class LibXML::XML::Document
The XML::Document
class provides a tree based API for working with xml documents. You may directly create a document and manipulate it, or create a document from a data source by using an XML::Parser
object.
To read a document from a file:
doc = XML::Document.file('my_file')
To use a parser to read a document:
parser = XML::Parser.file('my_file') doc = parser.parse
To create a document from scratch:
doc = XML::Document.new() doc.root = XML::Node.new('root_node') doc.root << XML::Node.new('elem1') doc.save(filename, :indent => true, :encoding => XML::Encoding::UTF_8)
To write a document to a file:
doc = XML::Document.new() doc.root = XML::Node.new('root_node') root = doc.root root << elem1 = XML::Node.new('elem1') elem1['attr1'] = 'val1' elem1['attr2'] = 'val2' root << elem2 = XML::Node.new('elem2') elem2['attr1'] = 'val1' elem2['attr2'] = 'val2' root << elem3 = XML::Node.new('elem3') elem3 << elem4 = XML::Node.new('elem4') elem3 << elem5 = XML::Node.new('elem5') elem5 << elem6 = XML::Node.new('elem6') elem6 << 'Content for element 6' elem3['attr'] = 'baz' doc.save(filename, :indent => true, :encoding => XML::Encoding::UTF_8)

# File lib/libxml/document.rb, line 122 def find(xpath, nslist = nil) self.context(nslist).find(xpath) end
Return the nodes matching the specified xpath expression, optionally using the specified namespace. For more information about working with namespaces, please refer to the XML::XPath
documentation.
Parameters:
-
xpath - The xpath expression as a string
-
namespaces - An optional list of namespaces (see
XML::XPath
for information).
document.find('/foo', 'xlink:http://www.w3.org/1999/xlink')
IMPORTANT - The returned XML::Node::Set must be freed before its associated document. In a running Ruby program this will happen automatically via Ruby’s mark and sweep garbage collector. However, if the program exits, Ruby does not guarantee the order in which objects are freed (see blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/17700). As a result, the associated document may be freed before the node list, which will cause a segmentation fault. To avoid this, use the following (non-ruby like) coding style:
nodes = doc.find('/header') nodes.each do |node| ... do stuff ... end
# nodes = nil # GC.start
Source
# File lib/libxml/document.rb, line 129 def find_first(xpath, nslist = nil) find(xpath, nslist).first end
Return the first node matching the specified xpath expression. For more information, please refer to the documentation for XML::Document#find
.

Creates a copy of the node that can be inserted into the current document.
IMPORTANT - The returned node MUST be inserted into the document. This is because the returned node refereces internal LibXML
data structures owned by the document. Therefore, if the document is is freed before the the node is freed a segmentation fault will occur.
