stax

问题 My goal is to read objects (featureMember) into DOM, change them and write back into new XML. XML is too big to use DOM itself. I figured what I need is StAX and TransformerFactory, but I can't make it work. This is what I've done till now: private void change(File pathIn, File pathOut) { try { XMLInputFactory factory = XMLInputFactory.newInstance(); XMLOutputFactory factoryOut = XMLOutputFactory.newInstance(); TransformerFactory tf = TransformerFactory.newInstance(); Transformer t = tf

问题 I would like to copy multiple XML nodes from a source XML file to a target file. Both source and target files are very large, so I will use StAX. Typically the file I'm trying to process looks as follows: <root> <header> <title>A List of persons</title> </header> <person> <name>Joe</name> <surname>Bloggs</surname> </person> <person> <name>John</name> <surname>Doe</surname> </person> . . etc... </root> The target files should be in the following format: <root> <header> <title>A List of persons

问题 Is there a way to accurately gather the byte offsets of xml tags using the XMLStreamReader? I have a large xml file that I require random access to. Rather than writing the whole thing to a database, I would like to run through it once with an XMLStreamReader to gather the byte offsets of significant tags, and then be able to use a RandomAccessFile to retrieve the tag content later. XMLStreamReader doesn't seem to have a way to track character offsets. Instead people recommend attaching the

问题 this is my first time using StAX for parsing XML documents (still in the learning stage). During the process to parse an XML document using XMLStreamReader and generate a copy of the document using XMLStreamWriter, I encountered the following warning represented as a comment in the output of the writer: <!-- Exception scanning External DTD Subset. True contents of DTD cannot be determined. Processing will continue as XMLInputFactory.IS_VALIDATING == false. --> I understood the cause of the

问题 i was trying to measure time needed for StAX and DOM to create two same documents. I dont know why DOM is faster in creating XML. Maybe my code for StAX writer is not very good. so here it is StAX(longer code) public static final int pocet =100000; try { String encoding = "UTF-8"; XMLOutputFactory f = XMLOutputFactory.newInstance(); XMLStreamWriter w = f.createXMLStreamWriter( new FileOutputStream(subor), encoding); w.writeStartDocument(encoding, "1.0"); w.writeCharacters("\r\n"); w

问题 I'm using AsyncTask to download and parse XML content from i-net. Downloading and parsing of the xml happens in doInBackground() method. The "dalvikvm" encounters a problem - it could not find a method. Here is the log of LogCat: 06-30 13:26:41.148: DEBUG/dalvikvm(507): GC freed 796 objects / 68088 bytes in 112ms 06-30 13:26:41.667: INFO/ActivityManager(52): Displayed activity com.news.reader/.SplashScreen: 5305 ms (total 63417 ms) 06-30 13:26:45.097: INFO/ActivityManager(52): Starting

问题 I'm using StAX to read my file, which has some Base64 data in it, and saving it into the db using Hibernate. XML: <root> <base64>lololencoded12</base64> <base64>encodedlolos32</base64> ............................... </root> Code to read and save: xmlif = (XMLInputFactory2) XMLInputFactory2.newInstance(); xmlif.setProperty(XMLInputFactory.IS_REPLACING_ENTITY_REFERENCES, Boolean.FALSE); xmlif.setProperty(XMLInputFactory.IS_SUPPORTING_EXTERNAL_ENTITIES, Boolean.FALSE); xmlif.setProperty

问题 I was hoping the following would be parseable in StAX, <something a="b"/> <something a="b"/> But it chokes when you reach the second element. As there is no common root element. (I'm not too sure why a pull parser cares about this particular issue... anyway...) I can fake a root element, e.g. Guava: InputSupplier<Reader> join = CharStreams.join( newReaderSupplier("<root>"), newReaderSupplier(new File("...")), newReaderSupplier("</root>")); XMLInputFactory xif = XMLInputFactory.newInstance();

问题 Starting learning the StAX, using XMLStreamReader, I faced with some problem. How can I get ALL content between tags as Text? I mean, I know name of needed tag, and when I find it, I must go to the close tag, and everything I found between them I must append at some string. For example, we have something like <rootTag> ... <someTag> Some text content and other tags here… </someTag > <tagINeed> <someinternalTag1> <someinternalTag11> Some text content.. </someinternalTag11> ... <
