  • How to read from an XmlReader without moving it forwards

    - by andy
    hey guys, I've got this scenario: while (reader.Read()) { if (reader.NodeType == XmlNodeType.Element && reader.Name == itemElementName) { XElement item = null; try { item = XElement.ReadFrom(reader) as XElement; } catch (XmlException ex) { //log line number and stuff from XmlException class } } } In the above loop I'm transforming a certain node (itemElementName) into an XElement. Some nodes will be good XML and will go into an XElement, however, some will not. In the CATCH, I'd like to now only catch the standard XmlException stuff... I'd also like to catch an extract of the current Xml and a string. However, if I do any kind of READ operation on the node before I pass it to the XElement, it moves the reader forward. How can get a "snapshot" of the contents of the OuterXml of the reader without interfering with it's position?

  • Modifying text files and executing programs with command line parameters in c# or c++ on Linux

    - by Robert Harvey
    I have a need to create a utility in Suze Linux. The utility will make modifications to some text files, and then use the information in those text files to program a device in the computer using a different executable which accepts command line parameters. I am fluent in c#, but have never worked with Linux. Should I take the time to learn Gnu C++ to do this, or install Mono? How would I execute the programming utility and pass it command line parameters?

  • Best tools to parse reports

    - by Andy Schaefer
    I have a report that I need to parse/scrape for loading into an alternate or query-able data store. The report looks like something akin to: this. My gut is that PERL would do a decent job, but I have several different permutations of the report and I don't really want to make a script around each form. This report is a pretty stock type report, and I have seen where Monarch Pro can parse these types of reports, but I have had a difficult time finding alternatives to how these could be parsed since I'm looking to do this working primarily in a Linux environment. Any suggestions?

  • Perl: How do I extract certain bits from a byte and then covert these bits to a hex value?

    - by Siegfried Hepp
    I need to extract certain bits of a byte and covert the extract bits back to a hex value. Example (the value of the byte is 0xD2) : 76543210 bit position 11010010 is 0xD2 Bit 0-3 defines the channel which is 0010b is 0x2 Bit 4-5 defines the controller which is 01b is 0x1 Bit 6-7 defines the port which is 11b is 0x3 I somehow need to get from the byte is 0xD2 to channel is 0x2, controller is 0x1, port is 0x3 I googled allot and found the functions pack/unpack, vec and sprintf. But I'm scratching by head how to use the functions to achieve this. Any idea how to achieve this in Perl ?

  • Problem with skipping empty cells while importing data from .xlsx file in asp.net c# application

    - by Eedoh
    Hi to all. I have a problem with reading .xlsx files in asp.net mvc2.0 application, using c#. Problem occurs when reading empty cell from .xlsx file. My code simply skips this cell and reads the next one. For example, if the contents of .xlsx file are: FirstName LastName Age John 36 They will be read as: FirstName LastName Age John 36 Here's the code that does the reading. private string GetValue(Cell cell, SharedStringTablePart stringTablePart) { if (cell.ChildElements.Count == 0) return string.Empty; //get cell value string value = cell.ElementAt(0).InnerText;//CellValue.InnerText; //Look up real value from shared string table if ((cell.DataType != null) && (cell.DataType == CellValues.SharedString)) value = stringTablePart.SharedStringTable.ChildElements[Int32.Parse(value)].InnerText; return value; } private DataTable ExtractExcelSheetValuesToDataTable(string xlsxFilePath, string sheetName) { DataTable dt = new DataTable(); using (SpreadsheetDocument myWorkbook = SpreadsheetDocument.Open(xlsxFilePath, true)) { //Access the main Workbook part, which contains data WorkbookPart workbookPart = myWorkbook.WorkbookPart; WorksheetPart worksheetPart = null; if (!string.IsNullOrEmpty(sheetName)) { Sheet ss = workbookPart.Workbook.Descendants<Sheet>().Where(s => s.Name == sheetName).SingleOrDefault<Sheet>(); worksheetPart = (WorksheetPart)workbookPart.GetPartById(ss.Id); } else { worksheetPart = workbookPart.WorksheetParts.FirstOrDefault(); } SharedStringTablePart stringTablePart = workbookPart.SharedStringTablePart; if (worksheetPart != null) { Row lastRow = worksheetPart.Worksheet.Descendants<Row>().LastOrDefault(); Row firstRow = worksheetPart.Worksheet.Descendants<Row>().FirstOrDefault(); if (firstRow != null) { foreach (Cell c in firstRow.ChildElements) { string value = GetValue(c, stringTablePart); dt.Columns.Add(value); } } if (lastRow != null) { for (int i = 2; i <= lastRow.RowIndex; i++) { DataRow dr = dt.NewRow(); bool empty = true; Row row = worksheetPart.Worksheet.Descendants<Row>().Where(r => i == r.RowIndex).FirstOrDefault(); int j = 0; if (row != null) { foreach (Cell c in row.ChildElements) { //Get cell value string value = GetValue(c, stringTablePart); if (!string.IsNullOrEmpty(value) && value != "") empty = false; dr[j] = value; j++; if (j == dt.Columns.Count) break; } if (empty) break; dt.Rows.Add(dr); } } } } } return dt; }

