I’ve been running into problem after problem trying to use the a third party

  • 0

I’ve been running into problem after problem trying to use the a third party HTML editor to do what (I hoped) was a simple operation. Because of these problems, I’m looking for recommendations for an alternative HTML parser I could use to perform the operations.

Here’s my situation, I have span tags in my html (with an ID attribute to identify them) and I simply want to replace their contents based on an update in another area of my client. For example:

<html>     <body>         <p>Hello <span id='1'>name</span> you are <span id='2'>age</span></p>     </body> </html>

I’ve been trying to use the HTMLDocument class in javax.swing.text like this:

Element e; e = doc.getElement(document.getDefaultRootElement(), Attribute.ID, '1'); document.setInnerHTML(element, 'John'); e = doc.getElement(document.getDefaultRootElement(), Attribute.ID, '2'); document.setInnerHTML(element, '99');

but the element returned is a leaf element and won’t allow the innerHTML to be set. Unfortunately, the document, reader & parser are all supplied by a 3rd party & so I can’t really modify it.

So, what I was hoping for was that someone else has had a similar problem and could recommend an alternative library to do this?

Thanks in advance, B.

  1. Can you really not accomplish that with java.swing.text.HTMLDocument?

    I have never tried this but reading through the API something along the line of

    document.replace(e.getStartOffset(), e.getEndOffset()-e.getStartOffset(), 'John', null)

    instead of using setInnerHtml() could work.
