我在这里做错了吗？
答案 0 :(得分：2)
您的AtlasEntry项目无效XML。你的属性之间不能有逗号;这导致了一个解析错误，这就是你得到空值的原因。
例如，
<AtlasEntry id="card16" x="1470.0" y="694.0" w="180" h="250", a="3", d="3", name="'Posion Tongue' McGillicutty", team="horde" />
应该是
<AtlasEntry id="card16" x="1470.0" y="694.0" w="180" h="250" a="3" d="3" name="'Posion Tongue' McGillicutty" team="horde" />
修复所有AtlasEntry项目，你应该好好去。
答案 1 :(得分：2)
<AtlasEntry id="card1" x="0" y="950.0" w="180" h="250", a="2", d="3", name="Teresa Voldheart", team="horde" />
这不是有效的XML，属性之间的逗号不应该存在，请查看当达到第一个逗号时解析器的值如何停止。我很惊讶解析器不会将此报告为错误。
