VTD-XML data analysis performance (critical speed factor). Request feedback / comments

Question

I'm going to use VTD-XML (found at http://vtd-xml.sourceforge.net/ ), but I'm interested in getting real-time feedback from anyone who has used the library and has any comments.

There are tests in the URL ( http://vtd-xml.sourceforge.net/ ), but if someone used VTD-XML and has comments on it, I would like to hear them. Speed ​​is the deciding factor in the application, and comments after real use by developers are what I'm looking for.

Hi,

Answer 1

VTD-XML performance has been measured by a number of sources, some of which are listed below.

• This report ( https://code.ai.techfak.uni-bielefeld.de/trac/xcf/wiki/Evaluation ) contains numbers that measure parsing performance / xpath compared to XOM, binary XML, SAX and DOM

• Also xmlbench (search the web as a keyword) will lead you to an open source project dedicated to the XML parsing performance site

• The VTD-XML website also has a number of sample reports (there will be updates soon).

  4. here is an article by some researchers from Portugal published in 2013. http://sdiwc.net/digital-library/web-admin/upload-pdf/0 0000466.pdf

Answer 2

VTD-XML XPath. DOM XPath , 20 17 . SAX, SAX XPaths, " " . VTD-XML, xml 20 !

Answer 3

I found that VTD-XML was really faster for parsing and XPAth, but I found that XPath uses a lot more memory than the DOM. In addition, Java version 2.10 simply did not work with attributes and XPath, so that was not the case.
