Word Doc: Convert Special Tag to Bookmark and Link to Bookmark

I have a word document with many special tags that represent
a bookmark and a link to a bookmark. I want to replace these tags with a proper bookmark
and link to bookmarks. (see attached example doc: special_tags.docx)

here’s what i mean…

Bookmark Tag:
The format of a bookmark tag in my word doc is []
where x is the bookmark.

for example:
[] = This represents a bookmark called b1

How can I scan my word document and find all Tags like this [] and
replace them with a correct word bookmark.

Link to Bookmark Tag:
The format for an internal link to a bookmark is: [>T~x<]
where
T = the display text for the link
x = bookmark

for example:
[>Go to Special Offers~sp1<]

This tag should be replaced with a link that looks like this: Go to Special Offers

When the user CTRL+Clicks this link he jumps to the sp1 bookmark.

I have lots of these types of tags which were generated dynamically so i do not know
what the bookmark id is or the display text.

I have attached 2 docs as an example.
- Original word doc with tag: special_tags.docx
- The same document after the tags have been replaced: tags_converted.docx


Hi Nitin,


Thanks for your inquiry.
Nitin:
How can I scan my word document and find all Tags like this [] and replace them with a correct word bookmark.
Here is the code to achieve this.

Document doc = new
Document(@“C:\Temp\special_tags.docx”);<o:p></o:p>

// Replace tags with Bookmarks

doc.Range.Replace(new Regex("\\[<[a-z]+\\d>\\]"), new InsertBookmarkAtReplaceHandler(), true);

doc.Save(@"C:\Temp\out.docx");


private class InsertBookmarkAtReplaceHandler : 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);

}

string tagName = e.Match.Value.Replace("[<", "").Replace(">]", "");

DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);

builder.MoveTo(e.MatchNode);

builder.MoveTo((Run)runs[runs.Count - 1]);

builder.StartBookmark(tagName);

builder.EndBookmark(tagName);

return ReplaceAction.Replace;

}

///

/// 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;

}

}


Moreover, I am working over the second part of your request and will get back to you soon.

Best Regards,

Hi Nitin,


Thanks for your patience. For the second part of your problem, I think the following routine will serve the purpose.

private class LinkToBookmarkAtReplaceHandler : 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);

}

string tagName = e.Match.Value.Replace("[>", "").Replace("<]", "");

string[] splits = tagName.Split(new char[] { '~' });

string displayText = splits[0];

string bookmarkName = splits[1];

DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);

builder.MoveTo(e.MatchNode);

builder.MoveTo((Run)runs[runs.Count - 1]);

builder.InsertHyperlink(displayText, bookmarkName, true);

return ReplaceAction.Replace;

}

///

/// 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;

}

}


Best Regards,

That's fantastic! It worked.

Thank you so much!
