# XML::LibXML::NodeList(3pm)

a list of XML document nodes

## 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.

### to\_literal\_delimited($separator)

Returns the concatenation of all the string-values of all the nodes in the list, delimited by the specified separator.

### to\_literal\_list()

Returns all the string-values of all the nodes in the list as a perl 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.
