Empty results of xpath is not printing

postgraduatedegrees=tree.xpath('//*[@id="block-scholarly- 
      content"]/div/article/div/div/div//*[contains(text(),"Degree 
      of")]/text()')

      postgraduatedegreeslinks=tree.xpath('//*[@id="block-scholarly- 
      content"]/div/article/div/div/div//*[contains(text(),"Degree of")]/@href')

      Output:
       len(postgraduatedegrees)
       Out[222]: 52

      len(postgraduatedegreeslinks)
       Out[223]: 40

I have tried using string(.) and textContant()

postgraduatedegreeslinks=tree.xpath('//*[@id="block-scholarly- 
      content"]/div/article/div/div/div//*[contains(text(),"Degree of")][@href]/text()')

for p in postgraduatedegreeslinks
      print (p.extract)
