Hi Glenn,
What happens if you print the Document you get back from SAXSVGDocumentFactory?
I suspect that something in your code is deleting the text content. The code you are using is essentially the same as the code used internally.
Finally on the last point of modifying the document before it is displayed, you can register a listener for the SVGLoad event which would allow you to modify the document before the document is displayed. However the two should be essentially identical.

I've just encountered another challenge in batik. I create a SVGDocument using this code I found on the Batik homepages:
String parser = XMLResourceDescriptor.getXMLParserClassName(); SAXSVGDocumentFactory docFactory = new SAXSVGDocumentFactory(parser); svgDocument = (SVGDocument) docFactory.createDocument(f.toURL().toString());
And I use this (very simplified) SVG file:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd";>
<svg width="260.0" height="450.0" xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns="http://www.w3.org/2000/svg";>
<rect x="20.0" y="20.0" fill="#b04c7e" width="75.0" height="95.0" stroke="none"/>
<text x="40.0" y="40.0" fill="#ffdd22" style="font-family:arial;font-weight:bold">###TITLE###</text>
</svg>
When I now use this code:
svgCanvas.setSVGDocument(svgDocument);
What is drawn on the JSVGCanvas does not include the ###TITLE### text. Also, when I use this code:
svgCanvas.getSVGDocument().getDocumentElement()
and print the contents of the SVGDocument (using a proprietary XML output class) I get this output:
<svg contentScriptType="text/ecmascript" width="260.0" xmlns:xlink="http://www.w3.org/1999/xlink"; zoomAndPan="magnify" contentStyleType="text/css" height="450.0" preserveAspectRatio="xMidYMid meet" xmlns="http://www.w3.org/2000/svg"; version="1.0">
<rect x="20.0" y="20.0" fill="#b04c7e" width="75.0" height="95.0" stroke="none"/>
<text fill="#ffdd22" x="40.0" y="40.0" style="font-family:arial;font-weight:bold"/>
</svg>
As you can see, the text element has been drastically cut down.
When I use the JSVGCanvas itself to read the file by this code:
svgCanvas.setURI(f.toURL().toString());
The graphical output includes the text and the XML output looks like this:
<svg contentScriptType="text/ecmascript" width="260.0" xmlns:xlink="http://www.w3.org/1999/xlink"; zoomAndPan="magnify" contentStyleType="text/css" height="450.0" preserveAspectRatio="xMidYMid meet" xmlns="http://www.w3.org/2000/svg"; version="1.0">
<rect x="20.0" y="20.0" fill="#b04c7e" width="75.0" height="95.0" stroke="none"/>
<text fill="#ffdd22" x="40.0" y="40.0" style="font-family:arial;font-weight:bold">###TITLE###</text>
</svg>
As you can see, the text is now as it should be.
How can I read the SVG file into an SVGDocument while still retaining the text element?
(I want to read the SVG file into a SVGDocument and replace the ###TITLE### with a user defined title. Using the SVGDocument itself until it's ready to be drawn is more efficient than using JSVGCanvas every time since JSVGCanvas renders the SVG each time. I only want to render it when all replacements are done.)
