Dear Expert,
From following exmplle of example.php which is easily to extract xml data from example.xlm file, it just
use getElementsByTagName('file') in order to get the image file name in example.xml (example.png).
But how I convert HTML web paga data into XML format, because I would like to extract HTML data
by PHP coding.
The problem-1 : Converting HTML to XMLformat
THe problem-2, I use other way, I directly extract HTML data using example.php program and replace example.xml by mywebpage.html, and using getElementsByTagName('SPAN') to extract SPAN tag data
which is "116.200" but finaly it shown out no any result and no any error. It seem the php code
could not find out where SPAN tag is.
Question-1 Could you help on this and give some code hit to extract the tag <Span class="neg_bold">.nodevalue ?

<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<span class="neg bold">116.200</span>
</body>
