如何使用C＃比较两个xml注册表备份 [英] how to compare between two xml registry backup using C#

问题描述

 使用 Microsoft.XmlDiffPatch; 
 System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create（  D：\\ diff.xml）; 
 
  //   XmlDiffOptions枚举中有许多可用选项 
 XmlDiff diff =  new  XmlDiff（XmlDiffOptions.IgnoreChildOrder | XmlDiffOptions.IgnoreComments | XmlDiffOptions.IgnoreWhitespace | XmlDiffOptions.IgnoreXmlDecl | XmlDiffOptions.IgnorePI | XmlDiffOptions.IgnoreNamespaces | XmlDiffOptions.IgnorePrefixes | XmlDiffOptions.IgnoreDtd）; 
 
 
 diff.Compare（ @  D：\\ registrybackup。 xml， @  D：\\registrybackupthef.xml， true ，writer）; 

我从两个pc 
获取2 xml备份注册表，当我比较它们时
i有错误
 
 
 System.Xml.XmlException未处理
 Message ='。'，十六进制值0x00，是无效字符。第8行，第39位。

谢谢。

解决方案

好吧，看看XML标准。代码点0的字符不被视为XML中的有效字符。



因为您没有显示如何获取XML文件而没有显示任何XML样品，这就是全部。您问题中的其他所有内容都无关紧要：解析代码可能正确，但不是XML文件。

抱歉我忘了写样本xml备份注册表

using Microsoft.XmlDiffPatch;
            System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create("D:\\diff.xml");

            // There are a number of available options in the XmlDiffOptions enum
            XmlDiff diff = new XmlDiff(XmlDiffOptions.IgnoreChildOrder | XmlDiffOptions.IgnoreComments | XmlDiffOptions.IgnoreWhitespace | XmlDiffOptions.IgnoreXmlDecl | XmlDiffOptions.IgnorePI | XmlDiffOptions.IgnoreNamespaces | XmlDiffOptions.IgnorePrefixes | XmlDiffOptions.IgnoreDtd);
             

            diff.Compare(@"D:\\registrybackup.xml", @"D:\\registrybackupthef.xml", true, writer);

i take 2 xml backup registry from two pc
when i  compare between them
i have that error

解决方案

Well, look at the XML standard. The character with the code point 0 is not considered as a valid character in XML.

As you did not show how you obtained the XML file and did not show any XML sample, that''s all. Everything else in your question is irrelevant: the parsing code may be correct, but not the XML file.

sorry i forget to write sample xml backup registry
