如何使用Java替换xml标记中的所有冒号？

我想替换所有标记值中的冒号。但是，我的xml有名称空间后缀。如何使用Java安全地替换它

e、 g

我想要这样的结果：

<ns:shop>ABC Adress 1</ns:shop>
   <ns:person>John Lee</ns:person>
<ns:shop>DEF: Adress 2</ns:shop>
   <ns:person>Susan Lee</ns:person>

您是否尝试过以下特定标签的替换

public class replacetagcontent {
    static String inputFile = "C:/temp/shop.xml";
    static String outputFile = "C:/temp/shop_modified.xml";    

    public static void main(String[] args) throws Exception {         
        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        documentBuilderFactory.setNamespaceAware(true);
        DocumentBuilder builder = documentBuilderFactory.newDocumentBuilder();
        Document doc = builder.parse(inputFile);        

        // locate the node(s)
        XPath xpath = XPathFactory.newInstance().newXPath();
        xpath.setNamespaceContext(new MyNamespaceContext());
        NodeList shp_nodes = (NodeList)xpath.evaluate("//ns:shop", doc, XPathConstants.NODESET);
        NodeList pers_nodes = (NodeList)xpath.evaluate("//ns:person", doc, XPathConstants.NODESET);

        // make the change
        for (int i = 0; i < shp_nodes.getLength(); i++) {
            String name_value = shp_nodes.item(i).getTextContent();
            shp_nodes.item(i).setTextContent(name_value.replace(":",""));
            String title_value = pers_nodes.item(i).getTextContent();
            pers_nodes.item(i).setTextContent(title_value.replace(":",""));
        }

        // save the result
        Transformer xformer = TransformerFactory.newInstance().newTransformer();
        xformer.transform(new DOMSource(doc), new StreamResult(new File(outputFile)));
    }

    private static class MyNamespaceContext implements NamespaceContext {
        public String getNamespaceURI(String prefix) {
            if("ns".equals(prefix)) {
                return "http://www.example.org/schema";
            }
            return null;
        }
        public String getPrefix(String namespaceURI) {
            return null;
        }
        public Iterator getPrefixes(String namespaceURI) {
            return null;
        }
    } 
}

解析xml并将：替换为空字符串。使用xml API是这里的关键-不要将其视为一个大字符串。。使用SAX或StAX-他们将为您遍历文档，您所需要做的只是替换。如其他人所述，使用XML解析器。用等号替换冒号的快速脏解决方案：String xml=your xml here.replacens:，ns；。替换“：”，“=”。替换项；，ns:；但问题是名称空间的后缀可能是ns1:ns2:，很难使用脏的解决方案。任何解决方案都可以通过正则表达式替换它？

public class replacetagcontent {
    static String inputFile = "C:/temp/shop.xml";
    static String outputFile = "C:/temp/shop_modified.xml";    

    public static void main(String[] args) throws Exception {         
        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        documentBuilderFactory.setNamespaceAware(true);
        DocumentBuilder builder = documentBuilderFactory.newDocumentBuilder();
        Document doc = builder.parse(inputFile);        

        // locate the node(s)
        XPath xpath = XPathFactory.newInstance().newXPath();
        xpath.setNamespaceContext(new MyNamespaceContext());
        NodeList shp_nodes = (NodeList)xpath.evaluate("//ns:shop", doc, XPathConstants.NODESET);
        NodeList pers_nodes = (NodeList)xpath.evaluate("//ns:person", doc, XPathConstants.NODESET);

        // make the change
        for (int i = 0; i < shp_nodes.getLength(); i++) {
            String name_value = shp_nodes.item(i).getTextContent();
            shp_nodes.item(i).setTextContent(name_value.replace(":",""));
            String title_value = pers_nodes.item(i).getTextContent();
            pers_nodes.item(i).setTextContent(title_value.replace(":",""));
        }

        // save the result
        Transformer xformer = TransformerFactory.newInstance().newTransformer();
        xformer.transform(new DOMSource(doc), new StreamResult(new File(outputFile)));
    }

    private static class MyNamespaceContext implements NamespaceContext {
        public String getNamespaceURI(String prefix) {
            if("ns".equals(prefix)) {
                return "http://www.example.org/schema";
            }
            return null;
        }
        public String getPrefix(String namespaceURI) {
            return null;
        }
        public Iterator getPrefixes(String namespaceURI) {
            return null;
        }
    }
