Conclusion of HTML analysis results in a cycle-deadlines
The line with the HTML code is given:
<td valign="top">First</td><td width="580" valign="top">The second</td><td>The third</td>
Print the text of all the elements in the loop td, which have the property valign equally top.
In [ ]:
txt = """<td valign="top">Первый</td><td width="580" valign="top">Второй</td><td>Третий</td>"""
doc = parsehtml(txt)
html = root(doc)
xpath = "//td[@valign=\"top\"]"
for el in findall(xpath, html)
print(el)
end
