Font color problem with HTML table

Aspose.Words Product Family
#1

Hello Team,

We are using aspose 7.1.0.0 to generate documents.
We are facing problem with HTML table and the font color applied to it.

We are using InsertHTML() method to render text strings.
Before inserting the text we provide font color as “Red” or “Blue”, but in the output entire string does not take that color, rather just the first table is in the specified color and rest of the text is in black

Attached are the document output for your reference with the HTML string we are using.

Hello,
I have gone through the link you have provided. Link gives information about saving and re-loading the document in HTML format. Then using the font changer, however this is not the case with the problem we are facing which is related to color of the text.
Also it is not possible for us to save/reload the document as the documents are generated at runtime depending upon the settings.
Kindly suggest what can be done in this regards.

Thanks,

Hello

Thank you for additional information. In your case, you insert HTML in to the document and then using FontChanger you can easily change font color for whole document. All that you need is modifying FontChanger in order to change font color.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
string html = File.ReadAllText("yourHTML.html");
builder.InsertHtml(html);
// Create an object that inherits from the DocumentVisitor class.
FontChanger changer = new FontChanger(Color.Red);
// Get the model to accept a visitor.
// The model will iterate through itself by calling the corresponding methods
// on the visitor object (this is called visiting).
doc.Accept(changer);
// Save output document
doc.Save("out.doc");

Best regards,

Hello,Does this mean we have to use FontChanger irrespective of having HTML contents in the input string?
As string html may contain

html = "This is test text";

or

html = "<html><body><table><tr><td><font size="2" color="Blue">Test Test</font></td></tr></table></body></html>";

Also we do not have specific .html file. for the Text to be printed on report we simply call InsertHTML() method of documentbuilder.
Please suggest,

Hello

Thanks for your request. You can use InsertHtml method to insert an HTML fragment or whole HTML document. You should use FontChanger after inserting HTML into the document. It does not matter which way of inserting HTML you are using. You can read HTML from a file or inset as a string.
Best regards,

Hello,

Is it necessary to set and use fontchanger after the InsertHTML methos?
As in our application, we have custom objects which are used to format the paragraph, set the font etc and finally we call InsertHTML method.

Therefore we do not get font related info when we are in the method where InsertHTML method is used.

Hi there,
Thanks for your inquiry.
Yes, the visitor will change the font of all content visited during the enumeration. In this case, since the sample above is run on the document (doc.Accept) this will visit all nodes in the document and change the font for all appropriate nodes.
You can try running the class on just the particlar node or nodes that are inserted by the InsertHtml method but this may be hard if there are many nodes inserted. Instead you may want to take a look at the method used in this post here which may be easier.
Thanks,
