Sorting Table of Content Alphabetically using .NET

Aspose.Words Product Family

Hi

I have an Index file in which is not sorted alphabetically. Each row within an Index is a paragraph. I want to sort it alphabetically and update it in the same document. I have gone through some suggestion mention in different topics but doesn’t seem to be working.

E.G Input:

Active surveillance XXX

Absolute risk XXX

Adjustment XXX

      indirect XXX

      direct XXX

expected output:

Absolute risk XXX

Active surveillance XXX

Adjustment XXX

       direct XXX

      indirect XXX

Unfortunately, Aspose.Words does not provide API to sort paragraphs by text. Could you please ZIP and attach your input and expected output Word documents? We will then log this missing feature in our issue tracking system according to your requirement.

I couldn’t find any implementation, so I did mine which is working as expected. Here is the code for it:

 private void ProcessParagraphSorting(Document doc)  {

        const string sortAsc = "SortParagraphAsc";
        const string sortDesc = "SortParagraphDesc";

        var sdts = doc.GetChildNodes(NodeType.StructuredDocumentTag, true)
                     .Select(x => x as StructuredDocumentTag)
                     .Where(x => GetSdtTag(x) == sortAsc || GetSdtTag(x) == sortDesc);

        foreach (var sdt in sdts)
        {
            var paras = sdt.GetChildNodes(NodeType.Paragraph, true)
                .Select(x => x as Aspose.Words.Paragraph);

            var clonedParas = paras.Select(p => (Aspose.Words.Paragraph)p.Clone(true)).ToList();

            // Sort text by text
            if (GetSdtTag(sdt) == sortAsc)
            {
                clonedParas.Sort((a, b) => string.Compare(a.Range.Text, b.Range.Text, StringComparison.OrdinalIgnoreCase));
            }
            else
            {
                clonedParas.Sort((a, b) => string.Compare(b.Range.Text, a.Range.Text, StringComparison.OrdinalIgnoreCase));
            }

            // Remove all current paragraphs from the SDT
            foreach (var para in paras)
            {
                para.Remove();
            }

            // Add cloned paragraphs in the desired sorting order
            foreach (var para in clonedParas)
            {
                sdt.AppendChild(para);
            }
        }
   }