  • How Does Facebook Know What Image To Parse Out of An Article?

    - by Travis
    First off I want to say that I wasn't really sure where to post this but it is very much programming related. If it is in the wrong spot I apologize and please let me know where I should post it instead. When sharing an article on a friends wall, facebook will grab a thumbnail of the article. How do they always get the right thumbnail from articles? It doesn't grab the logo img element of of http://www.nytimes.com/2010/06/07/world/asia/07convoys.html?hp for example but rather grabs the correct image element that corresponds with the article. I'm looking to do something similar and was wondering of a good way to parse the html to find the image given this example. Thanks.

  • An MP3 parser to extract numbered frames?

    - by Xepoch
    I am writing a streaming application for MP3 (CBR). It is all passthru, meaning I don't have to decode/encode, I just need to pass on the data as I see it come through. I want to be able to count the MP3 frames as they passthru (and some other stuff like throughput calculations). According to the MP3 frame header spec, the sync word appears to be 11 bits of 1s, however I notice (naturally) that the frame payload which I should safely assume to be binary and thus it is not odd at all to see 11 1s in sequence. My questions: Is there a Unix/Linux MP3 parser utility (dd-style) that can pull numbered frames from an MP3 file/pipe? Any perl wisdom here? How does one delineate an MP3 header block from any other binary payload data? and lastly: Is a constant bitrate (CBR) MP3 defined by payload bytes or are the header bytes included in the aggregate # of bytes/bits per any given timeslice? Thanks,

  • PDFParsing & extracting the images only in iPhone application.

    - by sagar
    Hello - Every one. ** : My Query : ** I want to extract only images from entire pdf document. ( Using Objective C - for iPhone Application ) : My Efforts : I have gone through this link which has details regarding different operators of PDF Document. ( http://mail-archives.apache.org/mod_mbox/pdfbox-commits/200912.mbox/%[email protected]%3E ) I also studied this document - ( http://developer.apple.com/mac/library/documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_pdf_scan/dq_pdf_scan.html#//apple_ref/doc/uid/TP30001066-CH220-TPXREF101 ) I also have gone through entire document of PDFReference.pdf ( From original Adobe Site ) PDFReference.pdf (Adobe Document - says that - for image there are following operators ) q Q BI EI I have placed following table get the image myTable = CGPDFOperatorTableCreate(); CGPDFOperatorTableSetCallback(myTable, "q", arrayCallback2); CGPDFOperatorTableSetCallback(myTable, "TJ", arrayCallback); CGPDFOperatorTableSetCallback(myTable, "Tj", stringCallback); I have following arrayCallback2 method for getting image void arrayCallback2(CGPDFScannerRef inScanner, void *userInfo) { // how to extract image from this code // means I have tried too many different ways. following is incorrect way & not giving image // CGPDFStreamRef stream; // represents a sequence of bytes // if (CGPDFDictionaryGetStream (d, "BI", &stream)){ // CGPDFDataFormat t=CGPDFDataFormatJPEG2000; // CFDataRef data = CGPDFStreamCopyData (stream, &t); // } } above arrayCallback2 method is called for operator "q", But I don't know How to extract the image from it. In short. What should be the solution for extracting the images from the pdf documents? Thanks in advance for your kind help. Sagar kothari.

