Hi Guys,

Does anybody know how to escape HTML Entities using SAX? I have been reading forums about this and it seems there's still no solution for this one.

if i have an XML with a content below:

Code: Select all

Angels & Demons

it will only return amp; Demons

Sir plusminus and other guys who know the solution, hope you can help me on my query.

Thanks!

Why "name" or "phone" can't be something with space between (for ex. "One car") or with foreign characters (for ex. "šđžćč"). Thanks

EDIT: For "space" - i removed from Person.java on line 74 code "tempString.setLength(0);" and now I can put spaces..but what about foreign characters or for example - $%&...? Tnx.

Hi, actually I perform a google product search and recieving the xml.
I'm wondering if there is no example source where somebody else does this?
Can anyone help me out, or am I entirely wrong?!
(This xml is huge and a challenge to be parsed in my opinion.)

I'm fighting with this problem for weeks now, so every help would be appreciated!
Thanks a lot!

hi dude,

Please solve my problem. i have to parse a xml file which is present in SDcard and xml file which is present on hard disk.
please kindly provide me the solution. if you have any sample code please send me on my id

my email id is shadabansu@gmail.com

I am having an issue where trying to parse XML from one of my private google calendar pages is not returning the full string. For example, the full XML string that I want to parse is:

Code: Select all

<summary type='html'>When: Wed Jun 9, 2010 1pm to 2pm&amp;nbsp;
EDT&lt;br&gt;



&lt;br&gt;Event Status: confirmed</summary>

The string that is returned however, is just:

Code: Select all

Event Status: confirmed

Dont ask ME why the line breaks are in there or the html is in there, ask Google. I have tried using regular expressions to remove all special characters and line breaks from the string but still get the same result so to me, I understand that I am not getting the full string to begin with. Anyone ever seen this before or have any ideas on how to resolve this?

Hi men,

In fact, when you parse your xml

Code: Select all

<summary type='html'>When: Wed Jun 9, 2010 1pm to 2pm&amp;nbsp;
EDT&lt;br&gt;

&lt;br&gt;Event Status: confirmed</summary>

, exactly the result will be:

Code: Select all

When: Wed Jun 9, 2010 1pm to 2pm 
EDT<br>

<br>Event Status: confirmed

. This function will know the string in tag, it can not give you

Code: Select all

Event Status: confirmed

.

Best regard,
Alex.

Thanks for the response songotho. So your thinking that there is something wrong with the way I am printing the parsed line? I am saving the variable to a string and then printing that string. Is there a better way to do it? If it is parsing the entire string in the tag and returning it to the variable, then the only thing that that leaves to be broken in the process is printing the variable. Thanks.

hi plusminus,
i ran the code but my emulator is giving an error:-
Error:Permission denied....
please help....
actually i want to make an RSS feed so i wanted to learn how to extract data from internet and then i would store it in database the retrieve for the user....is my approach right??
please help

anuj

This is a good tutorial, thanks man

What about overriding startPrefixMapping(String prefix, String uri)? When I do that, it never get's called.

Actually we have the same problem. It's a bug in SAX Parsing in which they cannot recognize HTML Entities. I hope somebody can help us.

i need help using arraylist with the parser.

here is my code. the problem is that the list that is returned contains only the last xml part i need to parse and it repeats 10 times (thats the number of different values i have to get.)

my only guess is that it adds the pointer to the object for every element in the string array (maybe this info will help)

how do i fix it?



here is how i set it to textView on screen
