Regexp with multiple lines
Ältere Kommentare anzeigen
Hello, I would like to use urlread and regexp to extract a specific number from the url. Part oftThe content of the url is:
<td class="text-right">1</td>
<td data-sort="Ethereum"><img src="https://s2.coinmarketcap.com/static/img/coins/16x16/1027.png" class="logo" alt="Ethereum"><a href="/currencies/ethereum/" class="market-name">Ethereum</a></td>
<td data-sort="ETH/USD"><a href="https://www.kraken.com" target="_blank">ETH/USD</a></td>
<td class="text-right" data-sort="41450600.0">
<span class="volume" data-usd="41450600.0" data-btc="4441.21" data-native="54539.6">
$41,450,600
</span>
</td>
<td class="text-right" data-sort="760.01">
<span class="price" data-usd="760.01" data-btc="0.0814309" data-native="760.01">
$760.01
</span>
</td>
<td class="text-right" data-sort="20.679496448"><span data-format-percentage data-format-value="20.679496448">20.68</span>%</td>
<td class="text-right ">Recently</td>
</tr>
<tr>
<td class="text-right">2</td>
<td data-sort="Bitcoin"><img src="https://s2.coinmarketcap.com/static/img/coins/16x16/1.png" class="logo" alt="Bitcoin"><a href="/currencies/bitcoin/" class="market-name">Bitcoin</a></td>
<td data-sort="BTC/EUR"><a href="https://www.kraken.com" target="_blank">BTC/EUR</a></td>
<td class="text-right" data-sort="36350300.0">
<span class="volume" data-usd="36350300.0" data-btc="3894.74" data-native="3905.16">
$36,350,300
</span>
</td>
<td class="text-right" data-sort="9308.28">
<span class="price" data-usd="9308.28" data-btc="0.997331" data-native="7839.6">
$9308.28
</span>
I would like to extract this content, that begins with the word Ethereum and finishes with the number 760.01:
Ethereum</a></td>
<td data-sort="ETH/USD"><a href="https://www.kraken.com" target="_blank">ETH/USD</a></td>
<td class="text-right" data-sort="41450600.0">
<span class="volume" data-usd="41450600.0" data-btc="4441.21" data-native="54539.6">
$41,450,600
</span>
</td>
<td class="text-right" data-sort="760.01">
<span class="price" data-usd="760.01" data-btc="0.0814309" data-native="760.01">
$760.01
I'm trying to use this code, but I don't know what expression to use:
urlKraken='https://coinmarketcap.com/exchanges/kraken/';
strC=urlread(urlKraken);
expression='';
[startIndex,endIndex] = regexp(strC,expression);

"... finishes with the number 760.01" - I see 4 occurrences of "760.01" in the shown snippet. Which one is the wanted one? "Etherum" can be found multiple times also.
Are coinmarketcap or kraken.com commercial services?

Then my answer below should do the trick. Added bonus is that it first finds the value as well. If that solves your question, please consider marking it as accepted answer, if not, please describe your remaining issues with that code.
