JPedal library in java is usually used to convert pdf to XML or HTML. However, I needed to know if we could extract data from HTML5 document and save it to XML using JPedal library API?
Is there any other possible alternative to this?
Also , I am trying to parse HTML5 document using Java and store it in XML. are there any good solutions to find just specific tags and render an XML out of them?
Please do let me know . Thank you.
There are a number of Java HTML parsers out there, but I recommend using the HTML5 parser from validator.nu available for download from here: http://about.validator.nu/htmlparser/.
Written to use the HTML5 parser algorithm by one of the main protagonists of HTML5, Henri Sivonen of Mozilla, you won't find a more reliable HTML parser and it creates a true DOM that can be manipulated using standard XML tools and queried for hyperlinks using XPath. There are examples of how to use XSLT transformations with it and how to get an XML serialization of the created DOM.

[Background Info]
We had a solution in place to use Word automation serverside to convert HTM documents into Docx, PDF or Print documents. This solution broke in the latest version of Windows Server 2012. We learned that MS does not intend on Word working in this manner and after trouble shooting with MS support Engineers we have come to the conclusion that it will never work.
[Currently]
I am currently researching potential technologies and tools that my company can use to regain this functionality. We need to be able to create Docx, PDF and print files to a local printer.
I have looked into a number of tool already and I am currently leaning towards Apache FOP this seems to handle PDF and Printing for us.
However, I'm looking for some advice and suggested tools that we could use to implement a pure Java approach. Currently our application creates HTM files with all the required information. So ideally we would like to take these HTM files and "Convert" them into Docx/XLS-FO format.
[Question]
So my question that I'm hoping you will be able to help me with.
What is the best tools that I can use to get from
HTM to Docx
HTM to PDF
Or what would be the best process for achieving this? has anyone had success finding a solution for this in the past?
Thank You
It depends on the level of control and the complexity of the source HTML. There are HTML to FO stylesheets but you might find them wanting for your specific need.
So you could use the Jericho parser to read the HTML and generate FO. Or you generate the target format directly using Apache PDFBox and Apache POI
It all boils down to the level of control you want/need
docx4j-ImportXHTML will get you from XHTML to docx. From there, you can use docx4j (or some other solution eg LibreOffice/OpenOffice) to do docx to PDF.
docx4j supports docx to XSL FO, and by default uses FOP.
I have a xml file that is on this link
http://nchc.dl.sourceforge.net/project/trialxml/options.xml
I have downloaded and parsed it successfully and also made a dynamic UI, but I have not used any of the predefined functions like getFirstChild(), getNextSibling() which makes my parser incompatible of parsing complex XML files having around 6-7 levels of menus.
Please help how to traverse a XML file,and dynamically create a UI.
Try using DOM parser, to parse your xml document
See this link for further details:

Is it a good idea? Well I have used other 3rd party Libraries like JSoup and it works great, but for this project it's different. Is it worth it to load and parse a whole document when you just want to get one item from it? Some of the html pages are simple too, so I could use String methods too. Reason is cause memory will be an issue, and it also takes some time to load the document too. When parsing XML I always use a SAX Parser because it doesn't load it in memory and it is fast. Could I use the same thing on html documents, or is there already one like this out there? So if there is a non-DOM HTML lightweight parser, that would be great too.
If the HTML is XML compliant (i.e. it's XHTML) then you can use a standard SAX parser. Here you can find a list of HTML parsers in Java to choose from: http://java-source.net/open-source/html-parsers. HotSax probably will handle all your use cases.
Which APIs in java help in extracting table metadata from a pdf, and presenting that table in a web page?
The result should be that when the source of page is viewed it will show the html code of that table.
Itext is usefull in this context
http://itextpdf.com/
I assume that, you need a PDF library for Java.
PDFBox is one of the popular libraries created to PDF manipulation and I think it is worth to look at it.
try The Metadata Extract Tool which extracts metadata from specific file types including PDF. Then you can parse the xml output with any Java XML parser. Once you're able to parse it, elements can be easily laid down in your view page.
I was looking at using iText to create both a pdf and html version of a document with RTF as a possible option. According to this question this is no longer possible with iText. Is there a library that will allow me to create a document in Java and output it as both PDF and HTML? The ability to output RTF would be nice but is not required.
As that answer to the other question states, you can just use the iText RTF Library.
I have used PD4ML to convert HTML to pdf. Even though it is a commercial app. It is very reliable and supports CSS well.
JasperReports. If you look at this package it supports export to:
pdf
html
rtf
xls
xml
You have two options to create the documents:
via iReport - a visual designer for reports
via an API, where you construct everything with Java code.
Note that even though JasperReports's main function is to create reports, it can very well create other documents, with no tabular data for example.
You could also try Docmosis since that supports the output formats provided by OpenOffice (including the ones you specified) and you can often do the job with a lot less code.
