Error Parsing attribute name

[wellesradio]

I can't open an ebook because every section brings up a warning:
"This page contains the following errors:
error on line 11 at column 312: error parsing attribute name"

The above-mentioned "line 11" is a doozy. I'll post an excerpt first so we can see "Column 312". "312" is apparently where the semicolon is at the end of this excerpt:

<script type="text/javascript">window.NREUM||(NREUM={}),__nr_require= function(e,n,t){function r(t){if(!n[t]){var o=n[t]={exports:{}};e[t][0].call(o.exports,function(n){var o=e[t][1][n];return r(o||n)},o,o.exports)}return n[t].exports}if("function"==typeof __nr_require)return __nr_require;for(var o=0;o<t.length;

The entirety of "Line 11" is as follows:

PHP Code:

Can anybody help me clarify this gobbledygook? Sigil wasn't able to do it automatically.
Thank you.

You need to use CDATA tags to handle the '<' and '>' symbols all throughout your script. They are not allowed in a script tag embedded in an xhtml tag. Alternatively, extract that script into its own javascript .js file, add it to the ebook and use a link tag to pull it in.

For example, the "<t.length;" is being treated like it is the start of a tag and the ; as an attribute.

Where on earth did you get this pile of crap from? It looks like a bad html website pulled into a book. The rules of parsing xhtml are much stricter than those used in html where that crap may fly.

So either wrap your javascript entirely in a CDATA tag or move it out into its own .js file.

[KevinH]

Also you will need to make sure this is a epub3 as epub2 does not support javascript at all. If it were me I would delete the entire script tag as it refers to browser engines and not ebook reader engines and is basically crap that no one wants in a epub.

It in fact looks like page load timing analytics crap. And refers to license keys. It even reaches out to a website: bam.nr-data.net

See: https://discuss.newrelic.com/t/relic...nitoring/42055

So it is analytics crap which does not belong in a an epub at all.

Rip it out is my best advice.

Thanks!
You're right. It was an old out of print book I found online on boats. Have no idea what they were trying to do there. Every page has a couple of these lines. When I delete them the page returns to normal like in a fairy tale.

Is there a way to delete an entire line using the find and replace feature? I know how to do that for single words or commands. I want to set it to search and delete any line with "script" in it.

[KevinH]

You can use Regular Expression Find and Replace if you understand regular expression syntax to do just that or there may be a plugin like Tag Mechanic that can delete tags.

[KevinH]

I Find and replace enable regular expressions.

If there is only one script tag in each file, using something along the lines of:

Find:
<script>.*</script>

And leave Replace empty

Should do it, but save a copy of the epub first in case something goes wrong.

If there is more than one script tag per file, you may have to limit the greediness of the match to prevent anything inbetween the two script tags from being deleted.
