I'm beginner and i want to ask how get or search after embed "MAT3z3xtcd4" and before "
from this strings

this iframe in my website under Videos Category
There's a thousand ways to do this, but many of them are just simple string splitting, substringing, etc. Check the documentation for String.
Here's a simple, verbose example that demonstrate several of those techniques:
void main() {
String s = '<iframe src="https://www.youtube.com/embed/MAT3z3xtcd4" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe>';
List<String> tags = s.replaceAll('<', ' ').replaceAll('>', ' ').split(' ');
print(tags);
String srcTag = tags.where((s) => s.startsWith('src=')).first;
print (srcTag);
String url = srcTag.substring(5, srcTag.length - 1);
print(url);
String suffix = url.split('/').last;
print(suffix);
}

I spent so much time on a very simple thing and had to post here on StackOverflow
I want to get all inner text except the script/style tags
$doc = new DOMDocument;
$doc->preserveWhiteSpace = false;
$html = <<<EOD
<div>
<script>var main=0</script>
<div>
<p>my</p>
<script>var inner=0</script>
</div>
<p>text</p>
only
</div>
EOD;
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
echo $entries = $xpath->query('//*[not(self::script)]')->item(0)->nodeValue;
gives me
var main=0 my var inner=0 text only
and also tried
$entries = $xpath->query('//*[not(self::script)]');
foreach ($entries as $entry) {
if ($entry->tagName == 'style' || $entry->tagName == 'script') {
continue;
}
echo preg_replace('/\s\s+/', ' ', $entry->nodeValue);
}
gives me
var main=0 my var inner=0 text only var main=0 my var inner=0 text only var main=0 my var inner=0 text only my var inner=0mytext
I tried several xpaths but it doesn't work
my desired output is my text only
I am a Scrapy developer and I do that easily in Scrapy, but having a bad time with PHP today
Unfortunately, PHP doesn't support xpath 2.0 (and, IIRC, neither does Scrapy), so the name() method which would have made it easy, isn't available...
The closest thing I can think of is the following, which should get you close enough (note that, because there is no <style> tag in your $html, I only focused on <script>):
$entries = $xpath->query('//*[not(./text()/parent::script)]/text()');
foreach ($entries as $entry) {
echo trim($entry->textContent) . " ";
}
Output:
my text only
I have an TYPO3 extension which shows a list of records. As it are more than 40 pages I would like to provide an additional alphabetic index which enables visitors to jump directly to the beginning of a character.
In general all is working - except the link to the n-th page.
I have the fluid variables cur containing current character (e.g. M) and the necessary page number in pageNumber (e.g. 23).
How can I get the correct url which should look like:
https://mydomain.tld/path/to/list?tx_myextension_myextension[#widget_0][currentPage]=23&cHash=a6193a7eab129df4789343911221584b#jumplabel_M
either
<a class="page-link" href="{f:uri.page(additionalParams:{tx_myextension_myextension{#widget_0:{currentPage:pageNumber}}})}#jmplabel_{cur}">{cur}</a>
nor
<a class="page-link" href="{f:uri.page(additionalParams:{tx_myextension_myextension[#widget_0][currentPage]:pageNumber})}#jmplabel_{cur}">{cur}</a>
call the f:uri.page VH. The result is an unreplaced string in the href-parameter.
<a class="page-link" href="{f:uri.page()}?tx_phonebook_phonebook[#widget_0][currentPage]={pageNumber}#jmplabel_{cur}">{cur}</a>
looks ok, but misses the cHash and therefore results in 404 page not found.
Check how Georg Ringer does it in his News extension. Actually that's a solution for your pagination.
PaginateAdditionalParamsViewHelper.php:
https://github.com/georgringer/news/blob/master/Classes/ViewHelpers/Widget/Ajax/PaginateAdditionalParamsViewHelper.php#L30
public function render()
{
$page = (int)$this->arguments['page'];
if ($page === 0) {
return [];
}
$params = [
'tx_news_pi1' => [
'#widget_0' => [
'currentPage' => $page
]
]
];
return $params;
}
And in some template:
https://github.com/georgringer/news/blob/master/Resources/Private/Templates/Styles/Twb/Templates/ViewHelpers/Widget/Paginate/IndexAjax.html#L56, especially additionalParams key.
<f:widget.link data="{container:recordId,link:'{t:uri.ajaxAction(contextRecord:\'tt_content:{recordId}\', pluginName: \'pi1\',additionalParams:\'{n:widget.ajax.paginateAdditionalParams(page:0)}\')}'}">
<f:translate key="paginate_previous" />
</f:widget.link>
Dears,
I have arabic sentence like this stentence
أكل الولد التفاحة
how can i split the sentence based on UNCONNECTED characters to be like this :
أ-
كل
ا-
لو-
لد
ا-
لتفا-
حة
I put - to explain what i mean.
I just need to split the text into array based on that
How can i do that using swift code for ios ?
Update:
I dont care for the spaces.
"أكل" for example is one word and doesn't contain spaces.I want to split based on UNCONNECTED characters.
So "أكل" consist from two objects : "أ" and "كل"
الولد : three objects "ا" and "لو" and "لد"
Use the below code:
let a = "أكل الولد التفاحة".split(separator: " ")
You can replace spaces with "-" using replacing occurences function.
let text = "أكل الولد التفاحة".replacingOccurrences(of: " ", with: "-", options: NSString.CompareOptions.literal, range: nil) ?? ""
I don't know how accepted answer helps to fix the issue.
Apple already provided Natural Language Framework to handle such a things which more trustworthy
When you work with natural language text, it’s often useful to tokenize the text into individual words. Using NLTokenizer to enumerate words, rather than simply splitting components by whitespace, ensures correct behavior in multiple scripts and languages. For example, neither Chinese nor Japanese uses spaces to delimit words.
Here is example
let text = """
All human beings are born free and equal in dignity and rights.
They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood.
"""
let tokenizer = NLTokenizer(unit: .word)
tokenizer.string = text
tokenizer.enumerateTokens(in: text.startIndex..<text.endIndex) { tokenRange, _ in
print(text[tokenRange])
return true
}
Here is link of Apple docs
Hope it is helpful

