Thank you. I've been experimenting to see how things behave with
what you call erroneous tags, and I have a question.
Could you give me some guidance as to how I should understand
the following behavior?
I have the following html file, test.html:
<!-- <body> -->
<!-- <badtag> -->
<!-- <badmatch> -->
<h1>heading</h1>
<p>paragraph</p>
<!-- </matchbad> -->
<!-- </badtag> -->
<!-- </body> -->
I have a simple Wt application that loads the contents of test.html
into a WText, and also links to test.html:
new WText ("link to <a href='links/test.html'>test</a>");
I have four cases: test.html, as given above; uncommenting the
<body> tag pair; uncommenting the <badtag> pair; and uncommenting
the <badmatch> pair.
In all four cases, when I navigate to test.html thro ugh the link, "heading"
and "paragraph" are displayed as I would expect.
In the WText, the original and <badtag> cases display the same as the
link. In the <body> case, the WText (or at least its contents) doesn't
display at all, and in the <badmatch> case, the raw contents of test.html
is displayed -- that is, no formatting, and the comments and markup
tags are displayed.
I'm just wondering how I should model the processing in my mind in
order to understand this behavior in detail. For example <badtag>
seems to be ignored, but <body> causes the contents not to be
displayed, while <badmatch> seems to turn off the html parsing.
(I get the same results with all three of recent versions of chrome,
opera, and ie.)
I should note that there is nothing urgent or problematic about this.
I'm just trying to learn the details of what is going on.
(Also, am I right that to be fully well-formed for a free-standing web
page, the html file should have html, head, and body tags, while
these are technically not legal in an html fragment in a WText?)
