System.Xml.XmlException:给定编码中的字符无效。第8271行,第163位

标签: c# xml encoding

我正在编写一个简单的XML解析器,它将传递此XML输出:http://www.cpalead.com/dashboard/reports/campaign_rss.php?id=187000

完整的C#代码是:

    protected void LoadXML()
    {
        XDocument ourBlog = XDocument.Load("http://www.cpalead.com/dashboard/reports/campaign_rss.php?id=187000");
        ourBlog.Declaration.Encoding = "ISO-8859-1";
        XNamespace NameSpace = "http://www.cpalead.com/feeds/campinfo.php";
        var XMLItem = from item in ourBlog.Descendants("item")
                      select new
                      {
                          title = item.Element("title").Value,
                          link = item.Element("link").Value,
                          guid = item.Element("guid").Value,
                          description = item.Element("description").Value,
                          campinfoamount = item.Element(NameSpace + "amount").Value,
                          campinfocampid = item.Element(NameSpace + "campid").Value,
                          campinfocountry = item.Element(NameSpace + "country").Value,
                          campnfotype = item.Element(NameSpace + "type").Value,
                          campinfoepc = item.Element(NameSpace + "epc").Value,
                          campinforatio = item.Element(NameSpace + "ratio").Value
                      };

        foreach (var item in XMLItem)
        {
            offers.InnerHtml += item.title + item.campinforatio + "<br>";
        }

    }

offer是一个div元素。 当我运行此代码时,我得到一个“System.Xml.XmlException:给定编码中的无效字符。行8271,位置163.”错误 如您所见,我还使用ourBlog.Declaration.Encoding =“”设置了编码。 我试过了:

  • ISO-8859-1
  • UTF-8
  • 窗口-1251
  • windows 1252
  • UTF-16

我不知道还有什么可以尝试的。 你有什么建议吗?

好的,我在这里找到了一个有效的解决方案。

这是新代码:

protected void LoadXML()
    {
        var wc = new WebClient();
        using (var sourceStream = wc.OpenRead("http://www.cpalead.com/dashboard/reports/campaign_rss.php?id=187000"))
        {
            using (var reader = new StreamReader(sourceStream))
            {
                XDocument ourBlog = XDocument.Load(reader);
                XNamespace NameSpace = "http://www.cpalead.com/feeds/campinfo.php";
                var XMLItem = from item in ourBlog.Descendants("item")
                              select new
                              {
                                  title = item.Element("title").Value,
                                  link = item.Element("link").Value,
                                  guid = item.Element("guid").Value,
                                  description = XmlConvert.VerifyXmlChars(item.Element("description").Value),
                                  amount = item.Element(NameSpace + "amount").Value,
                                  campid = item.Element(NameSpace + "campid").Value,
                                  country = item.Element(NameSpace + "country").Value,
                                  type = item.Element(NameSpace + "type").Value,
                                  epc = item.Element(NameSpace + "epc").Value,
                                  ratio = item.Element(NameSpace + "ratio").Value
                              };

                foreach (var item in XMLItem)
                {
                    offers.InnerHtml += item.title + " : " + item.description + " : " + item.amount + "<br />"; 
                }
            }
        }
    }

希望这将有助于其他人。

您的XML文件确实无效。它的编码显然是UTF-8。但是第8271行存在问题。

这条线基本上是这样的:

    <description>eMusic δίνει οπαδούς μουσικής της φανταστική συναλλάσσεται για μεγάλη μουσική, κατά μέσο όρο περίπου τα μισά από Amazon ή το iTunes κατάστημα. Έναρξ_</description>

但是在我放下划线的结束标记之前,数据似乎在UTF-8多字节字符的中间被截断。在十六进制中它看起来像这样:

CF 81 CE BE CE 3C 2F 64 65

CF 81 CE BE是希腊字母ρξ,3C 2F 64 65是</de。但剩余的CE启动一个被切断的多字节序列。该值被切断为255个字节!

您需要修复源文件。它无效。在IT中,255字节不是随机长度。可能缺少更多数据。
