什麼是從字符串構建組的正確stringtemplate組語法？

Question

我試圖建立從String一個STGroup但抱怨無效字符和失蹤模板：

final String templates = "a(x) ::= <li>$x.fname$ $x.lname$</li>\n" + 
          "b(persons) ::= <ul>$persons:a()$</ul>\n"; 
    final STGroup grp = new STGroupString("mysource", templates, '$', '$'); 

這裏是它噴出了誤差修改：

mysource 1:10: invalid character '<' 
mysource 1:10: missing template at 'li' 
mysource 1:12: invalid character '>' 
mysource 1:13: invalid character '$' 
mysource 1:10: garbled template definition starting at 'li' 
mysource 1:14: garbled template definition starting at 'x' 
mysource 1:21: invalid character '$' 
mysource 1:23: invalid character '$' 
mysource 1:16: garbled template definition starting at 'fname' 
mysource 1:24: garbled template definition starting at 'x' 
mysource 1:31: invalid character '$' 
mysource 1:33: invalid character '<' 
mysource 1:34: invalid character '/' 
mysource 1:26: garbled template definition starting at 'lname' 
mysource 1:36: invalid character '>' 
mysource 1:34: garbled template definition starting at 'li' 
mysource 2:16: invalid character '<' 
mysource 2:16: missing template at 'ul' 
mysource 2:18: invalid character '>' 
mysource 2:19: invalid character '$' 
mysource 2:16: garbled template definition starting at 'ul' 
mysource 2:20: garbled template definition starting at 'persons' 
mysource 2:31: invalid character '$' 
mysource 2:33: invalid character '<' 
mysource 2:34: invalid character '/' 
mysource 2:36: invalid character '>' 
mysource 2:34: missing '::=' at 'ul' 
mysource 2:34: missing template at 'ul' 
mysource 2:28: redefinition of template a 
mysource 2:34: garbled template definition starting at 'ul' 

我想使用$作爲我的分隔符，能夠呈現這些模板的正確格式是什麼？

我想出了一個解決方案的程序與解答一些相關的問題和一些實驗：

STGroup grp = new STGroup('$', '$'); 
    final CompiledST templateA = grp.defineTemplate("a", "<li>$it.fname$ $it.lname$</li>"); 
    templateA.addArg(new FormalArgument("it")); 
    final CompiledST templateB = grp.defineTemplate("b", "<ul>$list:a()$</ul>"); 
    templateB.addArg(new FormalArgument("list"));
