特殊字符的XDocument [英] Special characters with XDocument

问题描述

我试图读取一个文件（不是XML，但结构类似），但我得到这个异​​常：

I'm trying to read a file (not a XML, but the structure is similar), but i'm getting this Exception:

'┴', hexadecimal value 0x15, is an invalid character. Line 8, position 7.

和文件有很多这样的符号，我不能取代，因为我不能修改文件的内容，我的目的......

and the file have a lot of this symbols, that I can't replace because I can't modify the content of the file for my purposes...

这是代码：

try
{
    XDocument doc = new XDocument(new XDeclaration("1.0", "utf-16", "yes"));
    doc = XDocument.Load(arquivo);
}
catch (Exception e)
{
    MessageBox.Show(e.Message.ToString());
}

这就是该文件的某些部分：

and that's some part of the file:

<Codepage>UTF16</Codepage>
<Segment>0000016125
    <Control>0003┴300000┴English(U.S.)PORTUGUESE┴┴bla.000┴webgui\messages\xsl\en\blabla\blabla.xlf
    </Control>
    <Source>To blablablah the   firewall to blablablah local IP address.    </Source>
    <Target>Para blablablah a uma blablablah local específico.  </Target>
</Segment>

请注意：该文件没有编码XML声明

Note: The file don't have the encode xml declaration.

推荐答案

此XML是非常糟糕;

This XML is pretty bad;

1. 您有<段> 0000016125 在那里它，而不是技术上非法的（这是一个文本节点），就是那种奇


2. 您<。 code><控制> 元素包含无效字符没有一个XML CDATA 部分

1. You have <Segment>0000016125 in there which, while not technically illegal (it is a Text node), is just kind of odd.
2. Your <Control> element contains invalid characters without an XML CDATA section

您可以手动正常化XML或通过字符串处理，正则表达式或，或类似的东西做它在C＃。

You can manually normalize the XML or do it in C# via string manipulation, or RegEx, or something similar.

在您简单的例子，只有<控制> 元素具有无效字符;因此它是比较简单的解决它，并添加使用与string.replace（）的方法，使一个 CDATA 部分它看起来像这样：

In your simple example, only the <Control> element has invalid characters; therefore it is relatively simple to fix it and add a CDATA section using the string.Replace() method, to make it look like this:

<Control><![CDATA[0003┴300000┴English(U.S.)PORTUGUESE┴┴bla.000┴webgui\messages\xsl\en\blabla\blabla.xlf]]></Control>

然后就可以良好的XML加载到你的的XDocument 使用 XDocument.Parse（字符串XML）：

string badXml = @"
    <temproot>
        <Codepage>UTF16</Codepage>
        <Segment>0000016125
            <Control>0003┴300000┴English(U.S.)PORTUGUESE┴┴bla.000┴webgui\messages\xsl\en\blabla\blabla.xlf</Control>
            <Source>To blablablah the   firewall to blablablah local IP address.    </Source>
            <Target>Para blablablah a uma blablablah local específico.  </Target>
        </Segment>
    </temproot>";

// assuming only <control> element has the invalid characters
string goodXml = badXml
    .Replace("<Control>", "<Control><![CDATA[")
    .Replace("</Control>", "]]></Control>");

XDocument xDoc = XDocument.Parse(goodXml);
xDoc.Declaration = new XDeclaration("1.0", "utf-16", "yes");

// do stuff with xDoc
