問題描述

我需要解析 Html 代碼.更具體地說，解析所有表中每一行的每個單元格.每行代表一個對象，每個單元格代表不同的屬性.我想解析這些以便能夠編寫一個包含每個數據的 XML 文件(沒有無用的 HTML 代碼).我已經成功地解析了 HTML 文件中的每一列，但現在我不知道將其寫入 XML 文件的選項是什么.我很困惑.

I need to parse Html code. More specifically, parse each cell of every rows in all tables. Each row represent a single object and each cell represent different properties. I want to parse these to be able to write an XML file with every data inside (without the useless HTML code). I have successfully been able to parse each column from the HTML file but now I don't know what my options are for writing this to an XML file. I am baffled.

HTML:

<tr><tr> 
<td class="statBox" style="border-width:0px 1px 1px 0px; background-color: #FFFFFF"> 
    1
</td> 
    <td class="statBox" style="border-width:0px 1px 1px 0px; background-color: #FFFFFF" align="left"> 
        <a href="/ice/player.htm?id=8471675">Sidney Crosby</a>

看了一圈MSDN，終于找到了解決自己問題的實現方案:

After looking around MSDN, I finally found an implementation solution to my problem:

    using System;
    using HtmlAgilityPack;
    using System.Xml;

    namespace HockeyStats
    {
        class StatsParser
        {
            private string htmlCode;
            private static string fileName = "[" + DateTime.Now.ToShortDateString() + " NHL Stats].xml";

            public StatsParser(string htmlCode)
            {
                this.htmlCode = htmlCode;

                this.ParseHtml();
            }

            public void ParseHtml()
            {

                HtmlDocument doc = new HtmlDocument();
                doc.LoadHtml(htmlCode);
                XmlWriter writer = null;

                try
                {
                    // Create an XmlWriterSettings object with the correct options. 
                    XmlWriterSettings settings = new XmlWriterSettings();
                    settings.Indent = true;
                    settings.IndentChars = ("  ");
                    settings.OmitXmlDeclaration = false;

                    // Create the XmlWriter object and write some content.
                    writer = XmlWriter.Create(@"...."+fileName, settings);
                    writer.WriteStartElement("Stats");
                    writer.WriteAttributeString("Date", DateTime.Now.ToShortDateString());

                // Iterate all rows within another row
                HtmlNodeCollection rows = doc.DocumentNode.SelectNodes(".//tr/tr");
                for (int i = 0; i < rows.Count; ++i)
                {
                    // Iterate all columns in this row
                    HtmlNodeCollection cols = rows[i].SelectNodes(".//td[@class='statBox']");
                    for (int j = 0; j < 20; ++j)
                    {
                                switch (j)
                                {
                                    case 0:
                                        {
                                            writer.WriteStartElement("Player");
                                            writer.WriteAttributeString("Rank", cols[j].InnerText.Trim()); break;
                                        }
                                    case 1: writer.WriteElementString("Name", cols[j].InnerText.Trim()); break;
                                    case 2: writer.WriteElementString("Team", cols[j].InnerText.Trim()); break;
                                    case 3: writer.WriteElementString("Pos", cols[j].InnerText.Trim()); break;
                                    case 4: writer.WriteElementString("GP", cols[j].InnerText.Trim()); break;
                                    case 5: writer.WriteElementString("G", cols[j].InnerText.Trim()); break;
                                    case 6: writer.WriteElementString("A", cols[j].InnerText.Trim()); break;
                                    case 7: writer.WriteElementString("PlusMinus", cols[j].InnerText.Trim()); break;
                                    case 8: writer.WriteElementString("PIM", cols[j].InnerText); break;
                                    case 9: writer.WriteElementString("PP", cols[j].InnerText); break;
                                    case 10: writer.WriteElementString("SH", cols[j].InnerText); break;
                                    case 11: writer.WriteElementString("GW", cols[j].InnerText); break;
                                    case 12: writer.WriteElementString("OT", cols[j].InnerText); break;
                                    case 13: writer.WriteElementString("Shots", cols[j].InnerText); break;
                                    case 14: writer.WriteElementString("ShotPctg", cols[j].InnerText); break;
                                    case 15: writer.WriteElementString("TOIPerGame", cols[j].InnerText); break;
                                    case 16: writer.WriteElementString("ShiftsPerGame", cols[j].InnerText); break;
                                    case 17: writer.WriteElementString("FOWinPctg", cols[j].InnerText); break;

                                }
                            }
                        }
                        writer.WriteEndElement();
                    }
                    writer.WriteEndElement();
                    writer.Flush();
                }
                finally
                {
                    if (writer != null)
                        writer.Close();
                }
            }
        }
    }

提供以下 XML 文件作為輸出:

which gives the following XML file as an output:

<?xml version="1.0" encoding="utf-8" ?> 
<Stats Date="2011-01-01">
 <Player Rank="1">
  <Name>Sidney Crosby</Name> 
  <Team>PIT</Team> 
  <Pos>C</Pos> 
  <GP>39</GP> 
  <G>32</G> 
  <A>33</A> 
  <PlusMinus>20</PlusMinus> 
  <PIM>29</PIM> 
  <PP>10</PP> 
  <SH>1</SH> 
  <GW>3</GW> 
  <Shots>0</Shots> 
  <ShotPctg>154</ShotPctg> 
  <TOIPerGame>20.8</TOIPerGame> 
  <ShiftsPerGame>21:54</ShiftsPerGame> 
  <FOWinPctg>22.6</FOWinPctg> 
 </Player>
</Stats>
