Error Message Question

jray9242 · 01-01-2018, 01:15 PM

When load my HTML into Sigil, I get the following error.

This page contains the following errors:

error on line 17 at column 16: Namespace prefix 'mbp' not declared
Below is a rendering of the page up to the first error.

I am using Notjohn's template and not sure if this is a problem.

These are the other 2 errors I get.

Error(prcgen):E24010: Hyperlink not resolved in toc (One possible reason can be that the link points to a tag with style display:none):C:\Users\Jim\AppData\Local\Temp\mbp_ 7E1_C_1F_12_34_1D_172_1748_2EC4_1\OEBPS\Text\Secti on0001.xhtml#

Error(prcgen):E24001: The table of content could not be built.

Thanks for the help.

PS

I am publishing to Amazon.

Epubs need to use xhtml (or html5 for epub3). Mbp: is not valid xhtml (or html5). It sounds like your html contains raw mobi markup to me.

I can't really help with Kindlegen/Previewer errors. I don't use it.

Ad mbp:
You have two options.
1. Find all <mbp:something> (for example <mbp:pagebreak/>) tags and remove them
2. Add in the appropriate files...
Now you probably have such an entry:

Code:

<html xmlns="http://www.w3.org/1999/xhtml">

Change to:

Code:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:mbp="www.mobipocket.com">

It does not make much sense, but the error should not appear.

Ad kindlegen.
You must check especially the file Section0001.xhtml and specific link from the TOC file.
The destination has a style display:none declared.

It can be a direct declaration, e.g.

PHP Code:


			
<h1 style="display: none">Title blah, blah, blah</h1>

or by CSS style:

PHP Code:


			
<h1 class="hidden-header">Title blah, blah, blah</h1>

with declared class:

Code:

.hidden-header {display: none;}

Of course, the style names will be different.

Thank you both for the information.I used mbp

agebreak for formatting based on Notjohn's blog on posting to Amazon.

I have posted this book before and didn't have a problem, but now I do.

Once I create the ePub. is there a reason for me to use Kinder Reader?

I will take your advice and apply these changes.

Thanks again.

I believe it formats the eBook page breaks.

This fixed one of my problems:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:mbp="www.mobipocket.com">

I don't use the <H1> so I will look at the TOC error again.

Thanks for the help.

jray9242 · 01-02-2018, 06:24 PM

Great news!

I now have no errors when I open it with the Kindle viewer.

Now I have to figure out why my TOC links are not working. They work in HTML and in Sigil but not with the Kindle viewer.

Thanks again all for the help!

I agree. Better to just remove that non-standard <mbp> code and stick with normal XHTML.

If you were trying to get page breaks, it would probably be best to use CSS.

HTML:

Code:

<p class="pagebreak">* * *</p>

CSS:

Code:

p.pagebreak {
	page-break-before: always;
}

Or just split each individual piece into its own HTML file (the only real universal solution to guarantee it will be on their own pages).

What's the code?

Side Note: Instead of using something like:

Code:

<p class="part">Part 1</p>
<p class="chapter">Chapter 1</p>

it is better to use <h1-h6> for chapters/subchapters:

Code:

<h1>Part 1</h1>
<h2>Chapter 1</h2>

Marking documents with headings will allow Sigil to generate a correct TOC very easily for you. It also brings many other long-term benefits.

Tex2002ans,

I did get everything working but think creating each chapter in a separate HTML might work better.

I will research this so I don't bother you all to much.

Thank you all very much for the help and will use CSS for my page breaks from here on out.

That really is the best and most easiest choice.

It is the only guaranteed way to work + it helps keep the filesizes of each HTML file small to help older devices (many older ereaders croak if the HTML file becomes larger than ~300 KB).

jray9242 · 01-03-2018, 10:21 AM

Let me ask this one last question.

Do I create each chapter as a standalone HTML complete with CSS and then merge them in Sigil?

I have been searching and haven't found any examples yet.

Thanks again.

Just use the Sigil split tool (manual) on the toolbar
OR
put

Code:

<hr class="sigil_split_marker" />

at the split point

I use Search and replace to insert the code when there is a good trap condition.
<F6> executes the split (do a save before, is a good practice)

Just keep every chapter in a seperate file.

Instead of having one giant HTML file like this:

Code:

<body>
<p class="pagebreak">Copyright info</p>

<p class="pagebreak">Chapter 1</p>
<p>Text in Chapter 1.</p>

<p class="pagebreak">Chapter 2</p>
<p>Text in Chapter 2.</p>
</body>

You want seperate HTML files:

copyright.xhtml:

Code:

[...]
<body>
<p>Copyright info</p>
</body>

Chapter1.xhtml:

Code:

[...]
<body>
<h2>Chapter 1</h2>
<p>Text in Chapter 1.</p>
</body>

Chapter2.xhtml:

Code:

[...]
<body>
<h2>Chapter 2</h2>
<p>Text in Chapter 2.</p>
</body>

As theducks said, you can use the Split at Cursor button:

Click image for larger version

Name: SigilSplitAtCursor.png
Views: 181
Size: 42.5 KB
ID: 161203

if you want to split each file one-by-one.

Or you could use the Insert > Split Marker + Edit > Split at Markers method.

In the end, your EPUB should look something like this:

Mbp has to do with Mobipocket. Where did the HTML come from that has Mobipocket code in it?
