命名空间和 xpath [英] namespace and xpath

问题描述

图书馆 xades4j .代码如下:

 静态 {尝试 {DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();dbf.setNamespaceAware(true);db = dbf.newDocumentBuilder();} catch (ParserConfigurationException ex) {//... ...}}文档文档 = 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) 新 XadesTSigningProfile(keyProvider).withTimeStampTokenProvider(TestTimeStampTokenProvider.class).withAlgorithmsProviderEx(ExclusiveC14nForTimeStampsAlgorithmsProvider.class).newSigner();xadesSigner.sign(new SignedDataObjects(obj1), doc);

如果在 XML 文档中没有定义任何命名空间并且 getxPath() 返回路径喜欢

<块引用>

"/文档/组件",

签名生成和验证都运行良好.

然后，我将命名空间添加到 xml 文件中:

<块引用>

<文档 xmlns="ff:kk">

并将getxPath()的返回值改为

<块引用>

"/ff:kk:文档/ff:kk:组件"

签名生成时抛出异常

<块引用>

前缀必须解析为命名空间:ff:kk

似乎我必须在签名生成期间向代码中添加类似 xpath.setNamespaceContext(javax.xml.namespace.NamespaceContext) 的内容.

但是我在哪里可以做到.

谢谢

解决方案

在命名空间声明中，您声明该元素的默认命名空间是ff:kk"，而不是前缀.在 xpath 表达式中，您将其用作未定义的前缀.

您可能希望在顶部元素上使用 xmlns:prefix="namespace" 之类的东西，然后在 xpath 上使用 /prefix:Document/prefix:component 之类的东西.

Libarary xades4j . code as following:

  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);

if there is not any namespace defined in XML document and the getxPath() return path likes

"/Document/component" ,

the both the signature generation and verification work well .

and then , I add the namespace into the xml file :

<Document xmlns="ff:kk">

and change the return value of getxPath() to

"/ff:kk:Document/ff:kk:component"

Exceptions are threw out when signature generation

Prefix must resolve to a namespace: ff:kk

it seems that i have to add something like xpath.setNamespaceContext(javax.xml.namespace.NamespaceContext) into the code during signature generation.

but where can I do it .

thanks

解决方案

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.

这篇关于命名空间和 xpath的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
