XPath: select text node

📜 Title: Mastering XPath: Selecting Text Nodes like a Pro! 😎🔍

👋 Hey there, XML enthusiasts! 👨‍💻

Are you struggling to select specific text nodes from your XML using XPath? 🤔 Look no further, because we've got you covered! In this blog post, we'll dive into common issues and provide you with easy solutions to select either the first or the second text node in XPath. 🎉

Ready to become an XPath pro? Let's go! 🚀

The Dilemma 🤷‍♂️

Consider this scenario: you have the following XML structure:

<node>Text1<subnode/>text2</node>

And you want to select either the first or the second text node using XPath. But, uh-oh, selecting the text node directly doesn't seem to give you the expected result! 😬

The Wrong Path: /node/text()[2] ❌

At first glance, you might think that the XPath expression /node/text()[2] would do the trick. Unfortunately, this will not work as expected. Why? 🤔

Well, it's because the expression /node/text()[2] selects all text nodes inside the <node> element, and then returns the second node from that result. In our case, it would give you both "Text1" and "text2". Not what we wanted, right? 😔

The Solution: Selecting by Position 👈✅

To select the specific text node you desire, you have to leverage XPath's powerful indexing capabilities. Let's break it down step by step! 😉

Solution #1: Selecting the First Text Node

To select the first text node, you can use the expression /node/text()[position() = 1]. This will give you exactly what you need: "Text1". Hurray! 🎉

Solution #2: Selecting the Second Text Node

For selecting the second text node, you can adjust the previous expression slightly. Use /node/text()[position() = 2], and voila! You now get "text2". Awesome! 👏
