Hi, I’m evaluating Aspose.words and have hit a stumbling block.
We replace strings (%[*] ) in a Word Doc, with data that may itself contain tags that subsequently need to be replaced. For example, we might replace "%[CBS]" with “A line of checkboxes eg, !CB! and another !CB! and one more for good measure !CB!”
So we first replace %[*] with the string above and then search again for !CB!
I have the code working and the docx displays the checkboxes but the issue is all 3 checkboxes appear at the start of the text.
Eg:
"XXX A line of checkboxes eg, and another and one more for good measure. " where X is a checkbox object.
I assume this is occurring because the Checkbox object has to exist outside the run so is there any easy way to break the run up and ensure they get inserted in the correct position within the string?
Code I’m using is below.
Many thanks!
DocumentBuilder builder = new DocumentBuilder((Document)args.MatchNode.Document);
builder.MoveTo(args.MatchNode);
builder.InsertCheckBox("", "true", 0);
@Warrick Could you please attach your input and expected output documents here for our reference? We will check your documents and provide you more information.
Hi Alexey,
I’ve figured it out now and the doc is being created identically to our old Word versions now.
I split the runs and ensured all variables for replacement were in their own run.
Thanks,
Warrick
I have run into a different issue.
I have a document with 2 sets of different content between "{{" and "}}" strings. Refer attached: duplicate_range.docx (12.8 KB)
We need to be able to duplicate the content between each {{ }} range multiple times but for now I’m struggling just to duplicate once.
When I run the attached code, it errors out with:
System.ArgumentException: ‘Cannot insert a node of this type at this location.’
Can you point me in the right direction?? I’m a newcomer to .NET and C# so I trust I have the syntax correct.
Thanks, Warrick

@Warrick You should create a document from the extracted nodes and using DocumentBuilder.InsertDocument method. For example see the following code:
Document doc = new Document(@"C:\Temp\in.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
// Replace start and end tags with themsefs to make them to be represented as a separate Run nodes.
FindReplaceOptions opt = new FindReplaceOptions();
opt.UseSubstitutions = true;
doc.Range.Replace(new Regex(@"(\{\{)|(\}\})"), "$0", opt);
// Now select start and end tags.
List<Run> runs = doc.GetChildNodes(NodeType.Run, true).Cast<Run>().ToList();
List<Run> startTags = runs.Where(r => r.Text == "{{").ToList();
List<Run> endTags = runs.Where(r => r.Text == "}}").ToList();
for (int i = 0; i < startTags.Count; i++)
{
Run start = startTags[i];
Run end = endTags[i];
// Exrtact Content between start and end tags
List<Node> contentNodes = ExtractContentHelper.ExtractContent(start, end, true);
// Create document from extracted nodes.
Document extractedContent = ExtractContentHelper.GenerateDocument(doc, contentNodes);
// Insert extracted content after the end tag several times.
builder.MoveTo(end.NextSibling != null ? end.NextSibling : end.ParentNode);
for (int j = 0; j < 5; j++)
builder.InsertDocument(extractedContent, ImportFormatMode.UseDestinationStyles);
}
doc.Save(@"C:\Temp\out.docx");
Thanks so much Alexey!
You make it look easy and have obviously done this many times
It works like a charm.
One other question; what if I want to delete all nodes between start and end for one of the {{…}} groups?
I tried the following but it only deleted the first paragraph and left the table.
Hi Alexy,
I really appreciate the super fast response. 10:30pm here so time to stop for the night.
Thhe code is better, with the end }} being removed but try with the attached docx. There are tab characters in the line " Subtest Name Score Types and Scores" that I suspect are causing the issue. Is currentNode being set to null when it reads these perhaps??
@Warrick There is an easier way to remove the range. The following code works fine with the attached document:
// Remove the range from the source document.
// Wrap the ramge into a bookmark and then remove bookmakr content by setting it's text.
string tempBookmarkName = $"tmp_bookmark_{i}";
start.ParentNode.InsertBefore(new BookmarkStart(doc, tempBookmarkName), start);
end.ParentNode.InsertAfter(new BookmarkEnd(doc, tempBookmarkName), end);
doc.Range.Bookmarks[tempBookmarkName].Text = "";
doc.Range.Bookmarks[tempBookmarkName].Remove();
It wraps the range into a temporary bookmark, then content is removed by setting text of the bookmark to empty string and finally removes the temporary bookmark.
