Question

尝试读取文件时遇到问题。 XML文件的内容包含无效字符。该字符为'&'。

我尝试通过替换无效字符和try / catch来解决问题，但我还有其他异常，因为该文件正由另一个程序使用。

以下是我的XML示例：

<?xml version="1.0" encoding="ISO-8859-1"?>
<ALABAMAOGANYWHERE file="" LSP="73089617000107" datetime="20170201|094839" records="1">
    <NEWSHIPMENT id="701781" type="OUT&BOUND" dtRequest="20170201|000000">
        <ORIGIN name="Sousas & Sousas LTDA" address="RUA PAUL GROUND , 1415" country="BRASIL" state="PR" city="CURITIBA" cdPostal="81460040"/>  
    </NEWSHIPMENT> 
</ALABAMAOGANYWHERE>

这是我尝试阅读的方式：

    public void lerArquivoXML()
    {

        string[] arquivos = Directory.GetFiles(@"C:\Users\la\Documents\teste");

        foreach (string arq in arquivos)
        {             
            XmlDocument doc = new XmlDocument();
            try
            {
                doc.Load(arq);
            }
            catch (System.Xml.XmlException)
            {
                //replace---------------------------------------------------------------------------
                Replace replace = new Replace();
                replace.ReplaceTextInFile(arq, arq, "&", "");
                doc.Load(arq);
                //end_replace------------------------------------------------------------------------
           }

类替换

class Replace
{

    #region
    public void ReplaceTextInFile(string originalFile, string outputFile, string searchTerm, string replaceTerm)
    {
        string tempLineValue;
        using (FileStream inputStream = File.OpenRead(originalFile))
        {
            using (StreamReader inputReader = new StreamReader(inputStream))
            {
                using (StreamWriter outputWriter = File.AppendText(outputFile))
                {
                    while (null != (tempLineValue = inputReader.ReadLine()))
                    {
                        outputWriter.WriteLine(tempLineValue.Replace(searchTerm, replaceTerm));
                    }                     
                    outputWriter.Close();
                }
            }
        }
    }
    #endregion
}

Answer 1

试试

doc.LoadXml(File.ReadAllText(arq).Replace("&", "&amp;"));

而不是

doc.Load(arq);

在你的try块中

XML用c＃替换无效字符
