I am working working with very large XML files (100s of MBs). The tree is fairly simple <items> <item> <column1>ABC</column1> <column2>DEF</column2> </item> <item> <column1>GHI</column1> <column2>KLM</column2> </item> </items> I need to parse this document, and remove some <item> elements. So far, the best peer...

I have an XML document (generated by Adobe XFA forms), that contains data like the following: <Position> <PositionBorder> <Title/> <StartDate/> <EndDate/> </PositionBorder> </Position> Since this file is defined elsewhere, I am not at liberty to change the format of the XML that I get.

An example of the line in the txt file is: [PATH] = "/this/directory/run.exe" Now I understand how to open the file for reading and writing in VB, but I need to parse out the path in the "" (quotation marks). Any help would be greatly appreciated!! --Adam ...
I'm trying to create a parser for a simple language with the lemon port to PHP, and it works, almost. The following grammar: %name SP_ %declare_class { class SpecParser } %token_prefix SP_ %include_class { public $retvalue = '<todo: error handling>'; public function singleKey($elem) { end($elem); return key($elem); } } %pa...
This has been something that's been bothering me for a while. How does one go about parsing the following text into the HTML below using ANTLR? I can't seem to wrap my head around this at all. Any Ideas? Markdown: > first line > second line > blockquote> <p>first line second line</p> <blockquote> <p>nested quote</p> </b...
Initially I was thinking to use SSIS to parse an EDI file, however I've seen a few manual EDI parsers (field mapping), and would like to use automate this functionality in C#. EDI file - ie: http://www.altova.com/images/shots/edi_source3.gif Tips appreciated. Thanks. ...
Exactly as the title asks: How would I remove all unnecessary spaces between single quotes skipping escaped quotes in PHP? I am looking for a fast implementation to pre-prep for parsing. I would prefer not to use regex if it would be slower than using a simple loop. (The double quotes below are for display purposes only) examples wo...

Hello folks, I'm having a bit of trouble manually emitting a token with a lexer rule in ANTLR. I know that the emit() function needs to be used but there seems to be a distinct lack of documentation about this. Does anybody have a good example of how to do this? The ANTLR book gives a good example of how you need to do this to parse ...
Following hot on the heels of my question about how to read from a line in vb .net, I need to do the following: change the line in a text file [Path] = "c:\this\certain\path\" with this line [Path] = "c:\that\other\newer\path\" these paths will most certainly be different lengths, so I need to either replace what's in the quotes ...

Now I'm kind of facing problems because I want to extract that HTML page as a string from this XML message. Ok this is the XML message I'm parsing: <AmigoRequest> <From></Fr...
How can I use struct.unpack() or some other function available in Python to easily convert one byte variable to a Python integer? Right now, it is done in a rather lame way: file = open("telemetry.dat", "rb").read() magic = file[0] int(binascii.hexlify(magic), 16) Is there another? ...

This would be part of a reverse-engineering project. To determine and document what a shell script (ksh, bash, sh) does, it is comfortable, if you have information about what other programs/scripts it calls. How could one automate this task? Do you know any program or framework that can parse a shell script? This way for instance, I co...
I would like to read and write n bits from/to binary files. For example, read the next n bits into an integer or the next n bits to a char. I need the data to be bit aligned and not byte aligned. Are there C++ libraries that allow me to do that? When I use ostream/istream, I seem to be restricted to using byte aligned data. This is no...
