How to find font and color has been used for the string in whole word document
@siva1950 You can use Font properties to get font name, color and other formatting properties.
Default font properties applied to the document are accessible via StyleCollection.DefaultFont property.
Also, please see the following article to learn more about Aspose.Words Document Object Model:

Hi Alexey
Thank you for your information.But I was stucked some scenario
I have sharing sample code below and explain from there kindly help me
var replaceValue = objDocStructurePlanning.ValidationSummary(j, objEntitylst, t.DocType, mlTexts, true);
FindReplaceOptions optionsFrm = new FindReplaceOptions(FindReplaceDirection.Backward);
optionsFrm.ReplacingCallback = new ReplaceWithHtmlEvaluator(replaceValue.ToString());
mainDoc.Range.Replace(new Regex(@"<Validation Plan>"), String.Empty, optionsFrm);
In my document I have <Validation Plan> Tag .after some logic I have replace <Validation Plan> tag .replace code also I have shared below
private class ReplaceWithHtmlEvaluator : IReplacingCallback
{
internal ReplaceWithHtmlEvaluator(string html)
{
_html = html;
}
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((Aspose.Words.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((Aspose.Words.Run)currentNode, remainingLength);
runs.Add(currentNode);
}
DocumentBuilder builder = new DocumentBuilder((Aspose.Words.Document)e.MatchNode.Document);
builder.MoveTo((Aspose.Words.Run)runs[0]);
// Replace '<CustomerName>' text with a red bold name.
//builder.InsertHtml(_html);
foreach (Aspose.Words.Run run in runs)
run.Remove();
var parts = Regex.Split(_html, @"(<h1>[\s\S]+?<\/h1>)|(<h2>[\s\S]+?<\/h2>)|(<h3>[\s\S]+?<\/h3>)").Where(l => l != string.Empty).ToArray();
foreach (var splitHtml in parts)
{
InsertNewPageWithHeading(builder, splitHtml);
}
return ReplaceAction.Skip;
}
}
My Expectation is <Validation Tag> Font details I need to get.Kindly Help on this scenario
@siva1950 If you need to get font details of the matched node you can use code like this:
// This is a Run node that contains either the beginning or the complete match.
Node currentNode = e.MatchNode;
// Get the matched node font details
Font currentFont = ((Run)currentNode).Font;
// Here you can get font name and other formatting properties of the matched node.
Console.WriteLine(currentFont.Name);
Console.WriteLine(currentFont.Bold);
Console.WriteLine(currentFont.Color);
// etc....
Great ,Thank you So much what I have Expected I got it now. Appreciating more
Last Question
Before Request Which I have shared code .In that code I have been Using few line at End
foreach (var splitHtml in parts)
{
InsertNewPageWithHeading(builder, splitHtml);
}
this InsertNewPageWithHeading Method I have been Mainly using for Generating Toc Let me explain I have been sharing code for this InsertNewPageWithHeading Method

From this Method I am Finding Header H1,H2,H3 Tag and passing to Documentbuilder For Generating TOC.
Normally I have been using follow Aspose Generating TOC and it Working Fine shared below code
builder.InsertTableOfContents("\\o \"1-4\" \\h \\z \\u");
wdMainDoc.Save(saveFilename);
but while Replacing Tag value Scenario the TOC is not Generated so I have followed this my custom Method “InsertNewPageWithHeading” and representing H1,H2,H3 for document builder
After Creating this InsertNewPageWithHeading I can able to generate the TOC.
Here Iam using Extra Method to avoid this method "InsertNewPageWithHeading " any other way is there or Whether Iam doing Incorrect way?
@siva1950 HTML h1-h6 tags are converted to the corresponding heading paragraphs when HTML is imported by Aspose.Words. So there is no need of additional processing. For example see the following code:
// Create document and DocumentBuilder.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert TOC.
builder.InsertTableOfContents("\\o \"1-3\" \\h \\z \\u");
// Inert page break (for demonstraction urposes)
builder.InsertBreak(BreakType.PageBreak);
// Insert HTML with headings:
builder.InsertHtml("<h1>This is heading 1</h1><h2>This is heading 2</h2><h3>This is heading 3</h3>");
// Update fields.
doc.UpdateFields();
// Save output document
doc.Save(@"C:\Temp\out.docx");
thanks,
Hi alexey
How to find wherther the document contains toc or not?
Kindly provide in c# code
@siva1950, please check this post: How to know the document contains TOC or not - #3 by carlos.molina