I have some tekst and in the middle of article I put {youtube}IPtv14q9ZDg{/youtube}. How to make code which is between {youtube} generated in youtube embed
I use PHP, but there might be other options.
I filter the text for the key-words. Then take the 11 digit code and wrap it in a link tag. Works best in a "for loop".
This is one I use to find url's in my text and make them live. But you can modify it to do what you want by changing the "preg_match" setting.
function make_clickable($string) {
$string = preg_replace("/[\n\r]/"," <br /> ",$string);
$arr = explode(' ', $string);
foreach($arr as $key => $value){
if(preg_match('#((^https?|http|ftp)://(\S*?\.\S*?))([\s)\[\]{},;"\':<]|\.\s|$)#i', $value)){
$arr[$key] = "<a class=\"custome\" href='". $value ."' target=\"_blank\" class='link'>$value</a> ";
}
}
$string = implode(' ', $arr);
return $string;
}
I have multiple pages generated using PDFKit. How can I add page numbers to the bottom?
PDFKit.configure do |config|
config.default_options = {
header_right: "Page [page] of [toPage]"
}
end
kit = PDFKit.new(body_html)
Read all detailed documentation here:
http://madalgo.au.dk/~jakobt/wkhtmltoxdoc/wkhtmltopdf-0.9.9-doc.html
PDFKit is just a wrap up for wkhtmltopdf application that is written in C.
you need to specify a footer like this:
kit = PDFKit.new(your_html_content_for_pdf, :footer_html => "#{path_to_a_footer_html_file}")
then in the footer file have this:
<html>
<head>
<script type="text/javascript">
function subst() {
var vars={};
var x=document.location.search.substring(1).split('&');
for(var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];
for(var i in x) {
var y = document.getElementsByClassName(x[i]);
for(var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
}
}
</script>
</head>
<body style="margin: 0;" onload="subst();">
Page <span class="page"></span> of <span class="topage"></span>
</body>
</html>
elements of classes 'frompage','topage','page','webpage','section','subsection','subsubsection' will get substituted with the appropriate data
I did page number with PDFKit, just by adding this:
%meta{:name => 'pdfkit-footer_right', :content => "[page]"}
in my haml file, in my RoR project.
For some weird reason, ( perhaps because I'm using slim ) - I have to use single quotes around the content, instead of double quotes - or else it attempts to escape the brackets and raw text "[page]" shows up, so try single quotes if you run into this issue with your pages.
