Search and replace in a file – in memory

[gamartinParticipant]

I am trying to replace text in a template document in memory only, and it is not working.

For example the following will work (if I write the file to disk before doing the search and replace)

 using (WordprocessingDocument finalDoc = WordprocessingDocument.Open(destDocxFi.FullName, true))
            {
            TextReplacer.SearchAndReplace(newDoc, "<TitlePageGroupAndCode>", _caTitle, true);
            TextReplacer.SearchAndReplace(newDoc, "<TitlePageBargainingAgentName>", _bargainingAgentName, true);
            TextReplacer.SearchAndReplace(newDoc, "<TitlePageGroupName>", _groupName, true);
            TextReplacer.SearchAndReplace(newDoc, "<TitlePageExpiryDate>", _expiryDate, true);
            TextReplacer.SearchAndReplace(newDoc, "<CopyrightBargainingAgentName>", _bargainingAgentName, true);
}

However if I try to simply use the document in-memory as follows, it does not work:

 WmlDocument doc = HtmlToWmlConverter.ConvertHtmlToWml(defaultCss, usedAuthorCss, userCss, html, settings, null, null);
            //doc.SaveAs(destDocxFi.FullName);
            //doc = null;

            // grab our template based on language.
            var templatePath = Server.MapPath(String.Format("~/Content/{0}", 1 == 1 ? "CATemplate_English.docx" : "CATemplate_French.docx"));

            var templateDoc = new WmlDocument(templatePath);
            templateDoc.SearchAndReplace("<TitlePageGroupAndCode>", _caTitle, true);
            templateDoc.SearchAndReplace("<TitlePageBargainingAgentName>", _bargainingAgentName, true);
            templateDoc.SearchAndReplace("<TitlePageGroupName>", _groupName, true);
            templateDoc.SearchAndReplace("<TitlePageExpiryDate>", _expiryDate, true);
            templateDoc.SearchAndReplace("<CopyrightBargainingAgentName>", _bargainingAgentName, true);

            List<Source> sources = new List<Source>();
            sources.Add(new Source(templateDoc, true));
            sources.Add(new Source(doc, false));
            var newDoc = DocumentBuilder.BuildDocument(sources);
            
            //newDoc.SaveAs(destDocxFi.FullName);
            //newDoc = null;
            sources = null;

Any thoughts?

I have also tried to do the search and replace on the merged document, with the same issue: no text is replaced.

OK I was able to get this to work in memory. I guess the behaviour when you save the file is different than when you just work in memory.

I if do it thusly it works:

 // open our template and do our quick search and replace
            var templateDoc = new WmlDocument(templatePath);
            
            templateDoc = TextReplacer.SearchAndReplace(templateDoc, "<TitlePageGroupAndCode>", _caTitle, true);
            templateDoc = TextReplacer.SearchAndReplace(templateDoc, "<TitlePageBargainingAgentName>", _bargainingAgentName, true);
            templateDoc = TextReplacer.SearchAndReplace(templateDoc, "<TitlePageGroupName>", _groupName, true);
            templateDoc = TextReplacer.SearchAndReplace(templateDoc, "<TitlePageExpiryDate>", _expiryDate, true);
            templateDoc = TextReplacer.SearchAndReplace(templateDoc, "<CopyrightBargainingAgentName>", _bargainingAgentName, true);
