Subject: Re: [xsl] Question on space normalization in serialization From: "Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Tue, 1 Sep 2015 22:26:31 -0000 |
As it happens Ibve been experimenting over the last couple of days (encouraged by friends at oXygen) with bypassing the XML parserbs attribute-value normalization when applied to stylesheets, so that the XPath expression as parsed is the expression as written, enabling more accurate diagnostics especially with long multi-line XPath expressions. The trouble is it breaks edge cases where people really want those newlines in string literals turned into spaces. Or rather, where they wrote test cases that break if you change this.
