Greetings, folks -
In an idle moment, I pasted this snippet of example code
from the factorcode.org page, just for fun:
USING: io kernel sequences
http.client xml xml.data xml.traversal ;
"http://factorcode.org"; http-get nip string>xml
"a" deep-tags-named
[ "href" attr ] map
[ print ] each
! this breaks in string>xml w/ the error:
mismatched
line 105
column 0
open T{ name f "" "br" "http://www.w3.org/1999/xhtml"; }
close T{ name f "" "body" "http://www.w3.org/1999/xhtml"; }
Mismatched tags
Opening tag: <br>
Closing tag: </body>
! but closing <br> w/ </br> (as per XHTML ??):
USING: io kernel sequences
http.client xml xml.data xml.traversal
splitting ;
"http://factorcode.org"; http-get nip
"<br>" "<br> </br>" replace string>xml
"a" deep-tags-named
[ "href" attr ] map
[ print ] each
! ...succeeds
The entry for <br> in w3schools 'tags' reference
<http://www.w3schools.com/tags/tag_br.asp> reads:
"Definition and Usage
The <br> tag inserts a single line break.
The <br> tag is an empty tag which means that it has no end tag.
Differences Between HTML 4.01 and HTML5
NONE.
Differences Between HTML and XHTML
In HTML, the <br> tag has no end tag.
In XHTML, the <br> tag must be properly closed, like this: <br />."
However, inserting
"<br>" "<br> < />" replace string>xml
or
"<br>" "<br> </>" replace string>xml
still breaks in string>xml, but inserting
"<br>" "<br> </br>" replace string>xml
works fine for me.
Is this just a consequence of the Factor code running on my ancient
OS X 10.6.8 system (Snow Leopard lives!), or differences between
XHTML, HTML 4.01, and HTML5, or a wacky description at w3schools?
Can anyone enlighten me on this, regarding the usage of string>xml?
Much grass,
~cw
