Question

I am trying to load the template file my SPDocumentLibrary has set, do some transforms in OpenXML then save it back to the library as a document. I think I have all the steps down except reading the template. I don’t know the “correct” way to open it (I could just use a WebClient to download it but it makes me feel dirty just typing that). Here is what I have so far.

public string GetOrGenerateChecklist(string PracticeName, string ContractID, string EducationDate, string MainContactInfo, string Address)
{
    using (SPWeb web = SPContext.Current.Web)
    {
        SPDocumentLibrary list = (SPDocumentLibrary)web.Lists["Educator Checklists"];
        var templetAddr = String.Concat(web.Url, '/', list.DocumentTemplateUrl);
        SPQuery query = new SPQuery();
        query.Query = string.Concat(
                                //Snip
                                   );
        var items = list.GetItems(query);
        //if document exists return existing document.
        if (items.Count > 0)
            return String.Concat(web.Url, "/Educator Checklists/", PracticeName, " - ", ContractID, ".docx");

        MemoryStream documentStream;

        //copy the stream to memory
        using (Stream tplStream = ????????) //<-------   my problem
        {
            documentStream = new MemoryStream((int)tplStream.Length);
            CopyStream(tplStream, documentStream);
            documentStream.Position = 0L;
        }
        using (WordprocessingDocument template = WordprocessingDocument.Open(documentStream, true))
        {
            template.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
            MainDocumentPart mainPart = template.MainDocumentPart;
            mainPart.DocumentSettingsPart.AddExternalRelationship(
                "http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate",
                new Uri(templetAddr, UriKind.Absolute));

            ReplaceText(mainPart, "#PracticeName#", PracticeName);
            ReplaceText(mainPart, "#EducationDate#", EducationDate);
            ReplaceText(mainPart, "#MainContactInfo#", MainContactInfo);
            ReplaceText(mainPart, "#Address#", Address);
        }
        documentStream.Position = 0L;
        list.RootFolder.Files.Add(String.Concat(PracticeName, " - ", ContractID, ".docx"), documentStream);

        return String.Concat(web.Url, "/Educator Checklists/", PracticeName, " - ", ContractID, ".docx");
    }

}

So my question is how do i get the template stored at templetAddr loaded in to the memory stream?

Also I am fairly new to sharepoint so if you see any other big mistakes I have made please let me know.
