i want to get the names of the first two Service Authors.
i have the following XML example:
<ServiceSchema:id>10</ServiceSchema:id>
<ServiceSchema:name>Service 10</ServiceSchema:name>
<ServiceSchema:authorInfos>
<ServiceSchema:authorInfo>
<ServiceSchema:id>1</ServiceSchema:id>
<ServiceSchema:name>Service Author 1</ServiceSchema:name>
<ServiceSchema:authorInfo>
<ServiceSchema:authorInfo>
<ServiceSchema:id>2</ServiceSchema:id>
<ServiceSchema:name>Service Author 2</ServiceSchema:name>
<ServiceSchema:authorInfo>
</ServiceSchema:authorInfos>
<ServiceSchema:requirements>
<ServiceSchema:requirement>
<ServiceSchema:id>1</ServiceSchema:id>
<ServiceSchema:name>Requirement 1</ServiceSchema:name>
<ServiceSchema:authorInfos>
<ServiceSchema:authorInfo>
<ServiceSchema:id>5</ServiceSchema:id>
<ServiceSchema:name> Requirement Author 5</ServiceSchema:name>
<ServiceSchema:authorInfo>
</ServiceSchema:authorInfos>
</ServiceSchema:requirement>
.....
I can get all name nodes with the following code:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource inputSource = new InputSource(new ByteArrayInputStream (xml.getBytes("utf-8")));
Document xmldocument = db.parse(inputSource);
NodeList nodeList = xmldocument.getElementsByTagNameNS("*", "name");
But i don't know how to get only the names of the outer authors.
Thank you.
Update:
What I am trying to do completely is: I search different xml files for different nodes. The xml file above was meant as an example.
For example:
searchElementsXml = new String[]{"name", "id", "version", "description", "keywords", "authorInfos.authorInfo.name", "status"};
I have some fields where many values can occur. Like the author info.
So i need something like:
NodeList nodes = doc.getElementsByTagName("ServiceSchema:authorInfos:authorinfo:name");
is there a good solution out there?
如果我正确理解了您想要什么,我建议您获取所有作者信息 (ServiceSchema:authorInfo),然后获取每个 authorInfo 的名称节点。
Is your XML is proper i cant see that ServiceSchema:authorInfo tag is closing
Can you please update the output what you are looking . to get the authorsInfos you can use the below code NodeList nodes = doc.getElementsByTagName("ServiceSchema:authorInfos");
Her is the detail execution code
File fXmlFile = new File("/Users/Downloads/test.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
NodeList nodes = doc.getElementsByTagName("ServiceSchema:authorInfos");
for (int temp = 0; temp < nodes.getLength(); temp++) {
Node nNode = nodes.item(temp);
System.out.println(" Current Author Element :" + nNode.getNodeName());
if (nNode.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) nNode;
System.out.println("Author Info Name : " + eElement.getElementsByTagName("ServiceSchema:authorInfo").getLength());
}
}
I ended up using xpath as suggested by others. Works pretty well-
