我正在尝试获取所有模板参数-{{}}中的参数名称。例如,对于此模板:
在{{toy}}之后追逐的{{pet}}
我想得到“宠物”和“玩具”
我只能使用samskivert/jmustache library,所以不能使用其他的胡子库。
有没有办法用jmustache做到这一点,这样我就不必用正则表达式解析字符串了?

Mustache.Visitor
用于在不执行模板的情况下访问模板中的标签
示例:
List<String> vars = new ArrayList<>();
Template tmpl = ... // compile your template
tmpl.visit(new Mustache.Visitor() {
// I assume you don't care about the raw text or include directives
public void visitText(String text) {}
// You do care about variables, per your example
public void visitVariable(String name) {vars.add("Variable: " + name); }
// Also makes sense to visit nested templates.
public boolean visitInclude(String name) { vars.add("Include: " + name); return true; }
// I assume you also care about sections and inverted sections
public boolean visitSection(String name) { vars.add("Section: " + name); return true; }
public boolean visitInvertedSection(String name) { vars.add("Inverted Section: " + name); return true; }
});
Visitor
从jmustache
版本1.15开始可用:
