Hi!
I'm quite new to dom4j and encounter two problems:
1. I want to parse a xml-file, make some changes and finanally write it back
to disk. By default dom4j removes all entity declarations as well as the
entity references. My xml-file looks like that:
<?xml version="1.0"?>
<!DOCTYPE config [
<!ENTITY listserverConfig SYSTEM "file:./james-listmanager.xml">
<!ENTITY listserverStores SYSTEM "file:./james-liststores.xml">
<!ENTITY fetchmailConfig SYSTEM "file:./james-fetchmail.xml">
]>
...
...
...
&listmanager
Prevent dom4j from removing the declarations seems quite simple by just
adding this to the source code:
reader.setIncludeInternalDTDDeclarations(true);
But the entity references are still expanded. First I though it might be a
good solution to disable the feature "external-general-entities". But now
the entity reference is removed completely when I write back the file :-(
As a consequence my solution now looks like that but it seems quite fussily:
DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
dbf.setExpandEntityReferences(false);
documentBuilder = dbf.newDocumentBuilder();
// create SAX reader in order to prevent removing
entity-declarations
reader.setIncludeInternalDTDDeclarations(true);
// get DOCType with entity-declarations
DocType = reader.read(xmlFile).getDocType();
// create dom4j document
DOMDocument = documentBuilder.parse(xmlFile);
document = DomReader.read(DOMDocument);
// insert DocumentType with entity-declarations
document.setDocType(DocType);
and finally the code for writing back the tree:
fileWriter = new FileWriter(fileName);
xmlWriter = new XMLWriter(fileWriter,customFormat);
xmlWriter.setResolveEntityRefs(false);
xmlWriter.write(document);
xmlWriter.flush();
xmlWriter.close();
Perhaps there is a nicer solution?!?
2. I want to add an node between two COMMENT-nodes but when I use the method
myelement.elements() the returned List only contains the "important"
(meaning the non-comment)
nodes. Therefore I cant't use the List to insert the node between two
comments. (or even remove any comment). Is there an solution for this
problem?
Thanks!!
