  • Use regular expressions to match an ? but not a \?

    - by J.Milly
    I have a PHP regular expression that has been functioning fairly well to parse some odd legacy client templates until recently when we found an escaped question mark (\?) included in a template expression. I'm not strong enough with my regular expression-fu to wrap my feeble noodle around a negative look ahead or some techno-mumbo-jumbo so, tips or points in the right direction would be greatly appreciated. My PHP: preg_match_all("/\{\{IF (.*)\?(.*):(.*)\}\}/U", $template, $m, PREG_SET_ORDER);

  • Regular expression works normally, but fails when placed in an XML schema

    - by Eli Courtwright
    I have a simple doc.xml file which contains a single root element with a Timestamp attribute: <?xml version="1.0" encoding="utf-8"?> <root Timestamp="04-21-2010 16:00:19.000" /> I'd like to validate this document against a my simple schema.xsd to make sure that the Timestamp is in the correct format: <?xml version="1.0" encoding="utf-8"?> <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="root"> <xs:complexType> <xs:attribute name="Timestamp" use="required" type="timeStampType"/> </xs:complexType> </xs:element> <xs:simpleType name="timeStampType"> <xs:restriction base="xs:string"> <xs:pattern value="(0[0-9]{1})|(1[0-2]{1})-(3[0-1]{1}|[0-2]{1}[0-9]{1})-[2-9]{1}[0-9]{3} ([0-1]{1}[0-9]{1}|2[0-3]{1}):[0-5]{1}[0-9]{1}:[0-5]{1}[0-9]{1}.[0-9]{3}" /> </xs:restriction> </xs:simpleType> </xs:schema> So I use the lxml Python module and try to perform a simple schema validation and report any errors: from lxml import etree schema = etree.XMLSchema( etree.parse("schema.xsd") ) doc = etree.parse("doc.xml") if not schema.validate(doc): for e in schema.error_log: print e.message My XML document fails validation with the following error messages: Element 'root', attribute 'Timestamp': [facet 'pattern'] The value '04-21-2010 16:00:19.000' is not accepted by the pattern '(0[0-9]{1})|(1[0-2]{1})-(3[0-1]{1}|[0-2]{1}[0-9]{1})-[2-9]{1}[0-9]{3} ([0-1]{1}[0-9]{1}|2[0-3]{1}):[0-5]{1}[0-9]{1}:[0-5]{1}[0-9]{1}.[0-9]{3}'. Element 'root', attribute 'Timestamp': '04-21-2010 16:00:19.000' is not a valid value of the atomic type 'timeStampType'. So it looks like my regular expression must be faulty. But when I try to validate the regular expression at the command line, it passes: >>> import re >>> pat = '(0[0-9]{1})|(1[0-2]{1})-(3[0-1]{1}|[0-2]{1}[0-9]{1})-[2-9]{1}[0-9]{3} ([0-1]{1}[0-9]{1}|2[0-3]{1}):[0-5]{1}[0-9]{1}:[0-5]{1}[0-9]{1}.[0-9]{3}' >>> assert re.match(pat, '04-21-2010 16:00:19.000') >>> I'm aware that XSD regular expressions don't have every feature, but the documentation I've found indicates that every feature that I'm using should work. So what am I mis-understanding, and why does my document fail?

  • reverse this function

    - by ooo
    i have code that takes a csharp datetime and converts it into a long to plot in the "flot" graph. here is the code public static long GetJavascriptTimestamp(DateTime input) { TimeSpan span = new TimeSpan(DateTime.Parse("1/1/1970").Ticks); DateTime time = input.Subtract(span); return (long)(time.Ticks / 10000); } I now need an opposite function where i take this long value and get the csharp datetime object back. any idea if the above method can be reversed ?

  • Apostrophe turning to question mark when using php handler in .htaccess

    - by Tony Deefer
    I have a .htm page on a site, that for reasons I won't go into cannot be renamed .php I have added some php code to the top of the page, (sets a cookie and redirects to another page) and added the following to .htaccess to parse the .htm file as php AddHandler application/x-httpd-php5 .html .htm As soon as this is added to .htaccess all apostrophe's change into questions marks. Using charset UTF-8 Can anyone offer a solution that does not involve renaming the file .php? Many thanks

  • Looking for a good text parsing library for C#

    - by Chris Stewart
    Has anyone run across a quality library that will parse, line by line, CSV, tab-delimited, and Excel files? I've started to do it manually but have noticed some of the intricacies in parsing a comma-delimited file. Such as situations where a cell has a comma in it as part of the data (blah,\"LastName, Jr.\",blah,blah).

  • Equivalent of libwww-perl in .NET or Java

    - by voidvector
    I have written a crawler in Perl awhile back and it was super simple giving the high-level capability of libwww-perl. It is so straight forward in fact, it can take the raw HTML response of one request, and create the next HTTP request for you from the FORMs on that page (as in it will parse the HTML for you). Does anyone know any library like this on .NET or Java? Selenium is out of question because it requires the browser to be open, which we cannot accommodate in our implementation)

  • Is there a jQuery webscrapper out there?

