去除jsp页面中丑陋的大断换行

Since my last post on trimming whitespace in JSPs seems to be a popular topic, I figured it appropriate to note that JSP 2.1 supports a new trimWhitespace directive. If you're using a Servlet 2.5 XSD, you can also do this in your web.xml: <jsp-config><jsp-property-group><url-pattern>*.jsp</url-pattern><trim-directive-whitespaces>true</trim-directive-whitespaces></jsp-property-group></jsp-config> A Servlet 2.5 XSD seems to be the following: <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" metadata-complete="false" version="2.5"> To learn more about this feature, view Summary of New Features in JSP 2.1 Technology and search for "TrimWhiteSpace". It'd be nice if there was anchors in this article for a direct link, but I couldn't find any. Now I just wish JSP's EL had an xmlEscape="true" flag to escape XML in printed variables. Freemarker supports this. Hat tip to Kerem and Krishna's Unified Expression Language for JSP and JSF article.</web-app>
