XUPDATE(1p) User Contributed Perl Documentation XUPDATE(1p)NAME
xupdate - Process XUpdate commands over an XML document
SYNOPSIS
xupdate [options] <xupdate-file> <input-file>
Options:
-u | --usage print brief help on usage
-h | --help print documentation
-n | --namespace prefix=namespace-uri
associate a namespace with a prefix for use
in XPath selections in XUpdate file
(this option may occur several times)
-k | --keep-ws preserve whitespace in the XUpdate file
-s | --strip-ws strip ignorable whitespace from the input file
-V | --version print current version and revision
-i | --indent indent the output XML
-j | --extra-indent like -i, but also adds a leading and a trailing
linebreak to every text node.
but also put an extra newline after
every start-tag and before every end-tag
OPTIONS --usage Print a brief help message on usage and exits.
--help Prints the manual page and exits.
--namespace prefix=namespace-uri
Associate a namespace with a prefix. The prefix may be used in the XPath selections in the XUpdate file to address nodes of the
source document that belong to the given namespace. This is especially useful for mapping the default namespace to a prefix
because XPath by definition doesn't honour default namespaces. This option may occur several times.
--keep-ws
Preserves any whitespace in XUpdate file. The default behaviour is to remove all ignorable whitespace and any leading or trailing
whitespace in all XUpdate command elements in the XUpdate file.
--strip-ws
Remove "ignorable" whitespace from the input file. The default behaviour is to keep any whitespace unless the --extra-indent (-j)
option is used. Note that the whitespace being present or not may affect results returned by some XPath expressions (such as
/foo/bar/text()[2]).
--version
Print version and revision number of This program command and version number of XML::XUpdate library used.
--indent
Indent the resulting document on output.
--extra-indent
Indent the resulting document on output as --indent, but also add a leading and a trailing linebreak to every text node.
--debug Print some debugging information about commands being applied.
DESCRIPTION
This program will parse the given XUpdate file and the input file and print the input file updated accordingly. XUpdate file format is
described in XUpdate Working Draft from 2000-09-14 (http://www.xmldb.org/xupdate/xupdate-wd.html).

XML::LibXML::Pattern(3) User Contributed Perl Documentation XML::LibXML::Pattern(3)NAME
XML::LibXML::Pattern - XML::LibXML::Pattern - interface to libxml2 XPath patterns
SYNOPSIS
use XML::LibXML;
my $pattern = XML::LibXML::Pattern->new('/x:html/x:body//x:div', { 'x' => 'http://www.w3.org/1999/xhtml' });
# test a match on an XML::LibXML::Node $node
if ($pattern->matchesNode($node)) { ... }
# or on an XML::LibXML::Reader
if ($reader->matchesPattern($pattern)) { ... }
# or skip reading all nodes that do not match
print $reader->nodePath while $reader->nextPatternMatch($pattern);
$pattern = XML::LibXML::Pattern->new( pattern, { prefix => namespace_URI, ... } );
$bool = $pattern->matchesNode($node);
DESCRIPTION
This is a perl interface to libxml2's pattern matching support http://xmlsoft.org/html/libxml-pattern.html. This feature requires recent
versions of libxml2.
Patterns are a small subset of XPath language, which is limited to (disjunctions of) location paths involving the child and descendant axes
in abbreviated form as described by the extended BNF given below:
Selector ::= Path ( '|' Path )*
Path ::= ('.//' | '//' | '/' )? Step ( '/' Step )*
Step ::= '.' | NameTest
NameTest ::= QName | '*' | NCName ':' '*'
For readability, whitespace may be used in selector XPath expressions even though not explicitly allowed by the grammar: whitespace may be
freely added within patterns before or after any token, where
token ::= '.' | '/' | '//' | '|' | NameTest
Note that no predicates or attribute tests are allowed.
Patterns are particularly useful for stream parsing provided via the "XML::LibXML::Reader" interface.
new()
$pattern = XML::LibXML::Pattern->new( pattern, { prefix => namespace_URI, ... } );
The constructor of a pattern takes a pattern expression (as described by the BNF grammar above) and an optional HASH reference mapping
prefixes to namespace URIs. The method returns a compiled pattern object.
Note that if the document has a default namespace, it must still be given an prefix in order to be matched (as demanded by the XPath
1.0 specification). For example, to match an element "<a xmlns="http://foo.bar"</a>", one should use a pattern like this:
$pattern = XML::LibXML::Pattern->new( 'foo:a', { foo => 'http://foo.bar' });
matchesNode($node)
$bool = $pattern->matchesNode($node);
Given an XML::LibXML::Node object, returns a true value if the node is matched by the compiled pattern expression.