    - by victor hugo
    I'm trying to pullout some info from an external site using jQuery and Adobe AIR. Right now I'm using a hidden div and jQuery's load function to load fragments of the external site, once the info is loaded I parse some info with selectors. This is fine but it's kinda dirty and I need to perform this several times (don't want to need many hidden divs). Just wondering if anybody knows a good webscrapper written in jQuery or maybe another method I'm missing

  • Parsing a .NET DataSet returned from a .NET Web Service in Java

    - by Chris Dail
    I have to consume a .NET hosted web service from a Java application. Interoperability between the two is usually very good. The problem I'm running into is that the .NET application developer chose to expose data using the .NET DataSet object. There are lots of articles written as to why you should not do this and how it makes interoperability difficult: http://www.hanselman.com/blog/ReturningDataSetsFromWebServicesIsTheSpawnOfSatanAndRepresentsAllThatIsTrulyEvilInTheWorld.aspx http://www.lhotka.net/weblog/ThoughtsOnPassingDataSetObjectsViaWebServices.aspx http://aspnet.4guysfromrolla.com/articles/051805-1.aspx http://www.theserverside.net/tt/articles/showarticle.tss?id=Top5WSMistakes My problem is that despite this not being recommended practice, I am stuck with having to consume a web service returning a DataSet with Java. When you generate a proxy for something like this with anything other than .NET you basically end up with an object that looks like this: @XmlElement(namespace = "http://www.w3.org/2001/XMLSchema", required = true) protected Schema schema; @XmlAnyElement(lax = true) protected Object any; This first field is the actual schema that should describe the DataSet. When I process this using JAX-WS and JAXB in Java, it bring all of XS-Schema in as Java objects to be represented here. Walking the object tree of JAXB is possible but not pretty. The any field represents the raw XML for the DataSet that is in the schema specified by the schema. The structure of the dataset is pretty consistent but the data types do change. I need access to the type information and the schema does vary from call to call. I've though of a few options but none seem like 'good' options. Trying to generate Java objects from the schema using JAXB at runtime seems to be a bad idea. This would be way too slow since it would need to happen everytime. Brute force walk the schema tree using the JAXB objects that JAX-WS brought in. Maybe instead of using JAXB to parse the schema it would be easier to deal with it as XML and use XPath to try and find the type information I need. Are there other options I have not considered? Is there a Java library to parse DataSet objects easily? What have other people done who may have similar situations?

  • Django - markup parser in template or view?

    - by Amit Ron
    I am building a website where my pages are written in MediaWiki Markup, for which I have a working parser function in Python. Where exactly do I parse my markup: in the view's code, or in the template? My first guess would be something like: return render_to_response( 'blog/post.html', {'post': post, 'content': parseMyMarkup(post.content) }) Is this the usual convention, or should I do something different?

  • Insertions into Zipper trees on XML files in Clojure

    - by ivar
    I'm confused as how to idiomatically change a xml tree accessed through clojure.contrib's zip-filter.xml. Should be trying to do this at all, or is there a better way? Say that I have some dummy xml file "itemdb.xml" like this: <itemlist> <item id="1"> <name>John</name> <desc>Works near here.</desc> </item> <item id="2"> <name>Sally</name> <desc>Owner of pet store.</desc> </item> </itemlist> And I have some code: (require '[clojure.zip :as zip] '[clojure.contrib.duck-streams :as ds] '[clojure.contrib.lazy-xml :as lxml] '[clojure.contrib.zip-filter.xml :as zf]) (def db (ref (zip/xml-zip (lxml/parse-trim (java.io.File. "itemdb.xml"))))) ;; Test that we can traverse and parse. (doall (map #(print (format "%10s: %s\n" (apply str (zf/xml-> % :name zf/text)) (apply str (zf/xml-> % :desc zf/text)))) (zf/xml-> @db :item))) ;; I assume something like this is needed to make the xml tags (defn create-item [name desc] {:tag :item :attrs {:id "3"} :contents (list {:tag :name :attrs {} :contents (list name)} {:tag :desc :attrs {} :contents (list desc)})}) (def fred-item (create-item "Fred" "Green-haired astrophysicist.")) ;; This disturbs the structure somehow (defn append-item [xmldb item] (zip/insert-right (-> xmldb zip/down zip/rightmost) item)) ;; I want to do something more like this (defn append-item2 [xmldb item] (zip/insert-right (zip/rightmost (zf/xml-> xmldb :item)) item)) (dosync (alter db append-item2 fred-item)) ;; Save this simple xml file with some added stuff. (ds/spit "appended-itemdb.xml" (with-out-str (lxml/emit (zip/root @db) :pad true))) I am unclear about how to use the clojure.zip functions appropriately in this case, and how that interacts with zip-filter. If you spot anything particularly weird in this small example, please point it out.

  • base 64 URL decode with Ruby/Rails?

    - by seth.vargo
    I am working with the Facebook API and Ruby on Rails and I'm trying to parse the JSON that comes back. The problem I'm running into is that Facebook base64URL encodes their data. There is no built-in base64URL decode for Ruby. For the difference between a base64 encoded and base64URL encoded, see wikipedia. How do I decode this using Ruby/Rails? Edit: Because some people have difficulty reading - base64 URL is DIFFERENT than base64
