问题

// 我需要在日志优化过程中在高级环境中移除不需要的日志，所以得到了移除字符串中的json或XML负载的要求。

String jsonString= "这是json字符串：{\"name\":\"xyz\",\"address\":\"pqr\"}";

String xmlString= "这是xml字符串，无法转换为XML内容的代码格式：\n\n<customer>John Smith</customer>";

// 尝试使用Jackson库处理json似乎有效，但我需要集成在这样的条件检查下，比如XML或json然后可以移除负载并设置为空值。期待您的帮助。

int i= str.indexOf("{");

JsonNode jsonNode = new ObjectMapper().readTree(str.substring(i));

ObjectNode object = (ObjectNode)jsonNode;

object.removeAll();

String jsonString= "This is jsonstring:{\"name\":\"xyz",\"address\":\"pqr\"}";

String xmlString= "This is xmlString not able to convert in code format of XML content:

<customer>John Smith</customer>";

int i= str.indexOf("{");

JsonNode jsonNode = new ObjectMapper().readTree(str.substring(i));

ObjectNode object = (ObjectNode)jsonNode;

object.removeAll();

根据您的两个示例，它应该如下所示：

```php
static String cleanUpLogItem(String logItem) {
    return logItem.substring(0, logItem.indexOf("：")).trim();
}

测试：

public class FooBarTest {

    @ParameterizedTest
    @MethodSource("dataProvider")
    void test_cleanUpLogItem(String logItem, String expected) {
        assertEquals(expected, cleanUpLogItem(logItem));
    }

    private static Stream<Arguments> dataProvider() {
        return Stream.of(
                Arguments.of(
                        "This is jsonstring:{\"name\":\"xyz\",\"address\":\"pqr\"}",
                        "This is jsonstring"
                ),
                Arguments.of(
                        "This is xmlString not able to convert in code format of XML content: <customer>John Smith</customer>",
                        "This is xmlString not able to convert in code format of XML content"
                )
        );
    }
}

Based on your two examples, it should look like this:

```php
static String cleanUpLogItem(String logItem) {
    return logItem.substring(0, logItem.indexOf(&quot;:&quot;)).trim();
}

Test:

public class FooBarTest {

    @ParameterizedTest
    @MethodSource("dataProvider")
    void test_cleanUpLogItem(String logItem, String expected) {
        assertEquals(expected, cleanUpLogItem(logItem));
    }

    private static Stream<Arguments> dataProvider() {
        return Stream.of(
                Arguments.of(
                        "This is jsonstring:{\"name\":\"xyz\",\"address\":\"pqr\"}",
                        "This is jsonstring"
                ),
                Arguments.of(
                        "This is xmlString not able to convert in code format of XML content: <customer>John Smith</customer>",
                        "This is xmlString not able to convert in code format of XML content"
                )
    }
}
