救命！提升正则表达式异常 [英] Help! Boost regular expression exception
问题描述
正则表达式：（？< = \D | ^）（1 [358] \d {9}）（？= \D | $）
当我使用boost regex时
：
char pat [] = { （？< = \\D | ^）（1 [358] \\\ \\d {9}）（= \\D | $）}？;
boost :: regex reg（pat）;
这里抛出异常！
如果我使用POSIX，没有异常，但无法匹配，例如：
boost :: regex reg（pat，regbase :: basic_syntax_group）;
std :: string str（+ 86 18601234567 tel。）;
bool matched = regex_match（str，reg）; //假!!!
谁能告诉我这是怎么回事？请发送电子邮件至jianggx@hotmail.com，谢谢！
我尝试过：
当我使用C＃时，没关系。
例如：
< span class =code-keyword> string pat = @ （？< = \ D | ^）（1 [358] \d {9}）（= \D | $）？;
string myinfo = 自定义名称：name1 ;电话：+86 18601234567;地址：北京。;
Regex rg = new 正则表达式（模式）;
MatchCollection mc = rg.Matches（myinfo）;
）
当我使用boost regex时：
char pat [] = { （？< = \\D | ^）（1 [358] \ \d {9}）（= \\D |
）}？;
boost :: regex reg（pat）;

Regular Expression: (?<=\D|^)(1[358]\d{9})(?=\D|$)
when I use boost regex:
char pat[] = {"(?<=\\D|^)(1[358]\\d{9})(?=\\D|$)"};
boost::regex reg(pat);
here throw an exception!
If I use POSIX, no exception, but can't match, for example:
boost::regex reg(pat, regbase::basic_syntax_group);
std::string str("+86 18601234567 tel.");
bool matched = regex_match(str, reg); // false!!!
who can tell me what's the matter? Pls send email to jianggx@hotmail.com, thanks!
What I have tried:
when I use C#, it's ok.
for example:
string pat = @"(?<=\D|^)(1[358]\d{9})(?=\D|$)";
string myinfo= "custom name: name1;tel:+86 18601234567;addr:beijing.";
Regex rg = new Regex(pattern);
MatchCollection mc = rg.Matches(myinfo);)
when I use boost regex:
char pat[] = {"(?<=\\D|^)(1[358]\\d{9})(?=\\D|
)"}; boost::regex reg(pat);
here throw an exception!
If I use POSIX, no exception, but can't match, for example:
boost::regex reg(pat, regbase::basic_syntax_group);
std::string str("+86 18601234567 tel.");
