正则表达式html获取具有特定属性的属性

Question

我想从具有其他特定属性的html标记获取属性值。

int main(int argc, char **argv) {
    omrthread_t attachedThread = NULL;
    J9PortLibraryVersion portver;
    J9PortLibrary portlib;
    intptr_t rc;
    intptr_t fd;

    rc = omrthread_init_library();
    if (rc != 0) {
        printf("omrthread_init_library failed with: %lld\n", rc);
        return 1;
    }

    rc = omrthread_attach_ex(&attachedThread, J9THREAD_ATTR_DEFAULT);
    if (rc != 0) {
        printf("omrthread_attach_ex failed with: %lld\n", rc);
        return 1;
    }

    J9PORT_SET_VERSION(&portver, J9PORT_CAPABILITY_MASK);
    rc = j9port_init_library(&portlib, &portver, sizeof(portlib));
    if (rc != 0) {
        printf("j9port_init_library failed with: %lld\n", rc);
        return 1;
    }

Answer 1

你想要这样的东西：

var attrRegExp = /<(?=[^>]+attr1)[^>]+attr2=["']([^"']+)/ig;
var match = attrRegExp.exec(text);
while (match != null) {
    // capturing group 1: match[1]
    match = attrRegExp.exec(text);
}

这将遍历所有HTML，并且相关属性将匹配[1]。例如，您可以将所有匹配推送到数组。
