XPath with multiple conditions

XPath with Multiple Conditions: A Handy Guide 👀

So, you have stumbled upon the fascinating world of XPath, but you're stuck on how to select nodes that satisfy multiple conditions? Fear not! We've got you covered with our easy solutions and hacks. By the end of this blog post, you'll be XPath ninja material! 🥷

The Question and the Struggle 🤔

The original question was: "What XPath can I use to select any category with a specified name attribute and any child node author with the given value?"

The XPath attempt made by the questioner was:

//quotes/category[@name='Sport' and author="James Small"]

But alas, it wasn't working! 😩 Let's dive into the code and find a fix together.

The XML Schema 📄

To better understand the problem, let's take a closer look at the XML structure we're dealing with:

<?xml version="1.0" encoding="utf-8"?>
<quotes>
  <category name="Sport">
    <author>
      James Small
      <quote date="09/02/1985">Quote One</quote>
      <quote date="11/02/1925">Quote nine</quote>
    </author>
  </category>
  <category name="Music">
    <author>
      Stephen Swann
      <quote date="04/08/1972">Quote eleven</quote>
    </author>
  </category>
</quotes>

Understanding the Problem 🕵️‍♀️

The attempted XPath had good intentions, but it lacked clarity and precision. The XPath was looking for a category with the name attribute "Sport" and an author node anywhere in the XML with the value "James Small." However, it missed an important detail – the author node is a child of the category node.

The Magical XPath Solution ✨

To select a category with a specified name attribute and an author child node with a given value, we need to tweak the XPath a bit. Here's the corrected version:

//category[@name='Sport']/author[.='James Small']

Let's break it down:

• //category[@name='Sport'] selects the category node with the name attribute 'Sport'

• /author[.='James Small'] narrows down to the author child node with the text content 'James Small'

By combining these two conditions, we achieve our desired result! 🎉
