Getting code from all (closed) files in solution in Visual Studio SDK - visual-studio-2012

Question

I'm trying to get and edit the code of all the html-files in the project
i found a way to loop over all ProjectItems
IEnumerator Projects = _applicationObject.Solution.Projects.GetEnumerator();
while (Projects.MoveNext())
{
IEnumerator Items = ((Project)Projects.Current).ProjectItems.GetEnumerator();
Queue<ProjectItem> ProjectItems = new Queue<ProjectItem>();
while (Items.MoveNext())
{
ProjectItem SubItem = (ProjectItem)Items.Current;
try
{
if (SubItem.Document != null) DocumentIndex.Add(SubItem.Document);
}
catch (Exception Exception)
{
Console.WriteLine(Exception.Message);
//ignore
}
ProjectItems.Enqueue(SubItem);
}
//follow the tree down
while (ProjectItems.Count != 0)
{
ProjectItem ProjectItem = ProjectItems.Dequeue();
if (ProjectItem.ProjectItems != null)
{
foreach (ProjectItem SubItem in ProjectItem.ProjectItems)
{
ProjectItems.Enqueue(SubItem);
try
{
try
{
SubItem.Open(SubItem.Kind);
DocumentIndex.Add(SubItem.Document);
}catch(Exception Ex){
Console.WriteLine(Ex.Message);
}
}
catch (Exception Exception)
{
Console.WriteLine(Exception.Message);
//ignore
}
}
}
}
}
now i can't get to the code of the files that are not open in an editor window.
how do i get and edit the code of "not opened" projectItems?
how do i detect if a file is a code file? (eg: .cs, .html, .htm, .asp, ....

You must open the ProjectItem that you want to read or edit
DTE dte = (DTE)Package.GetGlobalService(typeof(DTE));
var project = dte.Solution.Projects.Item(1);
var projectItems = project.ProjectItems;
var anyItem = projectItems.Item(0);
Window anyItemWindow = anyItem.open()
var selection = anyItem.Document.Selection as TextSelection;
selection.SelectAll();
Console.WriteLine(selection.Text) // All code
anyItem.Document.Close() //Close Document
if you don't open the ProjectItem anyItem.Doument is null.
Note: selection.Insert("") can be used to change the code
