Semgrep：简单的 HTML 匹配

Question

我知道 HTML 在 Semgrep 中是实验性的，但我希望它能在非常简单的匹配上工作（Bash 也是实验性的，并且 它已经足够好了）.

如何匹配具有相同 ID 的任意两个元素？

<!-- this should match since both have same IDs -->
<div id="a"></div>
<div id="a"></div>

<!-- this should match since both have same IDs, even though spacing is different (valid HTML) -->
<div id="b"></div>
<div id = "b"></div>

<!-- this should match since both have same IDs, even though different tags -->
<div id="c"></div>
<span id="c"></div>

<!-- self-closing tags should match too -->
<link id="d" rel="stylesheet" href="styles.css"> 
<span id="d"></span>

尝试

在操场上试试

rules:
  - id: dupe_id
    message: duplicate IDs not allowed
    languages:
      - html
    severity: ERROR
    patterns:
      - pattern-either:
        # Both not self-closing
        - pattern: <$TAGA id="$X"></$TAGA><$TAGB id="$X"></$TAGB>
        # First self-closing
        - pattern: <$TAGA id="$X" /><$TAGB id="$X"></$TAGB>
        # Second self-closing
        - pattern: <$TAGB id="$X"></$TAGB><$TAGA id="$X" />
        # Both self-closing
        - pattern: <$TAGB id="$X" /><$TAGA id="$X" />

错误

Attemp 只给出了一场比赛，但预期是 4.
