Parse XML file on BlackBerry

匆匆过客 提交于 2019-11-27 08:47:01
I want to know how to parse XML data on a BlackBerry. I read somewhere that JSON is good method to parse xml data. Are there any tutorials to parse XML data using JSON, or any other mechanism? Maksym Gontar Parsing XML in Blackberry Simple API for XML (SAX) was developed by the members of a public mailing list (XML-DEV).It gives an event based approach to XML parsing. It means that instead of going from node to node, it goes from event to event. SAX is an event driven interface. Events include XML tag, detecting errors etc, J2ME SAX - see BlackBerry/J2ME - SAX parse collection of objects with

Can anyone tell me how to parse a local XML file stored in the system using SAX, with an example code? Please also tell me where can I find information on that. Steven To read from XML in your app, create a folder in your res folder inside your project called "xml" (lower case). Store your xml in this newly created folder. To load the XML from your resources, XmlResourceParser myxml = mContext.getResources().getXml(R.xml.MyXml);//MyXml.xml is name of our xml in newly created xml folder, mContext is the current context // Alternatively use: XmlResourceParser myxml = getContext().getResources()

Parsing very large XML documents (and a bit more) in java

(All of the following is to be written in Java) I have to build an application that will take as input XML documents that are, potentially, very large. The document is encrypted -- not with XMLsec, but with my client's preexisting encryption algorithm -- will be processed in three phases: First, the stream will be decrypted according to the aforementioned algorithm. Second, an extension class (written by a third party to an API I am providing) will read some portion of the file. The amount that is read is not predictable -- in particular it is not guaranteed to be in the header of the file,

Parsing broken XML with lxml.etree.iterparse

时间秒杀一切 提交于 2019-11-27 07:28:45
I'm trying to parse a huge xml file with lxml in a memory efficient manner (ie streaming lazily from disk instead of loading the whole file in memory). Unfortunately, the file contains some bad ascii characters that break the default parser. The parser works if I set recover=True, but the iterparse method doesn't take the recover parameter or a custom parser object. Does anyone know how to use iterparse to parse broken xml? #this works, but loads the whole file into memory parser = lxml.etree.XMLParser(recover=True) #recovers from bad characters. tree = lxml.etree.parse(filename, parser) #how

Parsing an XML stream with no root element

问题 I need to parse a continuous stream of well-formed XML elements, to which I am only given an already constructed java.io.Reader object. These elements are not enclosed in a root element, nor are they prepended with an XML header like <?xml version="1.0"?>" , but are otherwise valid XML. Using the Java org.xml.sax.XMLReader class does not work, because the XML Reader expects to parse well-formed XML, starting with an enclosing root element. So, it just reads the first element in the stream,

What are the differences between DOM, SAX and StAX XML parsers? [closed]

I'm developing a RSS feed aggregator with Apache Tomcat. I was wondering which parser to use in order to read RSS feeds. Should I use DOM, SAX or StAX? I know that there are libraries specific to read RSS feeds with java but since this is a university project I am not supposed to use those. Thank you. OldCurmudgeon It mostly depends on your needs. Each has it's own features. DOM - pull the whole thing into memory and walk around inside it. Good for comparatively small chunks of XML that you want to do complex stuff with. XSLT uses DOM. SAX - Walk the XML as it arrives watching for things as

Howto let the SAX parser determine the encoding from the xml declaration?

问题 I'm trying to parse xml files from different sources (over which I have little control). Most of the them are encoded in UTF-8 and don't cause any problems using the following snippet: SAXParserFactory factory = SAXParserFactory.newInstance(); SAXParser parser = factory.newSAXParser(); FeedHandler handler = new FeedHandler(); InputSource is = new InputSource(getInputStream()); parser.parse(is, handler); Since SAX defaults to UTF-8 this is fine. However some of the documents declare: <?xml

Android SAX parser not getting full text from between tags

I've created my own DefaultHandler to parse rss feeds and for most feeds it's working fine, however, for ESPN, it is cutting off part of the article url due to the way ESPN formats it's urls. An example of a full article url from ESPN.. http://sports.espn.go.com/nba/news/story?id=5189101&campaign=rss&source=ESPNHeadlines The problem is for some reason the DefaultHandler characters method is only getting this from the tag that contains the above url. http://sports.espn.go.com/nba/news/story?id=5189101 As you can see, it's cutting everything off the url from the ampersand escape code and after.
