How to return single string value of XPath expression?

Question

This is my HTML:

 
  
Description

        
                      

              相关标签:
       
      

Answer 1

string(/) will return the string value of the whole document.

---

Update: To return the four separate strings returned by this XPath,

.//h3[@class='description-area']/following-sibling::p//text()[count(preceding-sibling::br) >= 0]

as a single string, wrap the above XPath similarly in string():

string(.//h3[@class='description-area']/following-sibling::p//text()[count(preceding-sibling::br) >= 0])

---

Update 2: But the br and text() maneuvers aren't necessary. You can simply get the string value of the p:

string(.//h3[@class='description-area']/following-sibling::p)
