I am trying to scrape recipe website: myrecipes.com to extract recipe
details to be stored in an Sqlite db in my recipe android application. So
far, I was able to obtain data regarding recipe ingredients, instructions,
servings, nutrients etc... I'm trying to obtain data relating to the time
it takes a recipe to be made. The issue is the not all recipes have the
same time info., some might include: Total time or prep time or cook time
but not always.
To deal with this I use the following code on the html snippet below:
# Recipe time
duration_nodes = sel.xpath('//div[@class = "panel-pane
pane-entity-field pane-node-field-recipe-time recipe-time"]/div[@class =
"pane-content"]/div[@class = "field-collection-container clearfix"]')
for duration_node in duration_nodes:
try:
path = duration_node.xpath('//div[@class = "panel-pane
pane-entity-field pane-node-field-recipe-time recipe-time"]/div[@class =
"pane-content"]/div/div[@class =
"field-recipe-time"]/div/div/span[1]/text()').extract()
if path == 'Prep: ':
recipe['prep_time'] = duration_node.xpath('//div[@class
= "field-recipe-time"]/div/div/span[2]/text()').extract()
elif path == 'Cook: ':
recipe['cook_time'] = duration_node.xpath('//div[@class
= "field-recipe-time"]/div/div/span[2]/text()').extract()
elif path == 'Total: ':
recipe['total_time'] =
duration_node.xpath('//div[@class =
"field-recipe-time"]/div/div/span[2]/text()').extract()
except:
continue
<div class="panel-pane pane-entity-field pane-node-field-recipe-time
recipe-time">
<h2 class="pane-title">Recipe Time</h2>
<div class="pane-content">
<div class="field-collection-container clearfix">
<div class="field-recipe-time">
<div class="field-collection-view clearfix view-mode-recipe-time">
<div class="recipe-time-info">
<span class="recipe-time-text">Prep: </span>
<span class="recipe-time-duration">25 Minutes</span>
</div>
</div> </div>
<div class="field-recipe-time">
<div class="field-collection-view clearfix view-mode-recipe-time
field-collection-view-final">
<div class="recipe-time-info">
<span class="recipe-time-text">Cook: </span>
<span class="recipe-time-duration">45 Minutes</span>
</div>
</div> </div>
</div> </div>
</div>
The full code is:

'panel-pane pane-entity-field pane-node-field-yield']/div[@class =
'pane-content']/div[@itemprop = 'yield']/div[@class =
'field-yield']/text(), ': ')").extract()
return recipe
When I run the code, the output does not register and I can't figure why. I
suspect the issue is with the if-else statements after testing. Any help
would be appreciated.
