Read htm file and write to txt

Nikos Athanasakis

Dear all ,

I have a problem with my csharp project. I have written a project in Csharp, which it reads from htm file and write to txt file. My problem is that it doesn't write all the lines it reads htm. Total line 1505 and in txt 1285.

thank you

Hi Nikos, may I not have time to help you but you can and I see that you make some processing in content, so

Open in Visual Studio Code the original html file,
and the result that you make.

Look where is missing content, onde you see where it is cutting information you create a debug stop with info in cell.InnerText, like: (cell.InnerText.Contains("xxxxyyyyy")) - this is in Visual Studio IDE - let me know if you don't know do this.

Once you found where is the problem, you can make a fix for that.

Good luck.

But there are missing lines?

When you read an Html file it can miss char(10) that is a break line that notepad reads as a new line, for example.

but to help you,

show me your code.

Best,

Jeff
