Replace \Update xmlNode，其中包含XML文档中提供的值 [英] Replace\Update the xmlNode with supplied value in XML document

问题描述

在XML文档中，我们根据xpath搜索xmlNodes，然后我们想要用提供的值完全替换  xmlNodes。

示例

OracleXmlType具有以下数据，Xpath设置为"/ RESUME / NAME"



<？xml version =" 1.0"？>

< RESUME>

   < span style ="color：＃3333ff">  < NAME> Name0< / NAME>

    < NAME> Name1< / NAME>

    < EXPERIENCE>

   &NBSP;&NBSP;&NBSP; < YEARS> 0< / YEARS>

    < / EXPERIENCE>

< / RESUME>

值我们想要替换为以下提供的字符串

< RESUME>

    < NAME> Name0< / NAME>

    < NAME> Name1< / NAME>

< / RESUME>

预期结果是

~~~~~~~~~~~~~~~

<？xml version =" ; 1.0"？>

< RESUME>

    < RESUME>

        < NAME> Name0< / NAME>

        < NAME> Name1< / NAME>

    < / RESUME>

    < RESUME>

        &NBSP; < NAME> Name0< / NAME>

         < NAME> Name1< / NAME>

     < / RESUME>

    < EXPERIENCE>

   &NBSP;&NBSP;&NBSP; < YEARS> 0< / YEARS>

    < / EXPERIENCE>

< / RESUME>

请告诉我实现上述目标的有效方法使用.NET XML相关APIS的功能

解决方案

以下是我用来查找xmlNodes的代码 取决于xpathExpr

但我不知道如何用提供的值替换整个xmlNode，尤其是当它具有嵌套的XML节点时，如

< RESUME>

    < NAME> Name0< / NAME>

    < NAME> Name1< / NAME>

< / RESUME>

static internal void Update（XmlDocument xmlDoc，string xpathExpr，string val）

    {

      XmlNodeList xmlNodes = null;

      xmlNodes = xmlDoc.SelectNodes（xpathExpr）;

     

      if（xmlNodes！= null&& xmlNodes.Count> 0）

      {

        foreach（xmlNode中的xmlNode xmlNode）

        {

         // TODO： 

          //如何替换xmlNode 完全具有提供的价值？

        }
      }
    }

In XML document we search the xmlNodes depending on xpath and then we want to replace the xmlNodes completely with the supplied value.

for Example

OracleXmlType has the below data and Xpath is set to "/RESUME/NAME"

<?xml version="1.0"?>
<RESUME>
    <NAME>Name0</NAME>
    <NAME>Name1</NAME>
    <EXPERIENCE>
       <YEARS>0</YEARS>
    </EXPERIENCE>
</RESUME>

the value we want to replace as below which is supplied as string

<RESUME>
    <NAME>Name0</NAME>
    <NAME>Name1</NAME>
</RESUME>

the expected result is

~~~~~~~~~~~~~~~

<?xml version="1.0"?>
<RESUME>
   <RESUME>
        <NAME>Name0</NAME>
        <NAME>Name1</NAME>
    </RESUME>
    <RESUME>
         <NAME>Name0</NAME>
         <NAME>Name1</NAME>
     </RESUME>
    <EXPERIENCE>
       <YEARS>0</YEARS>
    </EXPERIENCE>
</RESUME>

please tell me the efficient way to achieve the above functionality using the .NET XML related APIS

解决方案

Below is the code i used to find the xmlNodes  depending on xpathExpr

But I am not sure how to replace the whole xmlNode with supplied value especially when it has the nested XML nodes like

<RESUME>
    <NAME>Name0</NAME>
    <NAME>Name1</NAME>
</RESUME>

static internal void Update(XmlDocument xmlDoc, string xpathExpr, string val)
    {
      XmlNodeList xmlNodes = null;
      xmlNodes = xmlDoc.SelectNodes(xpathExpr);
     
      if (xmlNodes != null && xmlNodes.Count > 0)
      {
        foreach (XmlNode xmlNode in xmlNodes)
        {

         //TODO : 

          //how to replace the xmlNode  completely with provided value ?
        }
      }
    }
