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

XML::LibXML::XPathExpression - interface to libxml2 pre-compiled XPath expressions

## NAME

XML::LibXML::XPathExpression - XML::LibXML::XPathExpression - interface to libxml2 pre-compiled XPath expressions

## SYNOPSIS

```
  use XML::LibXML;
  my $compiled_xpath = XML::LibXML::XPathExpression->new('//foo[@bar="baz"][position()<4]');
  # interface from XML::LibXML::Node
  my $result = $node->find($compiled_xpath);
  my @nodes = $node->findnodes($compiled_xpath);
  my $value = $node->findvalue($compiled_xpath);
  # interface from XML::LibXML::XPathContext
  my $result = $xpc->find($compiled_xpath,$node);
  my @nodes = $xpc->findnodes($compiled_xpath,$node);
  my $value = $xpc->findvalue($compiled_xpath,$node);
  $compiled = XML::LibXML::XPathExpression->new( xpath_string );
```

## DESCRIPTION

This is a perl interface to libxml2's pre-compiled XPath expressions. Pre-compiling an XPath expression can give in some performance benefit if the same XPath query is evaluated many times. `"XML::LibXML::XPathExpression"` objects can be passed to all `"find..."` functions `"XML::LibXML"` that expect an XPath expression.

- **new()**

  ```
    $compiled = XML::LibXML::XPathExpression->new( xpath_string );
  ```

  The constructor takes an XPath 1.0 expression as a string and returns an object representing the pre-compiled expressions (the actual data structure is internal to libxml2).
