If the raw is set for a text node, then to_s() will not entities will not normalize (turn into entities) entity values. If you want to write out other nodes with a particular encoding, you must wrap your output object with Output: Encoded Output e = Element.new "" e.text = "f\xfcr" # ISO-8859-1 The processed entities are &, <, >, ", and '. ruby xml-parsing rexml share|improve this question edited Dec 13 '12 at 17:03 the Tin Man 110k22137206 asked Dec 13 '12 at 15:48 Emil Petkov 1151212 add a comment| 2 Answers 2 http://optimisersonpc.com/error-cannot/install-ruby-gems.html

If you wish to post a correction of the docs, please do so, but also file bug report so that it can be corrected for the next release. Filtering for Events on Particular Elements with Procs parser.listen( :characters, %w{ changelog todo } ) {|text| puts text } parser.parse In this example, only the text content of changelog and todo In Ruby, both IO instances (File) and String instances support <<.

The argument specifies the source from which we want to read an XML document. Stream parsing is faster (about 1.5 times as fast). The entities in that node won't be processed, so you have to deal with entities yourself. This means that you'll have to deal with entities yourself: Entity Replacement doc = Document.new(' ]>replace &ent;',{:raw=>:all}) doc.root.text #-> "replace &ent;" doc.to_s # Generates: #

  1. I implemented the following: ...perform an HTTP GET request...
  2. How safe is 48V DC?
  3. This vulnerability has been assigned the CVE identifier CVE-2013-1821.
  4. encoding ||= xml_decl.encoding if encoding != 'UTF-8' && !output.kind_of?(Output) output = Output.new( output, encoding ) end formatter = if indent > -1 if transitive require "rexml/formatters/transitive" REXML::Formatters::Transitive.new( indent, ie_hack ) else
  5. There are a few caveats when using XPath, however: If you don't supply a namespace mapping, the default namespace mapping of the context element is used.
  6. By default the limit is set to 10240.
  7. There is a wrinkle: REXML will write what it gets in as long as you don't access the text.
  8. If there is a child and it is an DocType, then replace it.
  9. DocType @children[ insert_before_index ] = child else @children[ insert_before_index-1, 0 ] = child end else # Insert at end of list @children << child end child.parent = self else rv =
  10. You can also do the following require "rexml/document" include REXML # so that we don't have to prefix everything with REXML::...

The problem is that, if you can change the text in a node, REXML can never tell which tokens you want to have replaced with entities. Rexml::elements Accept Nth argument style and options Hash style as argument.

The code block will be executed then for each iteration. http://stackoverflow.com/questions/12888452/reading-xml-file-using-rexml-says-undefined Instead of the add_element method, you can also use the << method on Element.elements.

Who is this Voyager character? Rexml Gem REXML does not write one if one was not specified, because it adds unnecessary bandwidth to applications such as XML-RPC. Deprecated. Product of all divisors=cube of number.

Rexml Document New

Using namespaces source = "" doc = Document.new source doc.elements["/a/x:b"].attributes["id"] # -> '1' XPath.first(doc, "/a/m:b", {"m"=>"bar"}).attributes["id"] # -> '2' doc.elements["//x:b"].prefix # -> 'x' doc.elements["//x:b"].namespace # -> 'foo' http://ruby-doc.org/stdlib-2.3.0/libdoc/rexml/rdoc/REXML/Document.html This is because XPath itself counts elements from 1, and REXML maintains this relationship; IE, root.elements['*[1]'] == root.elements[1]. Ruby Rexml Example Two-headed version of \Rightarrow or \implies Draw a hollow square of # with given width Build me a Brick Wall! Rexml Xpath If you have questions about Ruby or the documentation, please post to one of the Ruby mailing lists.

Adding elements by hand is faster than the convenience method, but which you use will probably be a matter of aesthetics. I've tried to keep the API as intuitive as possible, and have followed the Ruby methodology for method naming and code flow, rather than mirroring the Java API. A controversial point is whether Document should always write the XML declaration () whether or not one is given by the user (or source document).

Simply pass an object that supports <<( String ) to the write method of any object. If it finds any of these entities in the document, it replaces them with their values: Entity Replacement doc = Document.new ' ]>&ent;' doc.root.text #-> "replace" more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed This is because REXML does lazy evaluation of entities.

Actually, root.elements[1] equals root.elements[*[1]], where *[1] is the XPath expression for the first child. Rexml Each Element Registration is free and takes only a minute. IOs are expected to be sources of valid XML documents. @param context if supplied, contains the context of the document; this should be a Hash. # File rexml/document.rb, line 36 def

In further examples, we will not include the require or parser construction lines, as they are the same for all of these examples.

By default the limit is set to 10240. What happens if only some of the words are also entity reference values? The event is identified by the symbol :characters. Rexml Parse So with root.attributes['id'] we get the value of the attribute id of the root element.

XMLDecl if @children[0].kind_of? Can I use that to take out what he owes me? Examples output = "" tr = Transitive.new tr.write(Document.new(""), output) output output an object which supports ‘<< string’; this is where the document will be written. If you want to insert an element between two elements, you can use either the standard Ruby array notation, or Parent.insert_before and Parent.insert_after.

DocType @children[ insert_before_index ] = child else @children[ insert_before_index-1, 0 ] = child end else # Insert at end of list @children << child end child.parent = self else rv = You will get better, faster, help that way. Can I cite email communication in my thesis/paper? The REXML::Element.texts method is what you are looking for: $ irb irb(main):001:0> require "rexml/document" => true irb(main):002:0> doc=REXML::Document.new("123 street
") => ... irb(main):003:0> doc.root.texts => ["123 street", "amstown", "amserland"]

Using to_a() all_elements = doc.elements.to_a all_children = doc.to_a all_upc_strings = doc.elements.to_a( "//item/attribute::upc" ) all_name_elements = doc.elements.to_a( "//name" ) Text Nodes REXML attempts to make the common case simple, but this means The two methods return the added element. This is how it goes with attributes: irb(main):033:0> doc2.root.delete_attribute('id') => ... irb(main):034:0> puts doc2 Bertrand Russell The Problems of Philosophy Oxford University Press Creating and Inserting Elements and Attributes Now we will create a small bibliography document, consisting of one biblioentry, from scratch.

Moreover, if you write one of these characters in a Text node or attribute, REXML converts them to their entity equivalent, e.g. & for &. In addition, with the method add_attribute, you can add an attribute to an existing element. If you want an XML declaration, the easiest way to add one is mydoc << Document::DECLARATION DEPRECATED Use: mydoc << REXML::XMLDecl.default Attributes entity_expansion_count[R] Public Class Methods entity_expansion_limit() click to toggle source Deprecated.

Would we find alien music meaningful? Feed your head. Once you have a document, you can access elements in that document in a number of ways: The Element class itself has each_element_with_attribute, a common way of accessing elements. Additionally, when REXML finds any of these entity references in a document source, it converts them to their character equivalents.

This writes out the entire XML document, including XML declarations, doctype declarations, and processing instructions (if any are given).

This API differs from SAX2 in a couple of ways, such as having more filters and multiple notification mechanisms, but the core API is SAX2.
