Hello.
The basic jist is how to render HTML within a table structure of a PDF,
where the HTML is embedded in an XML file and parsed via SAXmyHandler.
I'm posting this question to
1)check if someone's already done this
or
2)get some validation that I'm on the write track.
I'll preface the question by saying I'm not as experienced with XML and
the parsers as I would like to be. My code is built off the Romeo and
Juliet example.
I'm parsing the xml file via these calls.
SAXParser parser = SAXParserFactory.newInstance
().newSAXParser();
parser.parse("data.xml", new
testArchiveMergeBO().getXmlHandler(document));
I have written a tagmap.xml and implemented it in a class that extends
TagMap. My tag class is initialized in a class MyHandler (extending
SAXmyHandler) - same as the example. Here's a portion of that tagmap.xml
file
<tag name="table" alias="DATA_T">
<attribute name="columns" value="2" />
<attribute name="align" value="Left" />
<attribute name="width" value="100%" />
<attribute name="widths" value="50;50" />
<attribute name="cellpadding" value="1" />
<attribute name="cellspacing" value="0" />
<attribute name="offset" value="0" />
<attribute name="bordercolor" value="#000000"/>
<attribute name="borderwidth" value="0.2"/>
<attribute name="left" value="false"/>
<attribute name="right" value="false"/>
<attribute name="top" value="false"/>
<attribute name="bottom" value="true"/>
</tag>
<tag name="row" alias="DATA_R">
<attribute name="horizontalalign" value="Left" />
<attribute name="verticalalign" value="Middle" />
</tag>
<tag name="cell" alias="DATA_C">
<attribute name="horizontalalign" value="Left" />
<attribute name="verticalalign" value="Middle" />
<attribute name="bordercolor" value="#000000"/>
<attribute name="borderwidth" value="0.2"/>
<atttibute name="leading" value="1"/>
<attribute name="left" value="false"/>
<attribute name="right" value="false"/>
<attribute name="top" value="false"/>
<attribute name="bottom" value="true"/>
</tag>
<tag name="paragraph" alias="P_BOLD">
<attribute name="size" value="8" />
<attribute name="fontstyle" value="bold"/>
<attribute name="leading" value="10"/>
</tag>
<tag name="paragraph" alias="P_REG">
<attribute name="size" value="8" />
<attribute name="leading" value="10"/>
</tag>
All the same here, as in the Romeo and Juliet example.....
However, my data.xml contains embedded HTML
<DATA_T>
<DATA_R>
<DATA_C><P_REG>Some generic rich text field</P_REG
></DATA_C>
<DATA_C>
<P_BOLD>
<hr/><b>this is bold text</b><br></br><font color=
"red">Red Text</font>
</P_BOLD>
</DATA_C>
</DATA_R>
</DATA_T>
The application has about 100 different pages, so I chose the parser
method (vs building the document and adding each element in code) because
I wanted to have a consistent look/feel that the tagmap would generate.
However, had I chose to build the document by hand in code, I would have
been able to use the utility class HtmlWorker that will render the desired
HTML inside a table (quite easily might I add).
StyleSheet st = new StyleSheet();
String html = new String("<hr/><b>this is bold
text</b><br></br><font color="red">Red Text</font>");
StringReader sr = new StringReader(html);
ArrayList p = HTMLWorker.parseToList(sr, st);
for (int k=0;k<arrayList.size();++k) {
document.add((Element) arrayList.get(k));
}
Should I add the desired/allowable HTML tags (i.e. <b>,<hr><font>) in the
tagmap? or should I capture those tag inside the startElement and
endElement overridden methods of MyHandler (and do what HTMLWorker does)?
or is there another means to solve this.
Just asking before I delve too far into it.
Thanks in advance,
Scott

It's still not supported.

All you have to do is to buy the crionics product, it's not in any way
related to iText and I don't even know what's the relevance of it in the
iText mailing list.

iText doesn't support rich text.
