How to move document bulder to a string

Hi,

I have this scenario:

In a template I have a string like this: [[table_articles]]. Now I want to move my document builder here and insert a bookmark at this position and then remove the string.

How can I do this?

Best regards

Hi Robert,

Thanks for your inquiry. You can achieve your requirement by implementing IReplacingCallback interface. Please use the same approach shared at following documentation link to find text and insert the bookmark. See the highlighted code snippet below.
https://docs.aspose.com/words/java/find-and-replace/

Please read the following article about ‘Find and Replace’ and check the following code example for your kind reference.
https://docs.aspose.com/words/java/find-and-replace/

Hope this helps you. Please let us know if you have any more queries.

Document doc = new Document(MyDir + "in.docx");
doc.Range.Replace(new Regex((@"\[\[table_articles\]\]", RegexOptions.IgnoreCase), new ReplaceEvaluator(), false);
doc.Save(MyDir + "Out.docx");

public class ReplaceEvaluator : IReplacingCallback
{
    ReplaceAction IReplacingCallback.Replacing(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);
        }
        // Create Document Buidler 
        DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);
        builder.MoveTo((Run)runs[runs.Count - 1]);
        // Your code comes here
        builder.StartBookmark("MyBookmark");
        builder.Writeln("Text inside a bookmark.");
        builder.EndBookmark("MyBookmark");

        // Now remove all runs in the sequence.
        foreach (Run run in runs)
            run.Remove();
        // Signal to the replace engine to do nothing because we have already done all what we wanted.
        return ReplaceAction.Skip;
    }
    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;
    }
}
