python - how to make a selection for the dictionary? -


help please write xpath-expression.

html:

<div class="tabitem">     <p><strong>product composition</strong></p>     <p>93% polyamide 7% elastane</p>     <p>lining: 100% polyester</p><p>dress length: 90 cm</p>      <p><strong>product attributes;</strong></p>     <p>: boat neck, long sleeve, midi, zip, concealed, laced, side</p>     <p>lining type: full lining</p> </div>

this need following html dictionary:

data['product composition'] = '93% polyamide 7% elastane lining: 100% polyester</p><p>dress length: 90 cm' data['product attributes;'] = ': boat neck, long sleeve, midi, zip, concealed, laced, side lining type: full lining'

it important number of elements can vary. ie need universal solution

get every strong tag inside p, it's parent , next parent's siblings until there p tag strong tag inside or no more siblings left:

from lxml.html import fromstring   html_data = """<div class="tabitem">     <p><strong>product composition</strong></p>     <p>93% polyamide 7% elastane</p>     <p>lining: 100% polyester</p><p>dress length: 90 cm</p>      <p><strong>product attributes;</strong></p>     <p>: boat neck, long sleeve, midi, zip, concealed, laced, side</p>     <p>lining type: full lining</p> </div>"""  tree = fromstring(html_data) data = {} strong in tree.xpath('//p/strong'):     parent = strong.getparent()      description = []     next_p = parent.getnext()     while next_p not none , not next_p.xpath('.//strong'):         description.append(next_p.text)         next_p = next_p.getnext()      data[strong.text] = " ".join(description)  print data

prints:

{'product composition': '93% polyamide 7% elastane lining: 100% polyester',   'product attributes;': ': boat neck, long sleeve, midi, zip, concealed, laced, side lining type: full lining'}
