How to Check if a String Ends with a Value from an Array in XSLT 2.0

In the world of XML and XSLT (Extensible Stylesheet Language Transformations), string manipulation is a critical skill. Developers often face challenges while working with strings, especially when it comes to determining if a string ends with a specific value found within an array. If you’re asking the question: How can I detect that a string ends with a value from a pre-determined array?, you've come to the right place. In this article, we’ll break down the solution to this problem using XSLT 2.0.

Understanding the Requirement

When you need to check if a string ends with any of a set of predefined values (like suffixes), it can be particularly tricky. Unlike a complete match, where you look for exact equality, this situation demands flexibility in comparison. For example, if you have a string "книга" (meaning "book" in Russian), you might want to know if it ends with any of the Russian suffixes like "изм", "ия", "ист", etc.

Step-by-Step Solution

Here’s a straightforward way to accomplish this using XSLT 2.0. Assume you have the following variables defined in your template:

The string you want to check, say word.

An array of potential suffixes called obviouslyRussianSuffixes.

Step 1: Define Your Variables

You first need to set up your variables that will hold the string and the array of suffixes.

Step 2: Implement the Check with some

To check if the string ends with any of the suffixes in your array, you would use the some keyword coupled with the satisfies statement. This allows you to verify if at least one condition in your array is true.

Here’s how you would set that up in your xsl:if statement:

Explanation of the Code

some $suffix in $obviouslyRussianSuffixes: This part iterates through each item in the obviouslyRussianSuffixes array.

satisfies ends-with($word, $suffix): Checks if the current suffix is at the end of the word.

If the condition is true, it will output the value of word followed by a newline character.

Conclusion

By using the some ... satisfies structure, you can efficiently check if a string ends with any value from a specified array in XSLT 2.0. This approach not only simplifies string handling but also enhances the flexibility of your XML transformations. As you continue to work with XSLT, mastering these string manipulation techniques will significantly improve your coding efficacy and your projects overall.

Final Thoughts

Working with strings in XML might seem daunting at first, but with the right tools and methods, you can handle even complex logic effortlessly. Remember to keep practicing different scenarios to fully harness the power of XSLT 2.0 in your projects.
