--------------------------------------
Hello
in conjunction with preflight like this
{{<dependency>}}
{{<groupId>org.apache.pdfbox</groupId>}}
{{<artifactId>preflight</artifactId>}}
{{<version>3.0.5</version>}}
{{<scope>system</scope>}}
{{<systemPath>${project.basedir}/preflight-app-3.0.5-20250322.104829-67.jar</systemPath>}}
{{</dependency>}}
{{<dependency>}}
{{<groupId>org.apache.pdfbox</groupId>}}
{{<artifactId>pdfbox</artifactId>}}
{{<version>3.0.5</version>}}
{{<scope>system</scope>}}
{{<systemPath>${project.basedir}/pdfbox-app-3.0.5-20250322.104829-66.jar</systemPath>}}
{{</dependency>}}
I can confirm it works, thanks a lot!
I assume -app are with dependencies, what I previously only knew as "shaded"?
FYI I really only need this functionality in the very outskirts of
mustangproject.org, until your 3.0.5 release I consider the following xpath
based workaround:
{{InputStream exportXMPMetadata = metadata.exportXMPMetadata();}}
{{DocumentBuilderFactory builderFactory =
DocumentBuilderFactory.newInstance();}}
{{builderFactory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);}}
{{builderFactory.setNamespaceAware(true);}}
{{DocumentBuilder builder = builderFactory.newDocumentBuilder();}}
{{Document xmlDocument = builder.parse(exportXMPMetadata);}}
{{XPath xPath = XPathFactory.newInstance().newXPath();}}
{{xPath.setNamespaceContext(new NamespaceContext() {}}
{{@Override}}
{{public String getNamespaceURI(String prefix) {}}
{{if ("pdfaid".equals(prefix)) {}}
{{return "http://www.aiim.org/pdfa/ns/id/";}}
{{}}}
{{return null;}}
{{}}}
{{@Override}}
{{public String getPrefix(String namespaceURI) {}}
{{// This should be implemented but I'm lazy and this sample works without it}}
{{return null;}}
{{}}}
{{@Override}}
{{public Iterator getPrefixes(String namespaceURI) {}}
{{// This should be implemented but I'm lazy and this sample works without it}}
{{return null;}}
{{}}}
{{});}}
{{String expression = "//@pdfaid:part";}}
{{NodeList childNodes = (NodeList)
xPath.compile(expression).evaluate(xmlDocument, XPathConstants.NODESET);}}
{{for (int n = childNodes.getLength() - 1; n >= 0; n--) {}}
{{Node child = childNodes.item(n);}}
{{short nodeType = child.getNodeType();}}
{{if (nodeType == Node.ELEMENT_NODE) {}}
{{// clean(child);}}
{{}}}
{{else if (nodeType == Node.ATTRIBUTE_NODE) {}}
{{String trimmedNodeVal = child.getNodeValue().trim();}}
{{System.out.println("PDF/A version"+trimmedNodeVal);}}
{{//child.setNodeValue(trimmedNodeVal);}}
{{} else if (nodeType == Node.COMMENT_NODE) {}}
{{// node.removeChild(child);}}
{{}}}
