Is there a means of reading files in reverse? I just want to be able to read a file from the beginning and once I read a particular line, I start reading lines backward from there.
Now, I could toss everything into a string array, but the file I'll be reading is roughly 100MB. I don't want... (3 Replies)

Guys,
I am trying to find a way to achieve this. I need to print /usr/local/apche/htdocs only from the string /usr/local/apache/htdocs/file.php using the regex. The below did not work. I know a solution with normal cut, I need a way to do this with the awk regex.

Hi All,
I have a String str="Manish". I would like to reverse it.
I know the option to do this in bash is: echo "Manish" | rev
but I have seen an alternate solution somewhere, which states that:
str="Manish" echo $str | awk '{ for(i=length($0);i>=1;i--) printf("%s",substr($0,i,1));... (7 Replies)

Hello,
Can anyone explain for me in this script to reverse the string?
1) the "x=x" part, how it works?
$ echo welcome | awk '{ for(i=length;i!=0;i--)x=x substr($0,i,1);}END{print x}'
$ emoclew2) x seems to be an array at the END, but can it automatically print the whole array in awk?
Thanks... (8 Replies)

xml::libxml::nodelist
XML::LibXML::NodeList(3pm) User Contributed Perl Documentation XML::LibXML::NodeList(3pm)
NAME
XML::LibXML::NodeList - a list of XML document nodes
DESCRIPTION
An XML::LibXML::NodeList object contains an ordered list of nodes, as detailed by the W3C DOM documentation of Node Lists.
SYNOPSIS
my $results = $dom->findnodes('//somepath');
foreach my $context ($results->get_nodelist) {
my $newresults = $context->findnodes('./other/element');
...
}
API
new(@nodes)
You will almost never have to create a new NodeList object, as it is all done for you by XPath.
get_nodelist()
Returns a list of nodes, the contents of the node list, as a perl list.
string_value()
Returns the string-value of the first node in the list. See the XPath specification for what "string-value" means.
to_literal()
Returns the concatenation of all the string-values of all the nodes in the list.
get_node($pos)
Returns the node at $pos. The node position in XPath is based at 1, not 0.
size()
Returns the number of nodes in the NodeList.
pop()
Equivalent to perl's pop function.
push(@nodes)
Equivalent to perl's push function.
append($nodelist)
Given a nodelist, appends the list of nodes in $nodelist to the end of the current list.
shift()
Equivalent to perl's shift function.
unshift(@nodes)
Equivalent to perl's unshift function.
prepend($nodelist)
Given a nodelist, prepends the list of nodes in $nodelist to the front of the current list.
map($coderef)
Equivalent to perl's map function.
grep($coderef)
Equivalent to perl's grep function.
sort($coderef)
Equivalent to perl's sort function.
Caveat: Perl's magic $a and $b variables are not available in $coderef. Instead the two terms are passed to the coderef as arguments.
reverse()
Equivalent to perl's reverse function.
foreach($coderef)
Inspired by perl's foreach loop. Executes the coderef on each item in the list. Similar to "map", but instead of returning the list of
values returned by $coderef, returns the original NodeList.
reduce($coderef, $init)
Equivalent to List::Util's reduce function. $init is optional and provides an initial value for the reduction.
Caveat: Perl's magic $a and $b variables are not available in $coderef. Instead the two terms are passed to the coderef as arguments.
