UI.Vision宏添加条件分支后出现Unexpected Token错误求助

我有一个可正常运行的UI.Vision宏，功能是循环删除第2行直至该行不存在。尝试添加「当第2行不存在时执行Part2操作」的逻辑后，出现Unexpected Token错误。以下是可正常运行的Part1代码及待整合的Part2代码：

Part 1（可正常运行：循环删除第2行） #

[
    {
        "Command": "label",
        "Target": "loopStart",
        "Value": "",
        "Description": ""
    },
    {
        "Command": "store",
        "Target": "document.evaluate(\"//*[@id='cp2_lineItemGrid_gridView_lnkDelete_1']/div\", document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue != null",
        "Value": "elementExists",
        "Description": ""
    },
    {
        "Command": "gotoIf",
        "Target": "${elementExists} == true",
        "Value": "",
        "Description": ""
    },
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"cp2_lineItemGrid_gridView_lnkDelete_1\"]/div",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"cp2_lineItemGrid_gridView_lnkDelete_1\"]/div",
            "xpath=//tr[3]/td[18]/a/div",
            "css=#cp2_lineItemGrid_gridView_lnkDelete_1 > div"
        ],
        "Description": ""
    },
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"cp2_ucRemoveConfirmation_btnYes\"]/span",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"cp2_ucRemoveConfirmation_btnYes\"]/span",
            "xpath=//div[21]/div/div[2]/div/button/span",
            "css=#cp2_ucRemoveConfirmation_btnYes > span"
        ],
        "Description": ""
    },
    {
        "Command": "pause",
        "Target": "2500",
        "Value": "",
        "Description": ""
    },
    {
        "Command": "gotoLabel",
        "Target": "loopStart",
        "Value": "",
        "Description": ""
    }
]

Part 2（待整合：第2行不存在时执行） #

[
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"btnNext\"]/span",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"btnNext\"]/span",
            "xpath=//button[5]/span",
            "css=#btnNext > span"
        ],
        "Description": ""
    },
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"cp2_ucConfirmControl_btnContinue\"]/span",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"cp2_ucConfirmControl_btnContinue\"]/span",
            "xpath=//div[16]/div/div[2]/div[2]/button/span",
            "css=#cp2_ucConfirmControl_btnContinue > span"
        ],
        "Description": ""
    }
]

修正后的完整宏代码（解决Unexpected Token错误） #

报错原因是整合时JSON格式不合法（如括号、逗号不匹配），同时需要调整gotoIf的逻辑，让元素不存在时跳转到Part2执行：

[
    {
        "Command": "label",
        "Target": "loopStart",
        "Value": "",
        "Description": ""
    },
    {
        "Command": "store",
        "Target": "document.evaluate(\"//*[@id='cp2_lineItemGrid_gridView_lnkDelete_1']/div\", document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue != null",
        "Value": "elementExists",
        "Description": ""
    },
    // 元素不存在时，跳转到执行Part2的标签
    {
        "Command": "gotoIf",
        "Target": "${elementExists} == false",
        "Value": "executePart2",
        "Description": ""
    },
    // 元素存在时，执行删除操作
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"cp2_lineItemGrid_gridView_lnkDelete_1\"]/div",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"cp2_lineItemGrid_gridView_lnkDelete_1\"]/div",
            "xpath=//tr[3]/td[18]/a/div",
            "css=#cp2_lineItemGrid_gridView_lnkDelete_1 > div"
        ],
        "Description": ""
    },
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"cp2_ucRemoveConfirmation_btnYes\"]/span",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"cp2_ucRemoveConfirmation_btnYes\"]/span",
            "xpath=//div[21]/div/div[2]/div/button/span",
            "css=#cp2_ucRemoveConfirmation_btnYes > span"
        ],
        "Description": ""
    },
    {
        "Command": "pause",
        "Target": "2500",
        "Value": "",
        "Description": ""
    },
    {
        "Command": "gotoLabel",
        "Target": "loopStart",
        "Value": "",
        "Description": ""
    },
    // Part2操作的标签
    {
        "Command": "label",
        "Target": "executePart2",
        "Value": "",
        "Description": ""
    },
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"btnNext\"]/span",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"btnNext\"]/span",
            "xpath=//button[5]/span",
            "css=#btnNext > span"
        ],
        "Description": ""
    },
    {
        "Command": "click",
        "Target": "xpath=//*[@id=\"cp2_ucConfirmControl_btnContinue\"]/span",
        "Value": "",
        "Targets": [
            "xpath=//*[@id=\"cp2_ucConfirmControl_btnContinue\"]/span",
            "xpath=//div[16]/div/div[2]/div[2]/button/span",
            "css=#cp2_ucConfirmControl_btnContinue > span"
        ],
        "Description": ""
    }
]

逻辑说明 #

1. 每次进入loopStart标签，先检查第2行的删除按钮是否存在
2. 如果不存在，直接跳转到executePart2标签执行后续操作
3. 如果存在，执行删除、确认、暂停操作后，回到loopStart继续检查
4. Part2操作执行完毕后，宏自动结束，不会再循环
