Question

我正在使用XMLQuire生成补丁以获取补丁。但总是返回空值：

使用的Xpath：

//dft:enviNFe/dft:NFe/Signature/SignedInfo/Reference/DigestValue

那个有效：

//k:enviNFe/k:NFe/k:infNFe/k:ide/k:tpAmb

使用的功能：

XPath xPath = XPath.newInstance(SignatureValue);
xPath.addNamespace("dft", d.getRootElement().getNamespaceURI());
Element node = (Element) xPath.selectSingleNode(d.getRootElement());

XML：

Answer 1

根元素位于命名空间xmlns="http://www.portalfiscal.inf.br/nfe"及其大多数子节点中。

Signature元素位于命名空间mlns="http://www.w3.org/2000/09/xmldsig#"及其所有子节点中。

因此，您的XPath中需要2个名称空间......

和...你需要使用JDOM-2的新XPath API，而不是旧的。所以，做：

Namespace sig = Namespace.getNamespace("sig", "http://www.w3.org/2000/09/xmldsig#");
Namespace nfe = Namespace.getNamespace("nfe", "http://www.portalfiscal.inf.br/nfe");

XPathFactory xfac = XPathFactory.instance();
XPathExpression<Element> digest = xfac.compile(
    "/nfe:enviNFe/nfe:NFe/sig:Signature/sig:SignedInfo/sig:Reference/sig:DigestValue",
    Filters.element(), null, sig, nfe);

String digestValue = digest.evaluateFirst().value();

请参阅documentation for compile.

而且，当您发布问题时，请让您的XML更易于阅读。
