No declaration found for element 'list-holder'

[kakkalla]

Hi everyone.

I open my epub that I have generated from InDesign in Sigil and I use the validation button to check it. I get a report that there are no problems. This checks with another program I use on my Mac named ePubChecker.

Now, I run a search and replace using Regex and I create an element named "list-holder" which I am using as a wrapper to help me style some list elements.

When I run the validator again, I get three errors:
1. Attribute 'class' is not declared for element 'list-holder'
2. No declaration found for element 'list-holder'
3. Element 'list-holder' is not allowed for content model (and then a series of tags that are valid)

What gives? Are we not able to use any tag we want in the code? How can I define my element 'list-holder' so that it does not cause these errors?

Thanks in advance.

You'll need to show us your code, both the stylesheet where you define the element and some content where you use it.

This is a typical entry exported from InDesign:

<p class="list1-box">
<span class="list1-box">C.	</span>
The binge eating and inappropriate compensatory 
behaviors both occur, on average, at least twice a week for 3 months.</p>

Using Regex, I convert all such entries into this:

<list-holder class="list1-box">
<list1-box-text><span class="list1-box">C.	</span>
</list1-box-text>
<pp class="list1-box">The binge eating and inappropriate compensatory behaviors both occur, on average, at least twice a week for 3 months.</pp></list-holder>

Here is the CSS for these elements:

list-holder.list1-ref-sa, list-holder.list1-ref, list-holder.list1-ref-sb{
	display:block;
	width:auto;
	height:auto;
	margin-top:0;
	margin-bottom:3px;
	background:none;
}
list-holder.list1-ref-sa{
	margin-top:6.5pt;
}
list-holder.list1-ref-sb{
	margin-bottom:6.5pt;
}
list1-ref-text{
	-epub-hyphens:none;
	-webkit-hyphens:none;
	font-size:0.833em;
	line-height:1.3;
	float:left;
	width:1em;
	background:none;
}
pp.list1-ref-sa, pp.list1-ref, pp.list1-ref-sb {
	-epub-hyphens:none;
	-webkit-hyphens:none;
	font-family:"Palatino-Roman", serif;
	font-size:0.833em;
	line-height:1.3;
	display:block;
	margin-left:1.75em;
	text-align:left;
	margin-right:3pt;
	background:none;
}

The strange thing is that when I load the epub onto my iPad via Book Proofer, the epub works flawlessly. I don't understand what's going on.

I look forward to your reply, and thanks for taking the time to help me.

The simple answer is you can't create your own tags. What made you think you could?

OK, thanks for the reply.

I thought I could because I normally work in XML.

Thanks again.
