xpath with big files

[Vladimir Kropylev]

Hi,
I've encountered a problem when trying to use lxml.etree.xpath with
big (63Mb) file. It returns empty list on any request.
Is there any restriction on file size for lxml.etree.xpath?

This is what I do:

f=open(filename)
tree = etree.parse(f)
f.close()
r = tree.xpath('//image')
print(r)

it prints:
[]

What is wrong here?

No.

Consider using

tree = etree.parse(filename)

r = tree.xpath('//image')
print(r)

it prints:
[]

Does your document use namespaces? In that case, asking for an unnamespaced
"image" will not get you any result.
