正则表达式匹配两个字符串之间多次出现的字符串

Question

我正在尝试匹配两个字符串之间多次出现的数字。

"ELE:和 ":{"isHidden":true}得到之间的数字。

我有(?<={"ELE:)(.*)(?=":{"isHidden":true})但这会选择整个组。

如何让它只匹配数字？

{"version":2,"(sectionConfig)":{"SECT:1236":{"children":{"ELE:1826":{"children":{"ELE:4217":{"(isHidden)":true},"ELE:22043":{"isHidden":true},"ELE:4253":{"isHidden":true},"ELE:1796":{"isHidden":true},"ELE:3907":{"isHidden":true}},"defaultSelectionId":"ELE:1781"},"ELE:1850":{"defaultSelectionId":"ELE:2657"},"ELE:1832":{"children":{"ELE:602":{"isHidden":true},"ELE:3864":{"isHidden":true},"ELE:650":{"isHidden":true}},"defaultSelectionId":"ELE:605"},"ELE:3711":{"isHidden":true}}},"SECT:2789":{"children":{"ELE:3923":{"isHidden":true},"ELE:3932":{"isHidden":true},"ELE:3920":{"isHidden":true},"ELE:3929":{"isHidden":true},"ELE:3938":{"isHidden":true},"ELE:3917":{"isHidden":true},"ELE:3926":{"isHidden":true},"ELE:3935":{"isHidden":true},"ELE:2834":{"isHidden":true},"ELE:2837":{"isHidden":true},"ELE:2960":{"isHidden":true},"ELE:2675":{"isHidden":true},"ELE:2933":{"isHidden":true},"ELE:2690":{"isHidden":true},"ELE:2717":{"isHidden":true},"ELE:3011":{"isHidden":true},"ELE:2681":{"isHidden":true},"ELE:2723":{"isHidden":true},"ELE:2693":{"isHidden":true},"ELE:2795":{"isHidden":true},"ELE:3014":{"isHidden":true},"ELE:2708":{"isHidden":true},"ELE:2975":{"isHidden":true},"ELE:2729":{"isHidden":true},"ELE:2996":{"isHidden":true},"ELE:2987":{"isHidden":true},"ELE:2672":{"isHidden":true},"ELE:2684":{"isHidden":true},"ELE:2669":{"isHidden":true}}},"SECT:2531":{"children":{"ELE:1862":{"children":{"ELE:26661":{"isHidden":true},"ELE:26682":{"isHidden":true},"ELE:26631":{"isHidden":true},"ELE:26601":{"isHidden":true}},"defaultSelectionId":"ELE:647"},"ELE:2690":{"isHidden":true},"ELE:2637":{"isHidden":true},"ELE:2485":{"isHidden":true},"ELE:1832":{"children":{"ELE:650":{"isHidden":true},"ELE:602":{"isHidden":true}},"defaultSelectionId":"ELE:605"},"ELE:2599":{"isHidden":true},"ELE:2521":{"isHidden":true},"ELE:1826":{"children":{"ELE:27478":{"isHidden":true},"ELE:27469":{"isHidden":true},"ELE:27460":{"isHidden":true},"ELE:27445":{"isHidden":true},"ELE:27436":{"isHidden":true},"ELE:27427":{"isHidden":true},"ELE:1796":{"isHidden":true},"ELE:4217":{"isHidden":true},"ELE:22043":{"isHidden":true},"ELE:27115":{"isHidden":true},"ELE:3907":{"isHidden":true}},"defaultSelectionId":"ELE:1781"}}}}}

Answer 1

你可以使用

(?<="ELE:)\d+(?=":{"isHidden":true})

参见 regex demo .

详细信息

• (?<="ELE:) - "ELE:必须立即出现在当前位置的左侧
• \d+ - 一位或多位数字
• (?=":{"isHidden":true}) - ":{"isHidden":true}必须立即出现在当前位置的右侧。
