Read "%" sign from xml in iphone

Question

I have searched for my prob and found the various solution on web like :

Using the British pound sign in an XML feed to be read by an iPhone

NOt able to parse "&"

Special Characters in NSString from HTML

This and here also

but it is not fruitful for me as after reading xml I am saving it in my DB.

Here is the xml :

<root>
    −<Discounts>
        <DiscountID>1</DiscountID>
        <Title>WeekEnd Offers</Title>
        <Description>Offer upto 50%</Description>
        <SalePrice>50</SalePrice>
        <RegularPrice>100</RegularPrice>
        <CreatedDate>11/14/2011</CreatedDate>
        <LastModifiedDate>11/14/2011</LastModifiedDate>
        <Status>1</Status>
        <PhotoPath>/photos/documents/coupzila/hiteshi-logo.png</PhotoPath>
    </Discounts>
</root>

m getting the description in string as :

  NSString * strDescription = [item.mdictXMLTagsData valueForKey:@"Description"];

    NSLog(@"String in description is : ",strDescription);

but the description field is getting null in console and i cant store it in my DB.

pls suggest how can I read and store special characters to my DB.

One more thing i came to know that &#37 is the keyword to read % sign but i dont know how n where to apply this.

pls help!!!

EDIT : my current code.

Edited :- Hope u r Initializing the currentParsedCharacter...

This is not the exact code for u... but it should be similar... try it out or else provide code for what u r trying do that we can help in a better way.

    if(self == [super init]){
