Hi All,
I am trying to fetch the location and service providers value for a particular number from the xml code below

<?xml version="1.0" ?>
<knowcarrier>
<mobile>
<number>98450,98451,98452</number>
<serviceprovider>AIRTEL</serviceprovider >
<location>Karnataka</location>
</mobile>
<mobile>
<number>94450,94451,94452</number>
<serviceprovider>BSNL</serviceprovider >
<location>Karnataka</location>
</mobile>
<mobile>
<number>98440,98441,98442</number>
<serviceprovider>SPICE</serviceprovider >
<location>Karnataka</location>
</mobile>

Eg: if i am searching for the no 98451, and on successfull search, it should display only "AIRTEL","Karnataka". but i am getting all the data in the file.
can anyone plz help me.

Thanks in advance
Veekay

Re: xml parser

Hi veekay
Sorry I couldn't completely understand you ,

but i am getting all the data in the file.

Any way
These are some step for getting AIRTEL and Karnataka from your XML file: First Read complete data in Descriptor
1-> Search for 98451( you are successful as you mentioned above )
2->Search for
<serviceprovider>
I think This tag is unique across all Xml file (Now you have got AIRTEL )
3->Search for
<location>
I think This tag is unique across all Xml file (Now you have got Karnataka )
follow above three step :
If you encounter any problem , post that here

Thanks and Regard

Re: xml parser

Thanks Praveen, But how to get the value between the tag.
like in the xml parser example... what shud be written in the function

OnStartElementL( const RTagInfo& aElement, const RAttributeArray& aAttributes, TInt aErrorCode )
and
OnContentL( const TDesC8 &aBytes, TInt aErrorCode )

i am sorry if i am asking the very basics.

thanks

Re: xml parser

I made changes in OnContentL( const TDesC8 &aBytes, TInt aErrorCode )
i included few line

if(buffer->Find(_L("98452"))!=KErrNotFound )
{
aFlag = KNumberFound;

}
if(aFlag == KFetchInfo)
{
if(iNumOfDataToFetch<4)
{
AppendText( *buffer );
iNumOfDataToFetch++;
}
}

and in
OnStartElementL( const RTagInfo& aElement, const RAttributeArray& aAttributes, TInt aErrorCode )
i included

if(aFlag == KNumberFound)
{
aFlag = KFetchInfo;
}
thats all Smiling
