What are the best practices for converting string values to decimal values in XSLT?

When converting string values to decimal values in XSLT, it is important to ensure that the string is in a valid numeric format before attempting the conversion. This can be done by using functions like number() or xs:decimal() in XSLT. It is also recommended to handle any potential errors or exceptions that may arise during the conversion process. ```xml <xsl:variable name="stringValue" select="'123.45'" /> <xsl:variable name="decimalValue" select="xs:decimal($stringValue)" /> ```
