能帮助你解决这个问题。  

 
1. 读取时,应该添加NameSpace.

 

 代码如下 复制代码
var exclDef = excl.SelectSingleNode(@"ns:worksheet/ns:sheetData", excl.GetNameSpaceManager("ns"));      
 public static XmlNamespaceManager GetNameSpaceManager(this XmlDocument xml, string NameSpace)       
{           
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xml.NameTable);            nsmgr.AddNamespace(NameSpace, xml.DocumentElement.NamespaceURI);            return nsmgr;       
}

2. 如果创建 节点,没有指明 NamespaceURI , 则会生成  xmlns="" , 其原因,参考:

       /post_read.asp?BlogID=2524806&PostID=21711977


     如果 ABC 三级的  NameSpaceURI 分别是  XYY , 那么, 生成的 ABC 的  NameSpaceURI分别是  AB空, C 不会生成 NameSpaceURI , 因为, C和其父项具有相同的 NameSpaceURI .


     所以在创建 节点时, 为了不出现 NameSpaceURI , 请保持和节点父项相同的 NameSpaceURI  .

                    var si = e.OwnerDocument.CreateElement("si", e.NamespaceURI);                    e.AppendChild(si);
     另外, 创新 属性时, 不要指定 NameSpaceURI , 即 生成的 Xml 就没有特定的 NameSpaceURI .

                    var r = excl.CreateAttribute("r");

Implementing Machine Learning Algorithms in C++: Common Challenges and Solutions Implementing Machine Learning Algorithms in C++: Common Challenges and Solutions Jun 03, 2024 pm 01:25 PM

Common challenges faced by machine learning algorithms in C++ include memory management, multi-threading, performance optimization, and maintainability. Solutions include using smart pointers, modern threading libraries, SIMD instructions and third-party libraries, as well as following coding style guidelines and using automation tools. Practical cases show how to use the Eigen library to implement linear regression algorithms, effectively manage memory and use high-performance matrix operations.

Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent Apr 07, 2024 am 09:10 AM

On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A
