Hello

I have a problem with insert of StructuredDocumentTag, or find and replace some text with StructuredDocumentTag.

Whatever I do, I get different exceptions. What I want is:

1.) find any text and replace this text with StructuredDocumentTag

2.) Navigate through document and insert StructuredDocumentTag an specific Position. What are valid nodetype for (parent) insert operation?

What do I make wrong …?

Thanks

Stephan

Hi Stephan,

Thanks for your inquiry. Please use the following code to achieve this:

Document doc = new Document(MyDir + @"document.docx");
// 1. find and replace some text with some StructuredDocumentTag
doc.Range.Replace(new System.Text.RegularExpressions.Regex("{VAR}"), new StructuredTagReplaceEvaluator(), false);
doc.Save(MyDir + @"out.docx");

private class StructuredTagReplaceEvaluator : Aspose.Words.IReplacingCallback
{
    Aspose.Words.ReplaceAction Aspose.Words.IReplacingCallback.Replacing(Aspose.Words.ReplacingArgs e)
    {
        // This is a Run node that contains either the beginning or the complete match.
        Node currentNode = e.MatchNode;
        // The first (and may be the only) run can contain text before the match,
        // in this case it is necessary to split the run.
        if (e.MatchOffset > 0)
            currentNode = SplitRun((Run)currentNode, e.MatchOffset);
        // This array is used to store all nodes of the match for further removing.
        ArrayList runs = new ArrayList();
        // Find all runs that contain parts of the match string.
        int remainingLength = e.Match.Value.Length;
        while ((remainingLength > 0) &&
            (currentNode != null) &&
            (currentNode.GetText().Length <= remainingLength))
        {
            runs.Add(currentNode);
            remainingLength = remainingLength - currentNode.GetText().Length;
            // Select the next Run node.
            // Have to loop because there could be other nodes such as BookmarkStart etc.
            do
            {
                currentNode = currentNode.NextSibling;
            }
            while ((currentNode != null) && (currentNode.NodeType != NodeType.Run));
        }
        // Split the last run that contains the match if there is any text left.
        if ((currentNode != null) && (remainingLength > 0))
        {
            SplitRun((Run)currentNode, remainingLength);
            runs.Add(currentNode);
        }
        StructuredDocumentTag plainText = new StructuredDocumentTag((Document)e.MatchNode.Document, SdtType.PlainText, MarkupLevel.Inline);
        DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);
        builder.MoveTo((Run)runs[runs.Count - 1]);
        builder.InsertNode(plainText);
        // Now remove all runs in the sequence.
        foreach (Run run in runs)
            run.Remove();
        return ReplaceAction.Skip;
    }
}

///
/// Splits text of the specified run into two runs.
/// Inserts the new run just after the specified run.
///
private static Run SplitRun(Run run, int position)
{
    Run afterRun = (Run)run.Clone(true);
    afterRun.Text = run.Text.Substring(position);
    run.Text = run.Text.Substring(0, position);
    run.ParentNode.InsertAfter(afterRun, run);
    return afterRun;
}

I hope, this helps.

Best regards,
