Remove Namespace tags from RTF field Data

Question

RTF Text field is Adding Namespace Tags to HTML Items

<P>This is Text</p>

and SDL is converting it into

<p xmlns="http://www.w3.org/1999/xhtml">This is Test</p>

and need help to remove following namespace tag from output.

So far i have created a TBB to replace text using

 var fields = new ItemFields(cp.Content, cp.Schema);
            foreach (var field in fields)
            {
                if (field is XhtmlField)
                {
                    XhtmlField xhtmlField = field as XhtmlField;
                    xhtmlField.Value = TemplateUtilities.ResolveRichTextFieldXhtml(xhtmlField.Value);
                }
            }

but still output contains same Field value and need a way to replace this output.

Update: I am able to delete Namespaces using XML methods,but receiving errors during DD4T-Generate dynamic component Presentation TBB.Following TBB will remove Namespace tags from DD4T Output.

Final Solution:

                Item item = package.GetByName(Package.OutputName);
                if (item != null)
                {
                    string output = item.GetAsString();
                    //Following regex replace xmlns strings from output.
                    string strXMLPattern = "\\s+xmlns\\s*(:\\w)?\\s*=\\s*\\\\\"(?<url>[^\\\"]*)\\\\\"";
                    var matchCol = Regex.Matches(output, strXMLPattern);
                    foreach (var match in matchCol)
                        output = output.Replace(match.ToString(), "");
                    package.Remove(item);
                    package.PushItem(Package.OutputName, package.CreateStringItem(ContentType.String, output));
                }

Answer 1

Welcome, Mahesh. Try the Convert XML to XHTML Template Building Block, which is separate from Default Finish Actions.

Otherwise run Template Builder to confirm how your Output changes for each TBB.

Answer 2

Your Regex looks overly complex, but does seems to work fine on plain XHTML.

However, if you're using DD4T, the XHTML will be embedded in JSON. As a result, the double quotes will be escaped (preceded by a backslash), in which case the Regex no longer works.

Just obtain the DD4T JSON and test it using an online Regex tester, for example: http://regexstorm.net/tester

Refer to this article might help some of the answers - Unwanted Namespaces in Rendered Output

Alternatively, you could also use XmlDocument to load the XHTMLValue to process to remove the Namespaces.

Example:

    private String RemoveNameSpace(String xml)
    {
        if (!String.IsNullOrEmpty(xml))
        {
            XmlDocument xdoc = new XmlDocument();
            xdoc.LoadXml("<root>"+xml+"</root>");
            xdoc.LoadXml(xdoc.RemoveNameSpaces());
            return xdoc.SelectSingleNode("/root").InnerXml;
        }
        else
        {
            return String.Empty;
        }
    }

I hope it helps
