Xpath to extract elements from nodes based on element condition

Question

I have an xml for extracting elements -

<?xml version="1.0"?>
<Carmodels>
  <Cars>
    <id>1223</id>
    <cartype>Sedan</cartype>
    <price>1000</price>
  </Cars>
  <Cars>
    <id>1234</id>
    <car>Sports</car>
    <price>2500</price>
  </Cars>
  <Cars>
    <id>1123</id>
    <car>Taxi</car>
    <price>9000</price>
  </Cars>
  <Cars>
   <id>1223</id>
    <car>Taxi</car>
    <price>1000</price>
   </Cars>
</Carmodels>

Now I would need to extract <price> tags from <cars> node where <car> = Taxi. I need only Xpath for extracting the price.

Sample output:

 9000
 1000

We need Xpath only to execute through Java.

Answer 1

Please try the following XPath expression. It converts the car tag value to lower case. So both Taxi and taxi are taken into account.

XPath

/Carmodels/Cars[lower-case(car)="taxi"]/price

Answer 2

XPath 1.0 expressions which supports the word taxi written with lowercase or uppercase characters:

//Cars[car[translate(.,"tT","tt")="taxi"]]/price
//car[translate(.,"tT","tt")="taxi"]/following-sibling::price

Output: 2 nodes

<price>9000</price>
<price>1000</price>
