Subject [jira] [Commented] (TIKA-650) Missing required alt attribute on img tag
Date Sun, 01 May 2011 17:39:03 GMT

    [ https://issues.apache.org/jira/browse/TIKA-650?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13027481#comment-13027481

Raimund Merkert commented on TIKA-650:

I know, but it's a required attribute. So I would just make an empty attribute.

Personally, I can always work around this my having my own content handler inject an alt attribute
for img tags. But generally speaking, this sort of behavior needs to be documented at the
very least. I don't know if there are any other tags where required attributes are not provided

> I've written a content handler that prints out the xhtml tags for conversion from a word
document with embedded images. For images, it does not generate the "alt" attribute for img
tags, which causes validation to fail. alt is a required attribute in XHTML.
> Here's a partial output from [http://validator.w3.org/check]:
> {quote}
> Error Line 3, Column 1026: required attribute "alt" not specified
> ...meta><title> </title></head><body><p><img src="embedded:image63.jpg"></img></p>

> The attribute given above is required for an element that you've used, but you have omitted
it. For instance, in most HTML and XHTML document types the "type" attribute is required on
the "script" element and the "alt" attribute is required for the "img" element.
> Typical values for type are type="text/css" for <style> and type="text/javascript"
for <script>.
