  • python regex for repeating string

    - by Lars Nordin
    I am wanting to verify and then parse this string (in quotes): string = "start: c12354, c3456, 34526;" //Note that some codes begin with 'c' I would like to verify that the string starts with 'start:' and ends with ';' Afterward, I would like to have a regex parse out the strings. I tried the following python re code: regx = r"V1 OIDs: (c?[0-9]+,?)+;" reg = re.compile(regx) matched = reg.search(string) print ' matched.groups()', matched.groups() I have tried different variations but I can either get the first or the last code but not a list of all three. Or should I abandon using a regex?

  • 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" } ]

  • jQuery display text nested in paragraphs inside a div

    - by user961627
    I have HTML that looks something like this: <div class='textbox' data-title='Sometitle'> <div class='textareaedit'> <p><strong>Test sample text</strong></p> </div> </div> I'm sometimes going to have a few different <p> tags inside the textareaedit divs, and sometimes strong tags around the text inside the <p> (as in this example), and sometimes a span tag, and sometimes it's going to be without further tags inside the <p>. I want to iterate through each textbox on my page, grab its title and also the text nested inside <p> tags in textareaedit. I'm giving the output via console for testing. This is my jQuery code, but I get no output for the second console.log() line: $('.textbox').each(function() { $this = $(this); console.log($this.attr('data-title')+ ":\n"); $this.children('textareadit').children('p').each(function(){ console.log($(this).html()); // not giving any output, it's blank }); }); I tried $(this).text() as well, but no difference. You may think this example has the sample text inside <strong> tags within the <p>, but I've also tried the same example without the strong, where the text was the direct child of <p>, but it didn't make a difference. How can I capture the text?

  • Python/YACC Lexer: Token priority?

    - by Rosarch
    I'm trying to use reserved words in my grammar: reserved = { 'if' : 'IF', 'then' : 'THEN', 'else' : 'ELSE', 'while' : 'WHILE', } tokens = [ 'DEPT_CODE', 'COURSE_NUMBER', 'OR_CONJ', 'ID', ] + list(reserved.values()) t_DEPT_CODE = r'[A-Z]{2,}' t_COURSE_NUMBER = r'[0-9]{4}' t_OR_CONJ = r'or' t_ignore = ' \t' def t_ID(t): r'[a-zA-Z_][a-zA-Z_0-9]*' if t.value in reserved.values(): t.type = reserved[t.value] return t return None However, the t_ID rule somehow swallows up DEPT_CODE and OR_CONJ. How can I get around this? I'd like those two to take higher precedence than the reserved words.

    Given a string named line whose raw version has this value: \rRAWSTRING how can I detect if it has the escape character \r?

    - by Michael Altman
    I have the following HTML that is within a larger document <br /> Important Text 1 <br /> <br /> Not Important Text <br /> Important Text 2 <br /> Important Text 3 <br /> <br /> Non Important Text <br /> Important Text 4 <br /> I'm currently using BeautifulSoup to obtain other elements within the HTML, but I have not been able to find a way to get the important lines of text between <br /> tags.

  • 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?

  • removing phone number from a document.

    - by Grant Collins
    Hi, I've got a challenge that I am hoping that the SO community is able to help me with. I trying to parse a lot of html documents in my PHP application to remove personal details, such as names, addresses and phone numbers. I can remove most of these details without too much trouble, however the phone number is a real problem for me. My idea is to take the text from these documents and the use a regex to identify the phone numbers and replace them with another value such as 'xxxx'. I've got 2 regex that I am using one for UK landline numbers and one for UK cell/mobile numbers. However when I try and run them against the text it just returns an empty string. I am using the following preg_replace code: $pattens = array( '/^(((\+44\s?\d{4}|\(?0\d{4}\)?)\s?\d{3}\s?\d{3})|((\+44\s?\d{3}|\(?0\d{3}\)?)\s?\d{3}\s?\d{4})|((\+44\s?\d{2}|\(?0\d{2}\)?)\s?\d{4}\s?\d{4}))(\s?\#(\d{4}|\d{3}))?$/', '/^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/' ); $replace = array('xxxxx', 'xxxxx'); //do the search for the numbers. $updatedContents = preg_replace($pattens, $replace, $htmlContents); At the moment this is causing me a lot of head scratching as I thought that I had this nailed, but at the moment I can't see what's wrong?? I am sure that it is something really simple. Thanks, Grant

  • 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.

