"Keep the common case simple, and the + uncommon, possible."</p> + + <p>REXML avoids The DOM API, which violates the maxim of simplicity. It + does provide <em>a</em> DOM model, but one that is Ruby-ized. It is an + XML API oriented for Ruby programmers, not for XML programmers coming + from Java.</p> + + <p>Some of the common differences are that the Ruby API relies on block + enumerations, rather than iterators. For example, the Java code:</p> + + <example>for (Enumeration e=parent.getChildren(); e.hasMoreElements(); ) { + Element child = (Element)e.nextElement(); // Do something with child +}</example> + + <p>in Ruby becomes:</p> + + <example>parent.each_child{ |child| # Do something with child }</example> + + <p>Can't you feel the peace and contentment in this block of code?

So in comparing NQXML and REXML you can + look at four things: speed, size, completeness, and API.</p> + + <p><link href="benchmarks/index.html">Benchmarks</link></p> + + <p>REXML is faster than NQXML in some things, and slower than NQXML in a + couple of things. You can see this for yourself by running the supplied + benchmarks. Most of the places where REXML are slower are because of the + convenience methods<footnote>For example, + <code>element.elements[index]</code> isn't really an array operation; + index can be an Integer or an XPath, and this feature is relatively time + expensive.</footnote>. On the positive side, most of the convenience + methods can be bypassed if you know what you are doing. Check the <link + href="benchmarks/index.html"> benchmark comparison page</link> for a + <em>general</em> comparison. You can look at the benchmark code yourself + to decide how much salt to take with them.</p> + + <p>The sizes of the XML parsers are close<footnote>As measured with + <code>ruby -nle 'print unless /^\s*(#.*|)$/' *.rb | wc -l</code> + </footnote>. NQXML 1.1.3 has 1580 non-blank, non-comment lines of code; + REXML 2.0 has 2340<footnote>REXML started out with about 1200, but that + number has been steadily increasing as features are added. XPath + accounts for 541 lines of that code, so the core REXML has about 1800 + LOC.</footnote>.</p> + + <p>REXML is a conformant XML 1.0 parser. It supports multiple language + encodings, and internal processing uses the required UTF-8 and UTF-16 + encodings. It passes 100% of the Oasis non-validating tests. + Furthermore, it provides a full implementation of XPath, a SAX2 and a + PullParser API.</p> + </subsection> + + <subsection title="XPath"> + <p>As of release 2.0, XPath 1.0 is fully implemented.</p> + + <p>I fully expect bugs to crop up from time to time, so if you see any + bogus XPath results, please let me know. That said, since I'm now + following the XPath grammar and spec fairly closely, I suspect that you + won't be surprised by REXML's XPath very often, and it should become + rock solid fairly quickly.</p> + + <p>Check the "bugs" section for known problems; there are little bits of + XPath here and there that are not yet implemented, but I'll get to them + soon.</p> + + <p>Namespace support is rather odd, but it isn't my fault. I can only do + so much and still conform to the specs. In particular, XPath attempts to + help as much as possible. Therefore, in the trivial cases, you can pass + namespace prefixes to Element.elements[...] and so on -- in these cases, + XPath will use the namespace environment of the base element you're + starting your XPath search from. However, if you want to do something + more complex, like pass in your own namespace environment, you have to + use the XPath first(), each(), and match() methods. Also, default + namespaces <em>force</em> you to use the XPath methods, rather than the + convenience methods, because there is no way for XPath to know what the + mappings for the default namespaces should be.

Some malformed XML, especially XML that + contains literal '<' embedded in the document, causes REXML to hang. + REXML should be throwing an exception, but it doesn't; this is a bug. I'm + aware that it is an extremely annoying bug, and it is one I'm trying to + solve in a way that doesn't significantly reduce REXML's parsing + speed.</a> + + <q>I'm using the XPath '//foo' on an XML branch node X, and keep getting + all of the 'foo' elements in the entire document. Why? Shouldn't it return + only the 'foo' element descendants of X?</q> + + <a>No. XPath specifies that '/' returns the document root, regardless of + the context node. '//' also starts at the document root. If you want to + limit your search to a branch, you need to use the self:: axe. EG, + 'self::node()//foo', or the shorthand './/foo'.</a> + + <q>I want to parse a document both as a tree, and as a stream. Can I do + this?</q> + + <a>Yes, and no. There is no mechanism that directly supports this in + REXML. However, aside from writing your own traversal layer, there is a + way of doing this. To turn a tree into a stream, just turn the branch you + want to process as a stream back into a string, and re-parse it with your + preferred API. EG: pp = PullParser.new( some_element.to_s ). The other + direction is more difficult; you basically have to build a tree from the + events. REXML will have one of these builders, eventually, but it doesn't + currently exist.</a> + + <q>Why is Element.elements indexed off of '1' instead of '0'?</q> + + <a>Because of XPath. The XPath specification states that the index of the + first child node is '1'. Although it may be counter-intuitive to base + elements on 1, it is more undesireable to have element.elements[0] == + element.elements[ 'node()[1]' ]. Since I can't change the XPath + specification, the result is that Element.elements[1] is the first child + element.</a> + + <q>Why isn't REXML a validating parser?</q> + + <a>Because validating parsers must include code that parses and interprets + DTDs. I hate DTDs. REXML supports the barest minimum of DTD parsing, and + even that isn't complete. There is DTD parsing code in the works, but I + only work on it when I'm really, really bored. Rumor has it that a + contributor is working on a DTD parser for REXML; rest assured that any + such contribution will be included with REXML as soon as it is + available.</a> + + <q>I'm trying to create an ISO-8859-1 document, but when I add text to the + document it isn't being properly encoded.</q> + + <a>Regardless of what the encoding of your document is, when you add text + programmatically to a REXML document you <em>must</em> ensure that you are + only adding UTF-8 to the tree. In particular, you can't add ISO-8859-1 + encoded text that contains characters above 0x80 to REXML trees -- you + must convert it to UTF-8 before doing so. Luckily, this is easy: + <code>text.unpack('C*').pack('U*')</code> will do the trick. 7-bit ASCII + is identical to UTF-8, so you probably won't need to worry about this.</a> + + <q>How do I get the tag name of an Element?</q> + + <a>You take a look at the APIs, and notice that <code>Element</code> + includes <code>Namespace</code>. Then you click on the + <code>Namespace</code> link and look at the methods that + <code>Element</code> includes from <code>Namespace</code>. One of these is + <code>name()</code>. Another is <code>expanded_name()</code>. Yet another + is <code>prefix()</code>. Then, you email the author of rdoc and ask him + to extend rdoc so that it lists methods in the API that are included from + other files, so that you don't have to do all of that looking around for + your method.</a> + </faq> + + <credits> + <p>I've had help from a number of resources; if I haven't listed you here, + it means that I just haven't gotten around to adding you, or that I'm a + dork and have forgotten.