  • Appropriate high level language to deal with binary data

    - by fortran
    Hi, I need to write a small tool that parses a textual input and generates some binary encoded data. I would prefer to stay away from C and the like, in favour of a higher level, (optionally) safer, more expressive and faster to develop language. My language of choice for this kind of tasks usually is Python, but for this case dealing with binary raw data can be problematic if one isn't very careful with the numbers being promoted to bignums, sign extensions and such. Ideally I would like to have records with named bitfields that are portable to be serialised in a consistent manner. (I know that there's a strong point in doing it in a language I already master, although it isn't optimal, but I think this could be a good opportunity to learn something new). Thanks.

  • Little Regular Expression (against HTML) help

    - by Marcos Placona
    Hi, I have the following HTML <p>Some text <a title="link" href="http://link.com/" target="_blank">my link</a> more text <a title="link" href="http://link.com/" target="_blank">more link</a>.</p> <p>Another paragraph.</p> <p>[code:cf]</p> <p>&lt;cfset ArrFruits = ["Orange", "Apple", "Peach", "Blueberry", </p> <p>"Blackberry", "Strawberry", "Grape", "Mango", </p> <p>"Clementine", "Cherry", "Plum", "Guava", </p> <p>"Cranberry"]&gt;</p> <p>[/code]</p> <p>Another line</p> <p><img src="http://image.jpg" alt="Array" /> </p> <p>More text</p> <p>[code:cf]</p> <p>&lt;table border="1"&gt;</p> <p> &lt;cfoutput&gt;</p> <p> &lt;cfloop array="#GroupsOf(ArrFruits, 5)#" index="arrFruitsIX"&gt;</p> <p>  &lt;tr&gt;</p> <p> &lt;cfloop array="#arrFruitsIX#" index="arrFruit"&gt;</p> <p>     &lt;td&gt;#arrFruit#&lt;/td&gt;</p> <p> &lt;/cfloop&gt;</p> <p>  &lt;/tr&gt;</p> <p> &lt;/cfloop&gt;</p> <p> &lt;/cfoutput&gt;</p> <p>&lt;/table&gt;</p> <p>[/code]</p> <p>With an output that looks like:</p> <p><img src="another_image.jpg" alt="" width="342" height="85" /></p> What I'm trying to do, is write a regular expression that will remove all the or , and whenever it finds a , it will replace it with a line-break. So far, my pattern looks like this: /\<p\>(.*?)(<\/p>)/g And I'm replacing the matches with: $1\n It all looks good, but it's also replacing the contents inside the [code][/code] tags, which in this case should not replace the tags at all, so as a result, i would lkike to get rid of the tags, when the content isn't inside the [code] tags. I can't ever get negation right, I know it will be something along the lines of \<p\>^\[code*\](.*?)(<\/p>) But obviously this doesn't work :-) Could anyone please lend me a hand with this regex? BTW, I know I shouldn't be using regular expressions to parse HTML at all. I'm fully aware of that, but still, for this specific case, I'd like to use regex. Thanks in advance

    - by abatishchev
    I'm writing a banking system and my customer wants support both Russian and American numeric standards in decimal digits delimiter. Respectively . and ,. Now only , works properly. Perhaps because of web server's OS format (Russian is set). String like 2000.00 throws a FormatException: Input string was not in a correct format. How to fix that? Are there any other ideas except String.Replace('.', ',') on FormView.ItemInserting event?

  • What sort of object is this and how to use it?

    - by Gary
    What would be the correct name for this type of array? There are 3 main sections and 4 sub-parts consisting of "issuedTime" "text" "url" and "validToTime", how do you start to convert this to an object? If there was only 1 main section, it would be fairly simple to do however with 3 main parts and no identification for each main section has me scratching my head as where to start. Any advise appreciated. [{ "issuedTime":"7:13pm Sunday 13 June 2010", "text":"\nAmended 7:10pm.\n\nText text and more text\n", "url":"\/folder\/fc\/name.png", "validToTime":"12:00am Monday 14 June 2010" },{ "issuedTime":"8:33pm Sunday 13 June 2010", "text":"\nText and more text.\n", "url":"\/folder\/fc\/name.png", "validToTime":"12:00pm Monday 14 June 2010" },{ "issuedTime":"10:40am Sunday 13 June 2010", "text":"\nAnd even more text.", "url":"\/folder\/fc\/name.png", "validToTime":"12:00am Tuesday 15 June 2010" } ]
