python - xpath query on id //*[@id="page"] returns two elements -


i'm trying scrap site ketabejam.ir i'm using python3.4.1 , parsing use lxml 3.4.1
way parsed lxml.html.fromstring method
when load document on interpreter , ask following query number of pages , can handle pagination:

s = doc.xpath("//*[@id='page']")

surprisingly result:

>>>len(s) == 2 true

i got address of element firebug's minimal xpath, when choose normal xpath , query run smoothly
bug, or i'm doing wrong??

looking @ page source page linked, there 2 elements id in page. 1 of top of table, , other 1 of bottom of table.

the copy minimal xpath version of firebug works based on id of element. available elements have id tag , creates xpath in format -

//*[@id="elementid"]

which getting.

ideally, in every html page , there should 1 element particular id , id should unique across page. , seem firebug's minimal xpath depends on that.

in context, think both elements return same link, can use either continue scraping. or indicated , can use normal xpath that.
