A) Introduction
I feel there is a parcing problem when HTML file has only plain text file between <body> and </body>.
I attached 3 test html files:
test-big.html(68KB)
test-fail.html(39KB)
test-ok.html(27K)
test-fail.html and test-ok.html has the following format. Only difference is their plain text file size between <body> and </body>:
<html><head><title>some title</title></head>
<body>
[Just plain text file]
</body>
</html>
test-big.html is much more big compare to the test-fail.html and test-ok.html ,and it has lots of html tags between <body> and </body>.
B) PROBLEM
I used the attached HtmlReader to read those 3 files. First of all I noticed ParagraphView can read test-big.html which is bigger that other two files.
Reading test-ok.html was fine while reading test-fail.html was failed:

The fact that decides fail or succeed in this format is the SIZE of plain text between <body> tags because:
if I add more plain text into test-ok.html(27KB) so that its size is about the size of test-fail.html(39KB) then test-ok.html is also failed. But I can't tell the maximum size that ParagraphView can display is about 27KB because even test-big.html(68KB) was fine to display. One interesting fact is 'parcing performance compare' as below.
test-big.html(68KB) : 25 sec to display
test-ok.html(27KB): over 45 sec to display
C) Summary
There is an inefficience in parcing html file that has plain text between body tags. As a result of this I got exceptions if the file size is bigger than around 27KB.