  • Relative Dates with Datejs

    - by Prasanna
    I have a requirement where in, I have to parse the dates relative to a date object returned from the server side. But the datejs library always considers only the browsers date object. The situation is something like this: The server gives back the date in PST and the browser is in IST. And all the inputs are getting parsed with respect to the current date in IST instead of current date in PST. Is there any way I could resolve this. Or could you suggest any workarounds. Thanks in advance.

  • 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?

  • BigInteger.Parse() on hexadecimal number gives negative numbers.

    - by brickner
    I've started using .NET 4 System.Numerics.BigInteger Structure and I've encountered a problem. I'm trying to parse a string that contains a hexadecimal number with no sign (positive). I'm getting a negative number. For example, I do the following two asserts: Assert.IsTrue(System.Int64.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "Int64"); Assert.IsTrue(System.Numerics.BigInteger.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "BigInteger"); The first assert succeeds, the second assert fails. I actually get -8 instead of 8 in the BigInteger. The problem seems to be when I'm the hexadecimal starts with 1 bit and not 0 bit (a digit between 8 and F inclusive). If I add a leading 0, everything works perfectly. Is that a bad usage on my part? Is it a bug in BigInteger?

  • JSON parse data in javascript from php

    - by Stefania
    I'm trying to retrieve data in a javascript file from a php file using json. $items = array(); while($r = mysql_fetch_array($result)) { $rows = array( "id_locale" => $r['id_locale'], "latitudine" => $r['lat'], "longitudine" => $r['lng'] ); array_push($items, array("item" => $rows)); } ECHO json_encode($items); and in the javascript file I try to recover the data using an ajax call: $.ajax({ type:"POST", url:"Locali.php", success:function(data){ alert("1"); //var obj = jQuery.parseJSON(idata); var json = JSON.parse(data); alert("2"); for (var i=0; i<json.length; i++) { point = new google.maps.LatLng(json[i].item.latitudine,json[i].item.longitudine); alert(point); } } }) The first alert is printed, the latter does not, it gives me error: Unexpected token <.... but I do not understand what it is. Anyone have any idea where am I wrong? I also tried to recover the data with jquery but with no positive results.

  • building objects from xml file at runtime and intializing, in one pass?

    - by KaluSingh Gabbar
    I have to parse the XML file and build objects representation based on that, now once I get all these data I create entries in various database for these data objects. I have to do second pass over that for value as in the first pass all I could do is build the assets in various databases. and in second pass I get the values for all the data and put it in the database. I have a feeling that this can be done in a single pass but I just want to see what are your opinions. As I am just a student who started with professional work, experienced ppl please help. Can someone who have ideas or done similar work, please provide some light on the topic so that I can think over the possibility of the work and get the prototype going based on your suggestion. Thanks a lot for your precious time, I honestly appreciate it.

  • Convert an XML object back into a string in ColdFusion

    - by jpmyob
    In ColdFusion, I can parse a string of XML formatted data into an XML Object using xmlParse(). How can I convert it back into a string? When I tried using toString() it throws an error that "it can't convert complex object to simple objects....", which is ironic because that's what it's supposed to do. I need to use XMLTransform() which requires the first argument to be an xml string. But I also need to use xmlSearch() to get a node to pass into my transform, and xmlSearch returns an xmlObject. So now I need to put that object back into xml string format to pass into xmlTransform.

  • 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.
