Jsoup 库 "Did not find balanced marker" 错误

Question

使用 jsoup 库，我试图获取 <a> 元素的 href，每次都包含指定的文本。

示例：

import org.jsoup.Jsoup
import org.jsoup.nodes.Document
import org.jsoup.select.Elements

public class GlobVars {
    public static Document currentPageSource
    public static String currentTitle
}

def get_url() {
    String url = "https://www.website.com/"
    GlobVars.currentPageSource = Jsoup.connect(url).get()

    Elements wElements = GlobVars.currentPageSource.select('a[class="class-name"]:contains('+GlobVars.currentTitle+')')
    if(wElements) {
        /*
         * Do stuff...
         * 
         * */
    }
}

问题是 GlobVars.currentTitle 包含单引号字符！！！例如，如果 GlobVars.currentTitle 是 I am here 它“工作”正常。但是如果 GlobVars.currentTitle 是 I'm here 我得到这个错误： Did not find balanced marker at 'I'.

我尝试将 GlobVars.currentTitle 变量与 double-quoted、triple-single-quoted 或 triple-double-quoted 一起使用，但我得到了同样的错误。

我还阅读了 https://github.com/jhy/jsoup/issues/1105 but the "trick" 转义引号不能用于我的情况。

知道我将如何解决这个问题吗？

// @Grab(group='org.jsoup', module='jsoup', version='1.14.3')

import org.jsoup.Jsoup
import org.jsoup.nodes.Document
import org.jsoup.select.Elements

def html = """
<html>
<body>
<a class="c1" href="#1">i'm the one</a>
<a class="c1" href="#2">i am the one</a>
</body>
</html>
"""

def desiredText = "i'm the one"
// escape special chars. maybe you need more special chars to escape...
desiredText = desiredText.replaceAll(/(['"\\/\|(\)\[\]])/, '\\') 

Document currentPageSource = Jsoup.parse(html)
Elements wElements = currentPageSource.select('a[class="c1"]:contains('+ desiredText +')')

或

def desiredText = "i'm the one"
Elements wElements = currentPageSource.select('a[class="c1"]').findAll{it.html().contains(desiredText)}
