Write a parser that accepts this language, evaluates the expressions it is
given and stores the results in the appropriate registers. Your main class
should be called Calculator. The program should be run from the command line:
> java Calculator
Then the calculator will wait for keyboard input. After a line of input has
been entered, the program will check whether it is |

发帖数: 2416 | 5 The popularity of xml has multiple reasons:
1. technology wise, xml itself is a nice piece of technology.
The key point is it keeps
the data presentation in a very simple way, so simple that any system
that supports string manipulation can implement an xml parser.
The great benefits of this is it allows hetrogeneous systems to talk to
each other in an easy way.
2. politics wise, xml is a few only things that are supported by
almost all big players in this industry. The industry can't afford

发帖数: 39 | 6 try javax.swing.text.rtf package.
RTF format is not complicated. Make sure what text you want to extract
and you can write a parser of your own easily I believe.
ALso search on Google.
If you can't find one or make one on your own, come back and perhaps
I'd try to write one for you.:-)

发帖数: 29 | 7 I am now trying to extend Java. In addition to lexer and parser,
I need one function that can inference the type of expression
for java. Or, better if it can give the type range during parsing.
No other requirement. Any guru know such tools?
I checked JavaCC, SableCC, and some other tools, But can not find
such capability. Is there any third implementation based on such
CC tools, such as a Compiler-Compiler based full java compiler (in
which there must be such functions)? I say CC-based because |

发帖数: 29 | 8 I'm not sure, but I think JavaCC has a visitor pattern where you can add
functions to each node on the parser tree.
I suggest you send a email to professor Jens p******[email protected], he's one
of the guys that knows more on this. |

I tried to use XML to parse a config file and it seemed take a

BTW, for AbstractAction, how to specify its name and icon (used
in menus and buttons) after its construction?

发帖数: 133 | 11 google了一下，发现java有DOM, 还有一种叫SAX的。据说DOM不好。
哪位大虾介绍一下吧，他们有什么区别呢？
如果我想用来parse一个巨大的xml的file, ~500MByte，
应该用哪一个？怎么用呢？
//bow
多谢！ |

st
发帖数: 1685 | 12 use SAX, which is single parse without building up the tree structure,
500M xml probably will bring DOM... (not enough memory)...
also, there are many many versions of DOM, SAX for java, check them
yourself. :D |
|
e***g
发帖数: 158 | 13 depends on what you want to do after parse. don't use SAX unless you
have to, it's more work. |
|

发帖数: 2277 | 14 or use JAXB to get flexibility of DOM and performance of SAX. |

发帖数: 158 | 15 is it mature/popular yet? haven't heard of it for a while.
well it may not fit, if he wants to search by xpath, or to modify xml.
there's is no THE solution, it depends on what he wants to do. |

w********c
发帖数: 2632 | 17 It's an issue of the context. SAX is used for simplicity and speed, while DOM
is used for flexibility. If ur source is scanned only once, which is true in
most massive data processing, SAX is good enuf. |

In general, if you are going to manipulate XML, you probably want to use DOM
so that you can insert/delete/update node in the DOM tree. If you are going
to parse XML only without any manipulation, you can use either DOM or SAX, but
SAX is faster comparing to DOM and uses less memory. In your case, you may
have to use SAX unless you have a lot memory.

发帖数: 1879 | 19 Not being able to compile greater than 64K byte code is really a problem
in certain applications. Mainly in the lexers and parsers where large
precomputed tables is stored and could easily exceed 64K. |

发帖数: 1879 | 21 This is exactly the problem that I am facing. Unless that I write my own
specific parser, there seemed to be no way to do it. Too bad, my program
needs to be run on Windows, SGI and Mac :(
Boy, it is a pain in the rear to write it. |

发帖数: 201 | 22 actually my question is about parsing.
you can get the line and column number from the parser,
but you can not use subString to get the corresponding strings
because if these are tabs, the column number is not exactly the
position of the character in the string
for example:
"\t\tx=int;"
the column for x could be 8 or 4. but you should use subString(3,4?) to get "x",
but not (8,.)or (4,.). |
|
j******r
发帖数: 201 | 23 yes
if you have a string "\t\tx", and the length of tab is 4, the parser
i am using (javacc) will tell me the column number of 'x' is 8, not 3.
And the editor will show the column is 8 too.
Anyway, if I want to read a file, and display it in another terminal.
And I want the display is exactly as it is in the original one, i still need
to know the length of each '\t'. |

发帖数: 2421 | 24 I think you question is that you want to make a 'generic' plot package

I am working on my project by letting the chart/plot package accept the
XML form of data. Basically most of my plot is 2D plot, then I just define
the data as

by letting this generic structure , you can write your parser to parse it

发帖数: 2421 | 27 okey, your xml file is not well formated for parsing. My suggestion is
that you can write a class to get rid of the all document head at the first
place and put all record well-formated [Cin one file(or stream).
Then what you need to do is just write a xslt to transform the
xml to whatever the format you want and parse it into your application. |

发帖数: 214 | 36 没有"save as(complete)"那么简单。
对程序来说一个网页URL就是文本，一个从80端口受到的数据流。IE懂得读这个文本, 认
识里面的图片,连接等才知道要去别的URL下载图片，他还要足够聪明的把每个图片的连接
改成指向下载后的本地图片。
如果你要写程序做这件事，你的程序要懂得去解析html，认出里面的图片下载之。还要会
修改html把图片的url该成本地。搜索java html parser可以找到一些工具。
图简单的话可以找IE的COM，用VB写桌面程序调用。

发帖数: 1879 | 37 I have a question regarding Jelly and other XUL or XAML tools on
error handling. Basically, how they do it.
1. how they handle parse errors. The errors are not syntactic ones
that XML parsers SAX/JDOM detect, but semantic ones like unknown
tags, invalid variables, invalid values, wrong attributes etc.
2. logging.
3. warning/debugging.
I am currently trying to come up a solution to improve CookXml
( cookxml.sourceforge.net )'s error handling, but it would be nice
to know how others doing |

发帖数: 1879 | 42 ft, there is no package, just an idea, since everything must be tightly

reading it. |

I know Eclipse/IntelliJ IDEA have the feature, I am wondering how

Any pointers? Thanks. |

Running the Standard Doclet Programmatically

which solved my problems. I can now get all the information within
the same JVM. Call JavaDoc multiple times as well... and suppress
warnings/errors.
What's so cool is that now I can write my own doclet for custom XML
parsers created using CookXml. The doclet generates a JavaDoc like
