我有一个客户端API，它以下列格式向我发送XML。我必须更改几个值并将相同的XML发送到我的客户端的另一个API。什么是最好的方法。我们目前正在使用SQL Server 2014和C＃。

我遵循以下方法。我用一些变量替换了我的XML中的所有值字段，用管道（|）符号分隔它们。请在下面找到替换的那个。

之后在SQL Server中我将它们替换为所需的值并将该XML转发给我的客户端。
set @Nxml = replace(@Nxml, '|JAct_M|','Add')
set @Nxml = replace(@Nxml, '|JID_M|',@reqmt_id)
set @Nxml = replace(@Nxml, '|JType_M|','P')
这是最好的方法还是有其他简单的方法。 提前谢谢。

最好的方法（仅在您应该获取xml，修改它然后通过修改的xml传递）将使用XPathNavigator（更改JobAction的示例）：
public static string UpdateJobAction(string inputXml)
{
var xmlDocument = new XmlDocument();
xmlDocument.LoadXml(inputXml);
var xpnavigator = xmlDocument.CreateNavigator();
foreach (XPathNavigator xpn in xpnavigator.Select("//JobPositionPostings/JobPositionPosting/JobAction"))
{
var value = xpn.Value; // to obtain the JobAction value
xpn.SetValue("Add");
}
return xpnavigator.OuterXml;
}

在这种情况下，您正在修改许多元素。所以我建议使用序列化。以下是一个开始。我读取文件并反序列化，然后写出相同的结果。我建议您继续使用原始数据，并将输入和输出进行比较。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
const string INPUT_FILENAME = @"c:\temp\test1.xml";
const string OUTPUT_FILENAME = @"c:\temp\test2.xml";
static void Main(string[] args)
{
JobPositionPostings postings = Load(INPUT_FILENAME);
// modify posting here
Save(OUTPUT_FILENAME, postings);
}
static JobPositionPostings Load(string filename)
{
StreamReader reader = new StreamReader(INPUT_FILENAME);
XmlSerializer serializer = new XmlSerializer(typeof(JobPositionPostings));
JobPositionPostings postings = (JobPositionPostings)serializer.Deserialize(reader);
return postings;
}
static void Save(string filename, JobPositionPostings postings)
{
XmlSerializer serializer = new XmlSerializer(typeof(JobPositionPostings));
StreamWriter writer = new StreamWriter(filename);
serializer.Serialize(writer, postings);
}
}
[XmlRoot("JobPositionPostings")]
public class JobPositionPostings
{
[XmlElement("JobPositionPosting")]
public List<JobPositionPosting> jobPositionPostings { get; set; }
}
[XmlRoot("JobPositionPosting")]
public class JobPositionPosting
{
[XmlElement("JobAction")]
public string JobAction { get; set; }
[XmlElement("JobType")]
public string jobType { get; set; }
[XmlElement("JobPositionPostingID")]
public int jobPositionPostingID { get; set; }
[XmlElement("HiringOrg")]
public HiringOrg hiringOrg { get; set; }
[XmlElement("JobDisplayOptions")]
public JobDisplayOptions jobDisplayOptions { get; set; }
}
[XmlRoot("HiringOrg")]
public class HiringOrg
{
[XmlElement("HiringOrgName")]
public string hiringOrgName { get; set; }
[XmlElement("Industry")]
public Industry industry { get; set; }
[XmlElement("Contact")]
public Contact contact { get; set; }
}
[XmlRoot("Industry")]
public class Industry
{
[XmlElement("SummaryText")]
public string summaryText { get; set; }
[XmlElement("Contact")]
public string contact { get; set; }
}
[XmlRoot("Contact")]
public class Contact
{
[XmlElement("PersonName")]
public PersonName personName { get; set; }
}
[XmlRoot("PersonName")]
public class PersonName
{
[XmlElement("FormattedName")]
public string formattedName { get; set; }
}
[XmlRoot("JobDisplayOptions")]
public class JobDisplayOptions
{
[XmlElement("MicrositeName")]
public string micrositeName { get; set; }
[XmlElement("TemplateName")]
public string templateName { get; set; }
}
}

要使用SQL-Server修改XML，您可以使用XML数据类型的函数.modify()。首先，您必须将XML转换/转换为真实 XML类型。
不要在字符串级别处理XML！
检查一下（为简洁起见缩短）：
DECLARE @xml XML=
N'<?xml version="1.0"?>
<JobPositionPostings>
<JobPositionPosting>
<JobAction>ADD</JobAction>
<JobType>p</JobType>
<JobPositionPostingID>27</JobPositionPostingID>
<HiringOrg>
<HiringOrgName>Company Name</HiringOrgName>
<Industry>
<SummaryText>Brief description of the hiring organization</SummaryText>
</Industry>
<Contact>
<PersonName>
<FormattedName>Name of the Hiring Contact</FormattedName>
</PersonName>
</Contact>
</HiringOrg>
<JobDisplayOptions>
<MicrositeName>Client Microsite Name</MicrositeName>
<TemplateName>Client Template Name</TemplateName>
</JobDisplayOptions>
<!-- More nodes -->
</JobPositionPosting>
<JobFeedResponseEmail>Tech person''s E-mail for receiving Feed Status</JobFeedResponseEmail>
</JobPositionPostings>';
- 使用硬编码新值替换一个特定现有元素的值
SET @xml.modify(N'replace value of (/JobPositionPostings/JobPositionPosting/JobAction/text())[1] with "SomeNewValue"');
- 您可以使用sql:variable("@SomeVariable")或sql:column("SomeColumn")动态获取值
DECLARE @NewJobType NVARCHAR(100)='NewType';
SET @xml.modify(N'replace value of (/JobPositionPostings/JobPositionPosting/JobType/text())[1] with sql:variable("@NewJobType")');
- 在特定位置引入新元素
SET @xml.modify(N'insert <SomeNewElement>test</SomeNewElement> after (/JobPositionPostings/JobPositionPosting/JobType)[1]');
- 删除一个（完整）元素
SET @xml.modify(N'delete (/JobPositionPostings/JobPositionPosting/HiringOrg)[1]');
- 检查修改后的结果
SELECT @xml;
<JobPositionPostings>
<JobPositionPosting>
<JobAction>SomeNewValue</JobAction>
<JobType>NewType</JobType>
<SomeNewElement>test</SomeNewElement>
<JobPositionPostingID>27</JobPositionPostingID>
<JobDisplayOptions>
<MicrositeName>Client Microsite Name</MicrositeName>
<TemplateName>Client Template Name</TemplateName>
</JobDisplayOptions>
<!-- More nodes -->
</JobPositionPosting>
<JobFeedResponseEmail>Tech person's E-mail for receiving Feed Status</JobFeedResponseEmail>
</JobPositionPostings>
