I am using SAXParser to parse an XML document having three different tags. But in the result I get the value of only "one tag and not Other two tags. Can someone explain?
My XML is :
<outertag>
<innertag>hello</innertag>
<othertag>good morning</othertag>
<thirdtag Attribute="its a pleasant day"/>
</outertag>

My Android phone wont read the tags of my .MP4-music files. I have tried editing the tags with MP2tag, but it didn't help.
View 2 Replies View RelatedI have had a problem with no matter what android phone I have. This has been doing it for quite some time but I dealt with it but last night I lost 12 GB of music so here it is:
Whenever I move music in these situations, it will erase all ID3 Tag information (Artist, Album, etc) and all it has is the file name. I had 2000 songs with artist names and all, but when moved it all became unknown artist. Here are the situations:
Galaxy S3: Moving Music from one folder to another (Like from a Download folder to my music folder on external SD). Or from moving music from internal to external or vice versa.
Optimus G: Moving music from one folder to another on the internal storage (Again, like from a download to music folder).
Evo 4G: Just moving from folder to folder.
All this is done with ES. File explorer. I tried other but they do it too. It can not be device specific because it happens on almost any android. All songs are in MP4/MP3 format and maybe some .wma.
I have an API. I'm using that requires me to POST instead of use GET to submit my credentials before receiving back my XML response. I've parsed a bunch of various XML services like this, but this is the first time I've run across having to post to the URL. Basically they want a username and password parameter submitted as a post to the URL before the XML is fed back. Does anyone have a working example, or maybe able to point me in the right direction?

View 2 Replies View RelatedI am using a saxparser to read RSS XML from the web and populate listviews. Everything works fine until I come across malformed XML, usually encoding related, and my reader falls over. I have changed it so that it gets as many items parsed and populated before falling over (by default if it finds a malformed XML, then it will give up and return an empty collection). The problem is, the next time I try and view that feed (or any other feed), it still has the contents after the malformed bit hanging around.
For example, the first time it now shows all the items upto the malformed item, if I refresh, it will only show items after, refresh again, it will show items upto and so forth. The weird thing is, I create a new instances of everything every time. So I don't understand why stuff is handing around. It's like there is some read pointer, or connection that needs to be closed and reset, but I can't for the life of me work out what or where!
My GetFeed method:
private RSSFeed getFeed(String urlToRssFeed) {
SAXParserFactory factory;
SAXParser parser; XMLReader xmlreader;
URL url; InputSource is;
try { url = new URL(urlToRssFeed);
factory = SAXParserFactory.newInstance();
factory.setValidating(false);
parser = factory.newSAXParser();
xmlreader = parser.getXMLReader();
xmlreader.setContentHandler(m_FeedHandler);
is = new InputSource(url.openStream());
xmlreader.parse(is); m_ErrorCode = NOERROR;
} catch (SAXParseException e) { e.printStackTrace();
m_ErrorCode = XMLFORMAT;
} catch (Exception e) { e.printStackTrace();
m_ErrorCode = CONNECTION;
} finally { is = null;
url = null; parser = null; factory = null;
return m_FeedHandler.getFeed();
//May be complete, partial or empty.
} }
I'm using the SAX parser to read some RSS feeds and have found a problem. Some feeds, for example CNN Money Top Stories, have embedded some characters in their content, i.e. the copyright symbol. Well, that's not valid XML and the SAX Parser fails with an exception "invalid token". The only help I have seen given is to fix the XML at the source and that's not an option obviously. So, I can think of 2 options and they both stink:
(a) read the content first, scrub it, and then pass it to the parser.
(b) Use DOM instead of SAX.
What I *want* to do is make the parser a little more forgiving and just accept or discard/ignore the bad text. I'm not have any luck with setErrorHandler. My error handler does not get called.
I have been trying to use the youtube APIs on the Android Platform (version 1.6) and have been stuck with the SAXParser whenever I send out a query from the following line of code:
VideoFeed videoFeed = service.query(query, VideoFeed.class);
I initially had errors with the SAXParser for which I applied the patch suggested here:
https://code.google.com/p/android/issues/detail?id=9493
After this, the previous error that I had which called an ExternalParametersEntities exception was resolved but I now get a Verify Error:
com.google.gdata.util.common.xml.parsing.SecureGenericXMLFactory $SecureSAXParserFactory
Would anyone know how to get around this error? Is there any other way to use the youtube API query on an Android platform?
I'm using a SAXParser to parse an XML document and its getting stuck on certain symbols like the 'trademark' symbol and I think even double- quotes". I really don't need these characters so it would be fine if the parser just skips over these. Instead it throws an exception and quits parsing the document. What can I do?

