[英]Maven: How can I have a module with same name under two different modules?
[英]How do I resolve two nodes which have the same name but under different parents?
<PublicRecords>
<USBankruptcies>
<USBanktruptcy>...<USBankruptcy>
<CourtId>...</CourtId>
<USBanktruptcy>...<USBankruptcy>
<CourtId>...</CourtId>
</USBankruptcies>
<USTaxLiens>
<USTaxLien>...<USTaxLien>
<CourtId>...</CourtId>
<USTaxLien>...<USTaxLien>
<CourtId>...</CourtId>
</USTaxLiens>
<USLegalItems>
<USLegalItem><USLegalItem>
<CourtId></CourtId>
<USLegalItem><USLegalItem>
<CourtId></CourtId>
</USLegalItems>
</PubicRecords>
我使用doc和xpath對象的組合來提取屬性和節點內容。
NodeList bp = doc.getElementsByTagName("USBankruptcy");
NodeList nl = doc.getElementsByTagName("CourtId");
long itrBP;
for (itrBP = 0; itrBP < bp.getLength(); itrBP++ )
{
Element docElement = (Element) bp.item(itrBP);
Element courtElement = (Element) nl.item(itrBP);
NodeList df = docElement.getElementsByTagName("DateFiled");
if(df.getLength() > 0)
{
dateFiled = nullIfBlank(((Element)df.item(0)).getFirstChild().getTextContent());
dateFiled = df.format(dateFiled);
}
但是,當我說獲取標簽名稱CourtID的元素時,它將獲得所有CourtID,而不僅僅是USB破產。
有沒有辦法指定父母?
我嘗試了NodeList nl = doc.getElementsByTagName(“USBankruptcies / CourtId”);
它在運行時給了我一個dom錯誤。
請在這里找到代碼:
DocumentBuilderFactory domFactory = DocumentBuilderFactory
.newInstance();
domFactory.setNamespaceAware(true);
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document doc = builder.parse("test.xml");
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xpath.compile("*//USBankruptcies/CourtId");
Object result = expr.evaluate(doc, XPathConstants.NODESET);
NodeList nodes = (NodeList) result;
for (int i = 0; i < nodes.getLength(); i++) {
System.out.println(nodes.item(i));
}
而不是在Document上調用getElementsByTagName("CourtId")
方法,而是在子元素(在您的情況下, <USBankruptcies>
元素)上調用它。
NodeList bankruptcyNodes = doc.getElementsByTagName("USBankruptcies");
Element bankruptcyElement = (Element) bankruptcyNodes.item(0);
NodeList bankruptcyCourtNodes = bankruptcyElement.getElementsByTagName("CourtId");
// etc...
