Framelar



Misol:













Targetlar
target=”{frame nomi}|_self | _parent | _top | _blank”
{frame nomi} – ko’rsatilgan framega ochish;
_self – framening o’ziga ochish;
_parent – joriy oynaga faqat ssilka berilgan sahifani ochish;
_top – yuqori framega ochish;
_blank – yangi oynaga ochish;

Iframe

XML da ayrim teglar

I need a regex to find all '<' or '>' which is not xml-tags.

Misol:

WZ<>S

Topish kerak

<><<>

Misol:

WZ<>S

Topish kerak

<<>

So, any hits where '<' or '>' is not in a tag (yes we alos have al self-closing tags which should be taken into consideration :)

Edit #2: What I want to do in the end is to replace all matches with the html-encoded values.

# 3 tahrirlash:

So what I want to do is from a text containing HTML with some additional tags (very few known tags) get all '<' and '>' which is not included in the tags.

Misol (ularni topmoqchi bo'lgan jasur narsalar, ularni kodlangan qiymatlari bilan almashtira olaman):

Link with < characters

Text with character >

Text < again >

Result should be:

Link with < characters

Text with character >

Text < again >

Any idea on how to solve this problem?

Afsuski, men buni muntazam ravishda ifoda etishim mumkin. Lekin XMl/HTML regex parametrlarini tahlil qiluvchi shaxs sifatida ham, men regex echimini ishlab chiquvchi standartlarini o'qib berishni buzishim uchun buzishim kerakligini aytmoq kerak ... va faqat Regex bilan xushbo'y lazzat bilan ishlaydi. Sizga kerak bo'lgan narsa xml tegini topuvchi hisoblanadi, yoki bu 

o'z-o'zidan yopilishi kerak bo'lgan etiketni talab qilishi yoki u erda bir nechta to'g'ri ichki kirish yopiqligi tengdoshi bo'lishi kerak. InnerTextni ko'rish qobiliyatiga ega HTMLAgilityPack shaxsiy echim bo'lishi mumkin deb o'ylayman.

@ Karl-OttoKjellkvist: agar yaxshi tushunsam, "tag" nomi muhim emas. Bunday holatda, nima uchun atrofidagi ni birinchi namunangizda o'chirib tashlamoqchisiz, ya'ni o'zingiz yopadigan va siz aniqlagan (ikkinchi misolga qarang) yorlig'i nima?

Iltimos, bu masalada yordam beradigan bir ayrıştırıcı haqida ma'lumot bering. Men HTMLAgilityPack ga qaradim, ammo buni men ko'rmayapman.

Bu regex bilan amalga oshirilishi mumkin; Biroq, siz taklif qilayotganingiz kabi oddiy emas. Ushbu ishni bajarish uchun tegishli teglarni topib, ularni ishlov berishingiz kerak bo'ladi. Tez va engil xml/HTML parserini yozishda biroz oldin shu ishni qildim. Kod quyidagi manzilda mavjud:

http://csharptest.net/browse/src/Library/Html/XmlLightParser.cs http://csharptest.net/browse/src/Library/Html/XmlLightInterfaces.cs

Tahrirlash vositasidan foydalanish uchun IXmlLightReader ni aniqlangan ikkita manba faylidan keyin amalga oshirasiz. Quyidagi misol sizning istagan natijalaringizni ishlab chiqaradi va CDATA bo'limlari, ishlov berish bo'yicha yo'riqnomalar, DTD va boshqalar kabi bir qator boshqa qobiliyatlarni ko'rib chiqadi.

class RegexForBadXml

{

const string Input = "\r\n

\r\n\tLink with < characters\r\n\tText with character > &and other &#BAD; stuff\r\n\tText < again >\r\n\t

]]>

\r\n

";

private static void Main()

{

var output = new StringWriter();

XmlLightParser.Parse(Input, XmlLightParser.AttributeFormat.Html, new OutputFormatter(output));

Console.WriteLine(output.ToString());

}

private class OutputFormatter : IXmlLightReader

{

private readonly TextWriter _output;

public OutputFormatter(TextWriter output)

{

_output = output;

}

void IXmlLightReader.StartDocument() { }

void IXmlLightReader.EndDocument() { }

public void StartTag(XmlTagInfo tag)

{

_output.Write(tag.UnparsedTag);

}

public void EndTag(XmlTagInfo tag)

{

_output.Write(tag.UnparsedTag);

}

public void AddText(string content)

{

_output.Write(HttpUtility.HtmlEncode(HttpUtility.HtmlDecode(content)));

}

public void AddComment(string comment)

{

_output.Write(comment);

}

public void AddCData(string cdata)

{

_output.Write(cdata);

}

public void AddControl(string cdata)

{

_output.Write(cdata);

}

public void AddInstruction(string instruction)

{

_output.Write(instruction);

}

}

}

The preceeding program outputs the following results:

Link with < characters

Text with character > &and other &BAD; stuff

Text < again >



]]>

Note: I added the xml declaration, CDATA, and '&' text for testing only.

Bu savol dan bir usuldan foydalaning va kirishning html teglarini olib tashlang

keyin

string output = new string(input.ToCharArray().Where(c=> c=='<'||c=='>').ToArray());

Judging from your example, it seems you are not searching xml files as the subject suggests, but rather XML-like files - perhaps files that would be xml if they did not contain the "<" and ">" characters that you are looking for.

Ammo vazifani etarlicha aniq ko'rsatmadingiz. Masalan, qanday bo'lishi kerak

xxxx

yoki

Ikkinchidan, odatdagi iboralar bilan erishish uchun juda qiyin (ehtimol imkonsiz). Grammatikani yoki siz qabul qilmoqchi bo'lgan kirish tilini (XML kengaytmasini) aniqlab olishingiz va uni recursiv ajralish texnikasi yordamida tahlil qilishingiz kerak.

Menda mavjud bo'lgan ba'zi bir qo'shimcha teglar bilan birga HTML-sahifa mavjud. Keyin foydalanuvchi "<" va ">" ni qo'shishlari kerak. Shunday qilib, yuqoridagi misollar beparvo emas, 1-misol haqiqiy emas va misol uchun, 2 hisobga olinmaydi.

Men sizning savolingizga juda ko'p tushunchani tushunmadim, lekin men sizning HTML namunangizni olgan va HTML natijasini kutilgan HTML natijalari bilan qaytarib beradigan kodni yozdim.

MatchCollection matches = Regex.Matches(YourHTML, @"(?<=<.*?>).+(?=<.*?>)");

foreach (Match match in matches)

{

YourHTML = YourHTML.Replace(match.Value, HttpUtility.HtmlEncode(match.Value));

}

Given the new formulation of your problem in edit #3, I think you could solve it with a regular expression that matches "<" followed by a negative lookahead

<(?!(/?(a|b|div|p|....|!--|!\[CDATA\[))

which matches < if not followed by one of the known tag-names, and then replace this "<" with "<"

Sizning cheklangan holatlarda sizda ishlaydigan algoritmli strategiya mavjud bo'lib ko'rinadi, bu quyidagicha tavsiflanadi:

1. 
   Search left to right for an open tag, i.e. .
   
2. 
   If found, search the remaining string for the matching close tag,
   
3. 
   Recursively repeat steps one and two for the string between the open and close tags just found for as long as you can find matching pairs
   
4. 
   For sequences of the string where no open/close tag pair is found, replace all occurrences of < and > with the escapes.
