I have just modified the LocalFileFormatTarget to have some buffering. It should be faster now.

I'm not sure if it is the same problem I had, but writing the DOM tree directly to disk is pretty slow, because it writes a few characters at a time. I think there is a bug already filed against it. I'm planning on working on a fix to this, but just have not had the time. As a workaround you can write the DOM tree to memory using the MemBufFormatTarget class, and then write that buffer to disk. Here is snippet: MemBufFormatTarget *myFormTarget = new MemBufFormatTarget(); theSerializer->writeNode(myFormTarget, *doc); XMLPlatformUtils::writeBufferToFile(xmlFile, myFormTarget->getLen(), myFormTarget->getRawBuffer()); XMLPlatformUtils::closeFile(xmlFile); delete myFormTarget; > -----Original Message----- > From: Dave Hoffer [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, November 19, 2002 2:58 PM > To: [EMAIL PROTECTED] > Subject: How can I write a DOMDocument faster? > > > I am using the following code to write a DOMDocument to disk. > It is taking a very long time to write (a 13KB file is > taking about 2.5 minutes) and it is driving my hard drive > crazy (it is constantly doing something). > > I obviously am doing something wrong here, can someone point > me in the right direction? > > LocalFileFormatTarget* pXMLFormatTarget; > > DOMImplementation* pDOMImplementation = > DOMImplementationRegistry::getDOMImplementation(L"LS"); > if (!pDOMImplementation) > return false; > > DOMWriter* pDOMWriter = > ((DOMImplementationLS*)pDOMImplementation)->createDOMWriter(); > if (!pDOMWriter) > return false; > > pXMLFormatTarget = new LocalFileFormatTarget( m_strTargetSpec ); > > if (!(pDOMWriter->writeNode(pXMLFormatTarget, *pDomDocument))) > return false; > > pDOMWriter->release(); > > -dh > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
