命名空间和XPath(namespace and xpath)

2019-10-17 11:32发布

Libarary xades4j。 代码如下:

  static {
            try {
                DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
                dbf.setNamespaceAware(true);
                db = dbf.newDocumentBuilder();
            } catch (ParserConfigurationException ex) {
                 // ... ... 
            }
        }


Document doc = db.getNewDocument();          
DataObjectDesc obj1 = new DataObjectReference(
"file:///E:/doctosign/forxpath/ori_message.xml")
.withCommitmentType(getCommitmentType())
.withTransform(new     CanonicalXMLWithoutComments()) 
.withTransform(XPath2Filter.intersect(getxPath())) 
.withDataObjectTimeStamp( );

XadesSigner xadesSigner = (XadesSigner) new XadesTSigningProfile(keyProvider)
.withTimeStampTokenProvider(TestTimeStampTokenProvider.class)    
.withAlgorithmsProviderEx(ExclusiveC14nForTimeStampsAlgorithmsProvider.class)
.newSigner();

xadesSigner.sign(new SignedDataObjects(obj1),  doc);

如果没有XML文档中定义的任何名称空间和getxPath()的返回路径喜欢

“/文档/组分”,

在签名生成和验证都运行良好。

然后,我添加了命名空间到XML文件:

<Document xmlns="ff:kk"> 

并改变getxPath)的返回值(以

“/ FF:KK:文档/ FF:KK:组分”

异常被抛出时,签名生成

前缀必须解决一个命名空间:FF:KK

看来我要签名生成过程中添加类似xpath.setNamespaceContext(javax.xml.namespace.NamespaceContext)到代码。

但我在哪里可以做到这一点。

谢谢

Answer 1:

On the namespace declaration you're stating that de default namespace for that element is "ff:kk", not the prefix. On the xpath expression you're using it as a prefix, which is not defined.

You probably want something like xmlns:prefix="namespace" on the top element and then /prefix:Document/prefix:component on the xpath.
