string which contains an ampersand is not shown correctly

[GoogleCodeExporter]

It would help if you could attach a full plist file that is parsing incorrectly.

Perhaps your problem has to do with the fact that ampersands must be escaped in 
xml.  For example, you can't do this:

<string>http://www.example.com?param1=1234¶m2=abcd</string>

you must instead do this:

<string>http://www.example.com?param1=1234&param2=abcd</string>

I'm not sure if that is your problem, though.  I get an exception if I don't 
escape the ampersand, not a string truncation.

Also if  a string�object contains ' the text from the '&' is missing 

Is this same issue?

@durkjae: Probably - a string with "'" in it should be written as "'" in 
the xml.  In any case, I don't get an error when I do that, "'" gets translated 
back into a single quote just fine when I try it.

Please, please, please!  Attach the plist file you're having trouble with.  
Makes debugging so much easier.

p.s. you probably shouldn't be typing xml - use an xml writer app (or this 
library) which will do the escaping for you.

@keith: 

the ampersand is correctly escaped (&)

every text that contains an ampersand will be cropped (you can try it for 
yourself)

i think the issue has something to do with the dom parser

I had use this library(r45, r46) on Android 2.2 (API 8)

following data (refer attacted file) for parsing

...
 <key>filepath</>
<string>Girl's Generation</string>
...

String filepath = rootDict.objectForKey("filepath").toString();

result from above code

The filepath has "Girl".  Not "Girl's Generation"

Hmm, works fine for me on both OS X and Windows.  Must be something up with the 
Android XML parser.

This thread may have something to do with it: 
http://stackoverflow.com/questions/1973483/android-xml-parsing-omitting-amp

We are just grabbing the first child of <string> from the parser (see 
XMLPropertyListParser.java:169).  If the Android XML parser is returning three 
chunks of text, we'd miss the last two.

I'll have to think about the right way to fix this.  This "feature" might 
affect more than just <string>.

Here's a bug filed against Android about this: 
http://code.google.com/p/android/issues/detail?id=2607

Upshot: try adding "docBuilderFactory.setCoalescing(true);" right after 
"docBuilderFactory.setIgnoringComments(true);" in XMLPropertyListParser.java:54

Let me know if that works.  Sorry I can't try it myself, I don't have an 
Android environment to test on.

Oh! works fine on Android.

Thanks for your advice.

...
private static synchronized void initDocBuilderFactory() throws 
ParserConfigurationException {
        docBuilderFactory = DocumentBuilderFactory.newInstance();
        docBuilderFactory.setIgnoringComments(true);
        docBuilderFactory.setCoalescing(true); 
    }
...

I am using rev52 and I am still seeing this problem. 

In the attached plist if you go to
AllSports > Item 0 > AllFeeds > Item 0 > FeedUrl you will see 
http://www.meangreensports.com/rss.dbml?db_oem_id=1800&media=results

but when ever I do an objectForKey on "FeedUrl" I get

http://www.meangreensports.com/rss.dbml?db_oem_id=1800

everything after the & is cut off. Any suggestions?

Please check whether you are actually using r52.

If you really are, please check whether the attached version works.

In the attached version all child nodes of a NSObject tag are joined together 
to form the string. Normally the whole string should be identified as one node 
by the parser. But the Android parser seems to work incorrectly in this regard.

Here's the Android bug about this: 
http://code.google.com/p/android/issues/detail?id=2607

Sounds like there's no way to force coalescing of entities (unlike CDATA 
sections, which is what setCoalescing is for).

@daniel.dreibrodt looks like the attached jar file you provided did the trick!! 
Thanks!!

I commited the proper fix with r54.
