There's a limit to the number of characters a bookmarklet can contain. Browser Max chars Netscape > 2000 Firefox > 2000 Opera > 2000 IE 4 2084 IE 5 2084 IE 6 508 IE 6 SP 2 488 IE 7 ~2084 IE 8 ~2200-2300 I tried it in the IE6 browser. The following code (573 characters) doesn't work as a bookmarklet. However, <a href="alert('Hi');">Short Bookmarklet</a> works. Actually, you don't have to save the link as a bookmark in order to test, just click the link, nothing happens if the length limit is exceeded.

Following are some bugs in the Xalan jar shipped with JBoss 5.1.0 GA and JBoss 6.0. The Xalan jar file is located in jboss-5.1.0.GA/lib/endorsed ( %JBOSS_HOME%/common/lib for JBoss 6.0). Test xml:
<?xml version="1.0" encoding="ISO-8859-1"?> ...Test xsl:
<?xml version="1.0" encoding="ISO-8859-1"?> <xs...XSLT Java code:
import org.w3c.dom.*; import javax.xml.parsers....DateUtil.java
import java.util.Date; public class DateUti...XSLT output:

XSLT by default writes namespace declarations in the output. Most of the time it's spurious, sometimes outright wrong. Take this XML:
<?xml version="1.0" encoding="ISO-8859-1"?> <ev...And this XSL:
<?xml version="1.0" encoding="ISO-8859-1"?> <xs...where DateUtil.java is:
import java.util.Date; public class DateUti...The output is (with JDK1.6):
Title: <br xmlns:java="http://xml.apache.org/x...The namespace declaration went to the <br> element, not the timestamp where it belongs. To remove the namespace info, add exclude-result-prefixes to the XSL:

The tags XML flow control tags are exactly the same as their Core flow control equivalents, except that the test condition with a boolean EL expression is replaced by the select condition with an XPath expression. In the case of the forEach tag, the items attribute is replaced with the select attribute. In a test condition, the XPath expression is evaluated to a boolean value by the rules of the XPath boolean() function, which converts its argument to a boolean as follows: a number is true if and only if it is neither positive or negative zero nor NaN. a node-set is true if and only if it is non-empty. a string is true if and only if its length is non-zero. an object of...
