How to add multiple arguments into XPath and replace %s to param

问题

我有一个字符串(例如):

xpath = //tagname[text()='param1']/tagname[text()='param2']/tagname[text()='param3']

变量param可以从1增加到n(param1,param2,param3 .... paramN)

我想要构建一个函数,将多个参数添加到xpath中,并且我必须在Java中使用String格式来将多个值放入xpath中,但不知道如何将param替换为%s并使用String格式来放入多个参数。

我该如何构建一个将param替换为%s的函数?

非常感谢。

英文:

I have a string (e.g):

xpath = //tagname[text()='param1']/tagname[text()='param2']/tagname[text()='param3']

var param can increase from 1 => n (param1, param2, param3 .... paramN)

I want to build a function to add multiple arguments into xpath and I have to use String format in Java to put multiple value into xpath and do not know how to replace param to %s and use String format put multiple arguments.

Thank you so much.

你可以在[tag:xpath]中用不同的变量替换,如下所示:

  • 代码块:

    String str1 = "stringA";
    String str2 = "stringB";
    String str3 = "stringC";
    System.out.println("//tagname[text()='" + str1 + "']/tagname[text()='" + str2 + "']/tagname[text()='" + str3 + "']");
    
  • 控制台输出:

    //tagname[text()='stringA']/tagname[text()='stringB']/tagname[text()='stringC']
    
英文:

You can different variables to be replaced within the [tag:xpath] as follows:

  • Code Block:

    String str1 = "stringA";
    String str2 = "stringB";
    String str3 = "stringC";
    System.out.println("//tagname[text()='" +str1+ "']/tagname[text()='" +str2+ "']/tagname[text()='" +str3+ "']");
    
  • Console output:

    //tagname[text()='stringA']/tagname[text()='stringB']/tagname[text()='stringC']

以下是翻译好的部分:

假设xpath是“//tagname[text()='param']/tagname[text()='param']/tagname[text()='param']”而param是需要替换的模式。

public static String replaceValue(String xpath, String... params) {
    for (String replacement : params) {
        xpath = xpath.replaceFirst("param", replacement);
    }
    return xpath;
}

您还可以在xpath中使用正则表达式模式,而不是'param'关键字。

英文:

Suppose xpath is "//tagname[text()='param']/tagname[text()='param']/tagname[text()='param']" and param is pattern that need to be replaced.

public static String replaceValue(String xpath , String...params){
	for(String replacement : params){
		xpath = xpath.replaceFirst("param",replacement);
	}
	return xpath;
}

you also can use a regex pattern instead of 'param' keyword in xpath.
