How to get the field code view of a Word stream to display mergefield code in html

Hello,

Is that possible to load a Word document from a binary tab and get the ALT F9 view of the Word document in a string ?

I achieved to diplay from a stored document :
<<myMergeField>>
but I rather have
{ MERGEFIELD myMergeField \* MERGEFIELD } shown

The main point for I is to be able to show the user the conditionnal IF instead of the view of the mergefield if :
{ IF "1"="HelloWorld" "Test" "Hello" }
instead of 1 1 1

Thanks in advance.
Regards.

Hi Emilien,

Thanks for your inquiry. Please use the following code snippet to get the field as <>. Hope this helps you . Please let us know if you have any more queries.

///

/// Retrieves the field code from a field.
///
/// The field start of the field which to gather the field code from
///
private static string GetFieldCode(FieldStart fieldStart)
{
    StringBuilder builder = new StringBuilder();
    for (Node node = fieldStart; node != null && node.NodeType != NodeType.FieldSeparator &&
        node.NodeType != NodeType.FieldEnd; node = node.NextPreOrder(node.Document))
    {
        // Use text only of Run nodes to avoid duplication.
        if (node.NodeType == NodeType.Run)
            builder.Append(node.GetText());
    }
    return builder.ToString();
}
private static string GetMailMergeField(FieldStart fieldStart)
{
    StringBuilder builder = new StringBuilder();
    Node Separator = fieldStart.NextPreOrder(fieldStart.Document);
    while (Separator.NodeType != NodeType.FieldSeparator)
        Separator = Separator.NextPreOrder(fieldStart.Document);
    for (Node node = Separator; node != null &&
        node.NodeType != NodeType.FieldEnd; node = node.NextPreOrder(node.Document))
    {
        // Use text only of Run nodes to avoid duplication.
        if (node.NodeType == NodeType.Run)
            builder.Append(node.GetText());
    }
    return builder.ToString();
}

Document doc = new Document(MyDir + "in.docx");
FieldStart fStart = (FieldStart) doc.GetChild(NodeType.FieldStart, 0, true);
string field = GetMailMergeField(fStart);

Hello, thanks for your quick reply. Sadly it doesn’t solve my matter.

I got that done already but i would like to get the mergiefield real value :
It’s that possible to get the { MERGEFIELD myMergeField \* MERGEFIELD } string ? Instead of <<myMergeField>> ?

Indead the resultat of << >> for conditionnal mergefield (IF) doesn’t work fine.

My aim is to display a text to my user (in HTML format) like that :
"Dear {MERGEFIELD name \* MERGEFIELD },
hello world {MERGFIELD aText \* MERGEFIELD }
"

(Not
"Dear <<name>>,
hello world <<aText>>")
So my user can edit his word model in a textArea ?

Thanks in advance.

Hi Emilien,

Thanks for your inquiry. I share two method in my last post.

  1. GetFieldCode: This method will return the value as MERGEFIELD myMergeField \* MERGEFORMAT

  2. GetMailMergeField: This method return the value as <<myMergeField>>

So, in your case, I suggest you to use GetFieldCode method. Hope this helps you. If you still face problem, please manually create your expected input and output documents and attach here for reference. I will share the code according to your requirements.