Here is my SAXHandler class:

I am using SAXParser to parse an html page (any better solution?) and have this exception:
W/System.err( 1358): org.apache.harmony.xml.ExpatParser $ParseException: At line 1, column 59: not well-formed (invalid token)
I have reduced the page to this:
<div id="submenu"><a href="/compte/console.pl? id=382730&idt=1cf6b94aa1a4cf84"></a></div>
And what causes the exception is the '&' inside the href attribute value.
Here is a minimalist test code:
DefaultHandler emptySaxHandler = new DefaultHandler() {};
String xmlstr = "<div id="submenu"><a href="/compte/console.pl?id=382730&idt=1cf6b94aa1a4cf84"></a></div>";
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser saxParser = factory.newSAXParser();
saxParser.parse(new ByteArrayInputStream(xmlstr.getBytes ()),emptySaxHandler);
Is this a normal behaviour or kind of bug? If normal, what should do to preprocess the string before parsing?
Im using the SAXParser object do parse the actual XML.
This is normally done by passing a URL to the XMLReader.Parse method. Because my XML is coming from a POST request to a webservice, I am saving that result as a String and then employing StringReader / InputSource to feed this string back to the XMLReader.Parse method.
However, something strange is happening at the 2001st character of the XMLstring. The 'characters' method of the document handler is being called TWICE in between the startElement and endElement methods, effectively breaking my string (in this case a project title) into two pieces. Because I am instantiating objects in my characters method, I am getting two objects instead of one.
This line, about 2000 chars into the string fires 'characters' two times, breaking between "Lower" and "Level"
<title>SUMC-BOOKSTORE, LOWER LEVEL RENOVATIONS</title>
When I bypass the StringReader / InputSource workaround and feed a flat XML file to XMLReader.Parse, it works absolutely fine.
Something about StringReader and or InputSource is somehow screwing this up.
Here is my method that takes and XML string and parses is through the SAXParser.
CODE:.............
How to not have 'characters' firing off twice when I get to this point in the XML String.
Or, show me how to use a POST request and still pass off the URL to the Parse function.
I am parsing xml using the SAXParser and want to know if this is the right way to implement the characters method. Assume there's a class-level String variable named elementValue and it is initialized to "" in the startElement method.
Here is the characters method:
@Override
public void characters(char[] ch, int start, int length) {
String charsToAppend = new String(ch, start, length);
elementValue = elementValue + charsToAppend;
}
Is it correct that we need to append to the value we have so far and is the append being done correctly? Also, why does the characters method give the start index? Won't it be zero every time?
I'm having a XML file like:
CODE:....................

How to get only that 2 tags?...
I'm parsing an xml file from web service,it contains html tags,when i use the particular node like description ,the parser simply escapes to parse.for example below content i use to parse it simply skipped from parsing.
CODE:.........
How can i resolve this issue.please help me.
I wonder if anyone knows whether the built in media player uses some kind of caching of mp3 files ID3 tag information, because after I change the tag of a file it doesn't show the updated data. Only after the phone restart, I guess after /sdcard remount, does it show correct tag info.
