Text to HTML with html within the text

I am trying to convert a text doucment that has text along with HTML to an HTML document. The results are not what I expected, I lose the text of the html tags, which are supposed to be considered text. I have tried to using LoapOptions with the LoadFormat set as Text, but I get the same result.
.NET

Aspose.Words.LoadOptions lo = new Aspose.Words.LoadOptions(Aspose.Words.LoadFormat.Text,null,null);
Document doc = new Document(filepath, lo);
doc.Save(newfilepath, Aspose.Words.SaveFormat.Html);

Example: test.txt
Here is simple html text:

<html>
 <body>
 1234567890
 </body>
</html>

Hi,

Thanks for your inquiry. After an initial test with Aspose.Words 13.5.0, I was unable to reproduce this issue on my side. Please upgrade to the latest version of Aspose.Words from the following link:
https://releases.aspose.com/words/net

I hope, this helps.

Moreover, I have attached sample input/output documents here for your reference. If we can help you with anything else, please feel free to ask.

Best regards,

Thank you for responding to my issue. I have downloaded the lastest Words . NET (13.5) and my results are the same. Below is my test file and the output along with the code I used to generate the output.
Input: test.txt
Here is simple html text:

<html>
<body>
    1234567890
</body>
</html>

Output: test.html & test2.html(formatted for display)

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta http-equiv="Content-Style-Type" content="text/css" />
    <meta name="generator" content="Aspose.Words for .NET 13.5.0.0" />
    <title>
    </title>
</head>
<body>
    <div>
        <p style="margin:0pt"><span style="font-family:'Times New Roman'; font-size:12pt"> Here is simple html text: 1234567890 </span></p>
    </div>
</body>
</html>

Program.cs:

Document doc;
try
{
    doc = new Document("C:\\test.txt");
    doc.Save("C:\\test.html");
    doc.Save("C:\\test2.html", Aspose.Words.SaveFormat.Html);
}
catch (Exception e)
{
    Console.WriteLine("Error: e.Message");
}

Hi,

Thanks for the additional information. Please specify the LoadOptions and try run the following code snippet. This will fix the issue:

Aspose.Words.LoadOptions

loadOptions = new Aspose.Words.LoadOptions();
loadOptions.LoadFormat = LoadFormat.Text;
Document doc = new Document(@"C:\Temp\Docs\test.txt", loadOptions);
doc.Save(@"C:\Temp\docs\outputputfixed.html");

Best regards,
