Hi I use PHP to extract a number from a website by XPath. I realized that there is a problem with extraction of data from such an HTML code:

XML

<html xmlns="http://www.w3.org/1999/xhtml">
the inside content...
</html>

and i use such xpath query:

/html/text()

it does not recognize the inside content unless i remove xmlns part from the HTML tag.
i want to fetch a number from this website:
http://www.sarafideniz.com/
which has such an XPath:

/html/body/div/div[4]/div/div/div/div/div/div/div/div/div/div/div/div/table/tbody/tr/td[3]/span/strong/text()

and there is a similar problem.
I used this website to check the xpath and I am sure that my PHP code has no problem.
is there anybody that can helpl?

thanks in advance
