Reading big chunk of xml data from socket and parse on the fly

瘦欲@ 提交于 2019-11-29 12:03:31
I am working on an android client which reads continues stream of xml data from my java server via a TCP socket. The server sends a '\n' character as delimiter between consecutive responses. Below given is a model implementation.. <response1> <datas> <data> ..... ..... </data> <data> ..... ..... </data> ........ ........ </datas> </response1>\n <--- \n acts as delimiter ---/> <response2> <datas> <data> ..... ..... </data> <data> ..... ..... </data> ........ ........ </datas> </response2>\n Well I hope the structure is clear now. This response is transmitted from server zlib compressed. So I

I'm trying to remove all the project1 nodes (along with their child elements) from the below sample xml document ( original document is about 30 GB ) using SAX parser.It would be fine to have a separate modified file or ok with the in-line edit. sample.xml <ROOT> <test src="http://dfs.com">Hi</test> <project1>This is old data<foo></foo></project1> <bar> <project1>ty</project1> <foo></foo> </bar> </ROOT> Here is my attempt.. parser.py from xml.sax.handler import ContentHandler import xml.sax class MyHandler(xml.sax.handler.ContentHandler): def __init__(self, out_file): self._charBuffer = []

How to solve the XML parsing performance issue on Android

我只是一个虾纸丫 提交于 2019-11-28 22:11:14
问题 I have to read a XML file with about ~4000 lines on Android. First I tried the SimpleXML library because it's the easiest and it took about 2 minutes on my HTC Desire. So I thought maybe SimpleXML is so slow because of reflection and all the other magic that this library uses. I rewrote my parser and used the built-in DOM parsing method with some special attention for performance. That helped a bit but it still took about 60 seconds which is still totally unacceptable. After a bit of research

What is 'Push Approach' and 'Pull Approach' to parsing?

允我心安 提交于 2019-11-28 19:15:05
Under the push parsing approach, a push parser generates synchronous events as a document is parsed, and these events can be processed by an application using a callback handler model This is the text given in the book Pro XML Development with Java about SAX 2.0. As for StAX, the book says: Under the pull approach, events are pulled from an XML document under the control of the application using the parser. I want to ask, what is the meaning of the highlighted text ? An answer befitting a beginner is appreciated :) Basically, a push is when the parser says to some handler, "I have a foo, do

SAX parser vs XMLPull parser

空扰寡人 提交于 2019-11-28 16:01:20
I understand the difference between how the SAX parser works vs the XMLPull parser. In fact there's a pretty good explanation here: http://www.firstobject.com/xml-reader-sax-vs-xml-pull-parser.htm The article is a bit .NET centric but the concepts apply. While I agree with the author's opinion that the Pull parser is easier to work with, I'm pretty confused as to which type of parser would be better in which situations. If anyone could shed any light and point me to some more reading I would appreciate it. Thank you. I find that they both suck. (And I have a better solution to suggest) You

With SAX Parser, get an attribute's value

二次信任 提交于 2019-11-28 13:18:18
I am parsing XML from the web using Android. The code below shows a sample of the XML. The problem I'm having is I can't get the string value of the item tag. When I use name = attributes.getQName(i); it outputs the name, not the value of the attribute. <weatherdata> <timetags> <item name="date"> <value>20/04/2012</value> <unit/> <image/> <class>dynamic</class> <description>The current date</description> </item> use attributes.getValue(i); instead of attributes.getQName(i); because as doc says : getQName : Return an attribute's qualified (prefixed) name. getValue : Look up an attribute's value

Open XML file from res/xml in Android

I created a Java application which opens an xml file that looks something like this: <AnimalTree> <animal> <mammal>canine</mammal> <color>blue</color> </animal> <!-- ... --> </AnimalTree> And I can open it using: File fXmlFile = getResources.getXml("res/xml/data.xml"); DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); Document doc = dBuilder.parse(fXmlFile); doc.getDocumentElement().normalize(); NodeList animalNodes = doc.getElementsByTagName("animal"); Then I can simply create a node, push the object into a
