GeneralHelp for publish , Wrong position of source code. Pin

Hi editor.

I write a article use the following HTML code, when I publish , I find all source code (include XML and C#) move to the end automatic ,why?



<ul class="Download">
<li><a href="XLineCounter2010/XLineCounter.zip">Download XLineCounter - 313.13 KB</a></li>
</ul>

<h2>Introduction</h2>

<p ><span >XLineCounter is a open source C# program to analyze source code files and count number of source code line. It can count number of source line, comment line and blank line.</span></p>

<h2>Background</h2>

<p ><span >Million of programmers work hard year after year, and write many source codes in C++, C#, VB or Delphi. Some times they want know how many lines of those source code on earth. Of cause they can not count line by line, so they need a tool to count source lines.</span></p>

<h2>XLineCounter</h2>

<p ><span >Today, source code file is not alone, many source code file construct a project, and the compiler handle the project and generate program file.</span></p>

<p ><span >For example, in VS.NET2005, People create a C# project which file name’s extension is csproj, and add many C# source file to the C# project.</span></p>

<p ><span >XLineCounter need to analyze develop project file and get a list of source code file, also equip source code analyzer which can analyze source code like VB , C# or Pascal. So I design XLineCounter structure as the following shape.</span></p>

<p ><span ><img height="391" alt="XLineCounter_Structure.gif" src="XLineCounter2010/XLineCounter_Structure.gif" width="552" /></span></p>

<p ><span >There are two stresses in XLineCounter: first, analyze project file and get file list; second, analyze source file use specify syntax.</span></p>

<p ><span >For example, a C# .NET2005 project file in XML format, There is a sample.</span></p>

<p ><span >
<pre lang="XML">
&lt;Project DefaultTargets="Build"
xmlns="http://schemas.microsoft.com/developer/msbuild/2003"&gt;
&lt;PropertyGroup&gt;
&lt;AssemblyName&gt;CellViewLib&lt;/AssemblyName&gt;
&lt;/PropertyGroup&gt;
&lt;ItemGroup&gt;
&lt;Reference Include="System"&gt;
&lt;Name&gt;System&lt;/Name&gt;
&lt;/Reference&gt;
&lt;/ItemGroup&gt;
&lt;ItemGroup&gt;
&lt;Content Include="App.ico" /&gt;
&lt;Compile Include="frmTestCellView.cs"&gt;
&lt;SubType&gt;Form&lt;/SubType&gt;
&lt;/Compile&gt;
&lt;EmbeddedResource Include="frmTestCellView.resx"&gt;
&lt;DependentUpon&gt;frmTestCellView.cs&lt;/DependentUpon&gt;
&lt;SubType&gt;Designer&lt;/SubType&gt;
&lt;/EmbeddedResource&gt;
&lt;/ItemGroup&gt;
&lt;/Project&gt;
</pre>
</span></p>

<p ><span >To this XML document, I can execute XPath “Project/ItemGroup/Compile” and get a list of C# source file name. So I write the following C# code.</span></p>

<p >

<span >

<pre lang="CS">
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();

{
project.ProjectFileName = strFileName;
project.RootPath = System.IO.Path.GetDirectoryName(strFileName);
ProjectFile ProjFile = new ProjectFile();
ProjFile.FileName = System.IO.Path.GetFileName(strFileName);
ProjFile.FullFileName = strFileName;
ProjFile.Style = FileStyle.None;
project.Files.Add(ProjFile);

System.Xml.XmlNamespaceManager ns = new System.Xml.XmlNamespaceManager(doc.NameTable);
ns.AddNamespace("a", "http://schemas.microsoft.com/developer/msbuild/2003");

System.Xml.XmlNode NameNode = doc.SelectSingleNode("a:Project/a:PropertyGroup/a:AssemblyName", ns);
if (NameNode != null)
{
project.Name = NameNode.InnerText;
}
foreach (System.Xml.XmlElement element in doc.SelectNodes("a:Project/a:ItemGroup/*[name()='Compile' or name()='None' or name()='EmbeddedResource' or name()='Content']", ns))
{
string file = element.GetAttribute("Include");
ProjectFile NewFile = new ProjectFile();
NewFile.FileName = project.FixFileName(file);
if (System.IO.Path.IsPathRooted(file))
{
NewFile.FullFileName = file;
}
else
{
NewFile.FullFileName = System.IO.Path.Combine(project.RootPath, file);
}
if (element.Name == "Compile")
{
NewFile.Style = FileStyle.SourceCode;
}
else if (element.Name == "EmbeddedResource")

}
else
{
NewFile.Style = FileStyle.None;
}
project.Files.Add(NewFile);
}//foreach
}
</pre>

</span></p>

<p ><span >Use this code , XLineCounter can get file list from C#2005 project file. In the same way, XLineCounter can analyze VB.NET2005, VB6.0, Delphi project file and get source code file list.</span></p>

<p ><span >Next, XLineCounter need analyze source code with some kind of syntax. For example, There are some C# source code as the following.</span></p>
