Subject: [xsl] One-based indexes in XPath From: Justin Johansson <procode@xxxxxxxxxxx> Date: Wed, 21 May 2008 02:14:31 +0900 |
Trusting this question is relevant to the XSL List. Would someone please give me advice as to why "1-based" indexes are used in XPath, such as para[1] instead of para[0] for the first para item/element? Why does the spec for XPath (and its/XQuery operator/function library) go against the norm for modern programming languages in which zero is the base for array-like collections? The reason for my question is to do with reconciling XPath and XSLT with an implementation in Javascript in which zero is the base index for arrays. My users may well be perplexed by having to decide whether an index number is in XPath/XSLT-world or Javascript-world. Thanks for comments, Justin Johansson
