Question

我试图在ant文件中使用正则表达式（使用replaceregexp标签）来替换java类中的特定字符串（这不是常量）时，我一直在努力，例如：
将V2_0_0替换为V1_0_0 在：

public void doSomething() {
    return "xxxxxxxV1_0_0.yyyyyyyy"
}

当然V1_0_0总会改变并且.yyyyyyyy会改变，但xxxxxxx将是相同的

这是我越接近：（？＆lt; = xxxxxxx）。*或（？＆lt; = xxxxxxx）。*

但这就是我得到的：

public void doSomething() {
    return "xxxxxxxV2_0_0;
}

xxxxxxx或yyyyyyyy可以是java类名中允许的任何字符

试试这样：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="navcontainer">
    <ul>
    <li>
    <label class=" container-check">Australia
    	<input class="filter-check country" type="checkbox" name="country" value="Australia">
    </label>
    </li>
    
    <li>
    <label class=" container-check">United Kingdom
    	<input class="filter-check country" type="checkbox" name="country" value="United Kingdom">
    </label>
    </li>
    
    <li>
    <label class=" container-check">USA
    	<input class="filter-check country" type="checkbox" name="country" value="USA">
    </label>
    </li>
    
    <li>
    <label class=" container-check">New Zealand
    	<input class="filter-check country" type="checkbox" name="country" value="New Zealand">
    </label>
    </li>
    </ul>
    </div>
    <div id="navcontainer1">
    <ul>
    <li>
    <label class=" container-check">Vineyard / Viticulture
    	<input class="filter-check category" type="checkbox" name="country" value="Vineyard / Viticulture">
    </label>
    </li><li>
    <label class=" container-check">Winemaking / Lab / Production
    	<input class="filter-check category" type="checkbox" name="country" value="Winemaking / Lab / Production">
    </label>
    </li><li>
    <label class=" container-check">Harvest / Vintage 
    	<input class="filter-check category" type="checkbox" name="country" value="Harvest / Vintage">
    </label>
    </li>
    <li>
    <label class=" container-check">Cellar Door
    	<input class="filter-check category" type="checkbox" name="country" value="Cellar Door">
    </label>
    </li>
    <li>
    <label class=" container-check">General Management
    	<input class="filter-check category" type="checkbox" name="country" value="General Management">
    </label>
    </li>
    <li>
    <label class=" container-check">Sales / Marketing / Retail / Distributor
    	<input class="filter-check category" type="checkbox" name="country" value="Sales / Marketing / Retail / Distributor">
    </label>
    </li>
    </ul>
    </div>

我使用(?:xxxxxxx)V[0-9]+_[0-9]+_[0-9]+(?:\.[a-z]+)?使yyyyyy部分可选。也许你需要一个不同于?的角色类，可能是a-z或[a-zA-Z]。
