Alignment ignored if html contains a div

When the html text contains a

, the ParagraphAlignment is ignored.

See sample code for example.

Try removing the

and the alignment will work.

Please help. thanks.

public void AsposeTest()

{

Aspose.Words.License license = new Aspose.Words.License();

license.SetLicense("Aspose.Total.lic");

string someText = "Text before a div.

builder.ParagraphFormat.Alignment = ParagraphAlignment.Justify;

builder.InsertHtml(someText);

Note: same is also true for a

Hi Eric,


Thanks for your inquiry.

Please note that
Aspose.Words was originally designed to work with MS Word documents. Upon
processing HTML, some features of HTML might be lost. You can find a list of
limitations upon
HTML exporting/importing here:
http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/save-in-the-html-format.html

Moreover, I would suggest you try using Paragraph instances to be able to correctly apply paragraph formatting and for this please visit the following links for more details:
http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/aspose.words.paragraph.html
http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/aspose.words.paragraphformat.html

Also, please note
that DocumentExplorer is a very useful tool which easily enables us to
see the entire document structure. You can find DocumentExplorer in the
folder where you installed Aspose.Words e.g. C:\Program Files
(x86)\Aspose\Aspose.Words for
.NET\Demos\CSharp\DocumentExplorer\bin\DocumentExplorer.exe
. Please try using this tool to be able to view the final structure (DOM) of the document you generated by using the HTML string.

Please let us know if you need more information, We are always glad to help you.

Best Regards,

Hi Eric,

Thanks for your request. Starting from 9.5.0 version behavior of InsertHtml was changed. Now content inserted by Insert HTML does not inherit formatting specified in DocumentBuilder options. Whole formatting is taken from HTML snippet. If you insert HTML with no formatting specified, default formatting is used for inserted content. In your case, DIV and P tags are translated to paragraphs when you load your HTML and default formatting is used for these paragraphs.

Also if you looking to combine all formatting from the DocumentBuilder or another node automatically (like how InsertHtml behaved like in older versions) then you may want to look into using this code work around here.

Please let us know if you need more information, we will be glad to help you.

Best regards,

Alexey,

I appreciate your actually trying to address the issue I posted (Awais Hafeez's response was not relevant.

In fact, the information you provided looks promising if you could help me debug an error in the work-around code you referenced.

I have provided sample code (slightly modified from the previous sample). If there is no text before the first tag, I get the following error:

"Cannot return user defined styles by style identifier."

on line:

prop.SetValue(dest, prop.GetValue(source, null), null);

in

CopyFormatting()

In the following sample code that I provided, delete the following text "error occurs if no text prior to div"

and the error will occur. Note, I have included the work-around code in this post as well.

my code: ____________________________________

public void AsposeTest()

{

Aspose.Words.License license = new Aspose.Words.License();

license.SetLicense("Aspose.Total.lic");

string someText = "error occurs if no text prior to div

text in a div
Lorem ipsum";

string css = "" + ".test{color:Red;}" + "";

Document doc = null;

DocumentBuilder builder = null;

doc = new Document();

builder = new DocumentBuilder(doc);

InsertHtmlWithBuilderFormatting(builder, css + someText);

doc.Save(Response, "filename.doc", ContentDisposition.Attachment, SaveOptions.CreateSaveOptions(SaveFormat.Doc));

Response.End();

}

Hi there,


Thanks for your inquiry.

You can fix this issue just by wrapping the SetValue call in a try catch block and ignoring any errors. The issue occurs because the reflection code attempts to set a user defined style by style identifier which is not allowed.

Thanks,
