Hi there. Was wondering if anyone could help me on this (hopefully straightforward) question: I have a test function that accepts an element parameter, and attempts to use DOM to find all child anchor elements below this node, and then find the class attribute for each anchor. The code should...

If this is a really simple application, then you could read the XML directly from your JSP using JSTL XML tags. http://java.sun.com/products/jsp/jstl/ For anything more complicated, you should really use the MVC design pattern. Have a JavaBean class to model your XML, and have the JSP access...

The char '.' is a literal '.' The string "." is evaluated as a regular expression in the replace call. To escape this, try using "\\." instead. The first '\' escapes the second '\', so that the character sequence passed to the regular expression engine is '\' '.' This then ensures the period...

How about: Java 5.0: http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/xpath/package-summary.html Or Xalan: http://xml.apache.org/xalan-j/apidocs/org/apache/xpath/package-summary.html Cheers, Neil

$string = "Foo\nFoo2"; $string =~ s/\n//g; Cheers, Neil

chomp ? $string = "foo\n"; chomp($string); Cheers, Neil

This is an example of Widening Primitive Conversion

Or perhaps: grep -n . test.txt | sort -nr | cut -d: -f 2 ;-)

Its on my Sun box. Ah, oops, was in a set of GNU utilities we installed. Oh well ;-)

IMHO the easiest way: man tac :-)

A minor variation on Dinesh's (19decsat) answer using a sub for clarity: foreach (sort byVal keys %hash) { print "$_ $hash{$_}\n"; } sub byVal { return $hash{$b} <=> $hash{$a}; } Cheers, Neil

Perhaps this article may help? http://www.bmsi.com/java/posix/package.html

Here's a modified version of the regexp which should work: #!/usr/bin/perl -w while (<DATA>) { if (/^ # start of line \s # a single whitespace ( # start grouping [0-9]+ # 1 or more digits \s+ # 1 or more whitespace...

Its quite useful to use the 'x' modifier to explain complex regular expressions: while (<DATA>) { if (/^ # start of line \s # a single whitespace ( # start grouping [0-9]{1,} # 1 or more digits \s{5} # exactly 5 spaces )...

Alternatively, if you intend all instances of your beans to share initialisation strings, then you can have: public class MyBean { private static String initValue; public static void setInitValue(String value) { initValue = value; } } Then, create and register a...

Assuming you have a context parameter defined as: <context-param> <param-name>foo</param-name> <param-value>bar</param-value> </context-param> And assuming you have a simple class like: package beans; public class TestBean { private String name; public String...

Here's one way using perl. #!/usr/bin/perl -w $file = shift; $file1 = "${file}1"; $file2 = "${file}2"; open FILE, $file or die; open FILE1, ">$file1" or die; open FILE2, ">$file2" or die; while (<FILE>) { # determine destination select substr($_, 44, 3) eq "002" ? *FILE2 : *FILE1...

Note that the second example has removed the "!". So instead of "! -mtime -1", it is "-mtime +7" Cheers, Neil

Oops, instead of "! -mtime -1" I think you can use "-mtime +7" Cheers, Neil
