Question

我收到了这个错误，到目前为止我发现的只是“移除空间”，但没有空间。这是一个我发现的脚本，它将从任何文件格式中获取一个简历并提取数据（解析它），以便将它放入SQL数据库......还没有那么远

ASP.net代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ResumeParser.aspx.cs"       Inherits="CsharpSamCodeResumeParser_USAResume" Debug="true" ValidateRequest="false" %>

            </tr>

    <table>

Answer 1

我怀疑因为你是通过字符串连接创建xml文档，所以你无意中从一个变量中添加了格式错误的xml。也许其中一个有一个小于号，这导致Xml解析器炸弹。您应该尝试通过DOM创建文档，或者使用CDATA部分来创建可配置值。

string url = TxtUrl.Text;        
string userkey = (string)ConfigurationSettings.AppSettings["userKey"];
string version = (string)ConfigurationSettings.AppSettings["Version"];
string countryKey=(string)ConfigurationSettings.AppSettings["CountryKey"];    

strRequest.Append("<url>" + url + "</url>");
strRequest.Append("<key>" + userkey + "</key>");
strRequest.Append("<version>" + version + "</version>");
strRequest.Append("<countryKey>" + countryKey + "</countryKey>");

我会尝试将strRequest StringBuilder写入文件，然后在xml编辑器中打开它，并找出问题所在。

Answer 2

你在这里有相互矛盾的陈述：

strRequest.Append("<?xml version='1.0' encoding='utf-8'?>");

VS

byte[] byteArray = Encoding.ASCII.GetBytes(strRequest.ToString());

你可能搞乱编码并最终得到不需要的字符。

您应该Encoding.ASCII替换Encoding.UTF8。

获取System.Xml.XmlException：名称不能以''字符，十六进制值0x20开头。第42行，第36位
