The provided code snippet appears to be written in XSLT (eXtensible Stylesheet Language Transformation), which is a language used for transforming XML documents. It seems to be used within the context of SAP BTP (Business Technology Platform), which is a cloud-based platform offered by SAP.

The purpose of this code snippet is to perform a conditional replacement of the phone numbers based on the country. Let's break down the logic:

1. The code starts with the <xsl:value-of> element, which is used to output the result of an XSLT expression as a text value.
2. The expression begins with an if condition:

• $nodes_in/Country ='DE' checks if the value of the <Country> element in the input XML is equal to 'DE' (which likely represents Germany). If true, it proceeds to the "then" part of the condition; otherwise, it goes to the "else" part.

3. In both the "then" and "else" parts, the Replace() function is used to replace the phone numbers:

• $nodes_in/PhoneNumber represents the value of the <PhoneNumber> element in the input XML.
• The regular expression '(\d{1})(\d{3})(\d+)' captures and groups the phone number digits into three parts: the first digit, the next three digits, and the remaining digits.
• The replacement string '+49 $2 $3' replaces the matched phone number with '+49' (the country code for Germany) followed by a space, the second captured group (the three digits), another space, and the third captured group (the remaining digits).
• Therefore, the resulting replaced phone number will be in the format '+49 XXX XXXX' (e.g., '+49 123 4567').

It's worth noting that the "then" and "else" parts of the condition in the provided code snippet are identical, so the phone number replacement will be the same regardless of the country value.