I have been try remove ms word document protection through aspose but I dont have any idea because I am using filestream.through filestream how to remove can you suggest code in c# more helpful for me
Hi alex
Greeting for the day !
Hi alex I have tried “Repeat as header at top of the each page” like when table continue next page.Table header should maintain be maintain.
I have Attached sample word document.I have tried with sample code but I have no luck
Aspose.Words.Document wdMainDoc = new Aspose.Words.Document(fileName.ToString());
DocumentBuilder builder = new DocumentBuilder(wdMainDoc);
BookmarkCollection bb = wdMainDoc.Range.Bookmarks;
foreach (Aspose.Words.Bookmark cc in bb)
{
if (cc.Name.Contains("TOC"))
{
builder.MoveToBookmark(cc.Name, false, true);
}
}
builder.InsertTableOfContents("\\o \"1-4\" \\h \\z \\u");
wdMainDoc.Save(saveFilename);
foreach (Aspose.Words.Tables.Table table in wdMainDoc.GetChildNodes(Aspose.Words.NodeType.Table, true))
{
table.FirstRow.RowFormat.HeadingFormat = true;
}
@siva1950 I tried using your document and the following code and everything seems to work as expected. Just to be sure, I changed the color of the first row:
Document doc = new Document("input.docx");
foreach (Table table in doc.GetChildNodes(NodeType.Table, true))
{
table.FirstRow.RowFormat.HeadingFormat = true;
foreach (Cell cell in table.FirstRow.Cells)
{
Shading shading = cell.CellFormat.Shading;
shading.Texture = TextureIndex.TextureSolid;
shading.ForegroundPatternColor = Color.Aqua;
}
}
doc.Save("output.docx");
In the code you provided, you set the header format after saving the document, maybe that’s the issue?
ok,but I need to find table with header. beacuse two column table taking as first header.but it not the table I have attached docx.kindly guide me on that
evidence.docx (147.0 KB)
@siva1950 In your case you can try checking whether all cells in the first row has the same background. For example, see the following code:
Document doc = new Document(@"C:\Temp\in.docx");
foreach (Table table in doc.GetChildNodes(NodeType.Table, true))
{
Cell firstCell = table.FirstRow.FirstCell;
bool considerAsHeaderRow = table.FirstRow.Cells.Cast<Cell>()
.All(c => c.CellFormat.Shading.BackgroundPatternColor == firstCell.CellFormat.Shading.BackgroundPatternColor);
if (considerAsHeaderRow)
table.FirstRow.RowFormat.HeadingFormat = true;
}
doc.Save(@"C:\temp\out.docx");
Additionally I need to validate if table contains first column header contain # then I need to add
table.FirstRow.RowFormat.HeadingFormat = true;
@siva1950 You can get text from the first cell of the first row and check it’s text. For example see the following code:
Cell firstCell = table.FirstRow.FirstCell;
string firstCellText = firstCell.ToString(SaveFormat.Text).Trim();
if (firstCellText.StartsWith("#"))
{
// Do something ..................
}
how to check the table contains two column in the document.if more than two I need to set true if less than or equal two column I need to set false
@siva1950 In MS Word table there is no “column” concept, each row in the table is independent and can contain any number of cells. If you are sure the first row has the same number of cells as the rest, you can simply check cells count in the first row.
