Trying to get the XML content without spaces with SAX2

[neisan]

Hi there,

I'm trying for a while to obtain the XML content of a file without spaces.

I have a XML file with the following content:

<script>

<command>

<createDocument>

<name>MyDocument</name>
<type>Text</type>

</createDocument>

</command>

<command>

<createFile>

<name>MyFile</name>
<type>File</type>

</createFile>

</command>

</script>

It happens that I need to obtain the name and type values from the XML but I'm getting the content with white spaces. Here is the code I'm trying to use:

void MySAX2Handler::startElement(const   XMLCh* const    uri,
                            const   XMLCh* const    localname,
                            const   XMLCh* const    qname,
                            const   Attributes&     attrs)
{
    outStream.clear();
    char* message = XMLString::transcode(localname);
    std::cout << "I saw element: "<< message <<  std::endl;
    XMLString::release(&message);
 
}
 
void MySAX2Handler::fatalError(const SAXParseException& exception)
{
    char* message = XMLString::transcode(exception.getMessage());
    std::cout << "Fatal Error: " << message
         << " at line: " << exception.getLineNumber()
         << std::endl;
}
 
void MySAX2Handler::characters(const XMLCh* const chars, const unsigned int length)
{
    char* message = XMLString::transcode(chars);
    std::cout << "Characters: " << message << " Lenght: " << length << std::endl;
    if (XMLString::compareIString(chars,XMLUni::fgZeroLenString) != 0) {
      outStream << message;
    }
    XMLString::release(&message);
}
 
void MySAX2Handler::endElement(const XMLCh* const uri, const XMLCh* const localname, const XMLCh* const qname)
{
      std::cout << "EndElement - OutStream: " << outStream.str() << std::endl;
}

But I'm still getting the outStream value from the endElement with white spaces.
I would really appreciate if you can help me to solve this problem.

Thank you.

Not really familiar with SAX2.

You should see the whitespace when you output the message here correct?

std::cout << "Characters: " << message << " Lenght: " << length << std::endl;
 

You should be able to replace the whitespace like so:

message = message.replaceAll("\s+", " ");
 

Note, this does not get rid of all whitespace, but adds in a single space where there used to be multiple spaces, newlines, tabs, etc..
