1. | On what browsers and operating systems WebHelp has tested extensively?
| We tested it with versions of most browsers including Firefox 3.x+, IE 7+, Chrome, Safari, and iPod/iPhone. The JavaScript codes are mostly jquery plugins, so you’d want to check the jquery support matrix for details.
2. | Apart from this demo, where can I find other demos or production deployments of WebHelp?
| There are four production deployments provided in WebHelp wiki currently.
3. | When building the webhelp output, I'm getting the following error. What's the reason for this?
    [xslt] : Warning! file:/C:/Users/kasun/docbook-xsl-1.77.0/xhtml/autoidx.xsl:
                line 596: Attribute 'href' outside of element.

                line 596: Attribute 'href' outside of element.

| This happens if you haven't done the step 3 and 4 of webhelp build guide "Generating webhelp output" in the documentation. Basically, you need to correctly set the following folder paths.
    xslt-processor-classpath=/usr/share/java/saxon-6.5.5.jar
    xercesImpl.jar=/usr/share/java/xercesImpl.jar
    xml-apis.jar=/usr/share/java/xml-apis.jar
4. | Does WebHelp Indexer can index HTML transformation as well?
| Yes, WebHelp supports HTML transformations as well in addition to XHTML.
5. | I need more information about webhelp-indexer. Where can I find it?
| The DocBook Webhelp Indexer is based on the HTMLSearch plugin for DITA. See HTMLSearch documentation for more information.
