Comment analyser un fichier html pour suivre une donnée spécifique?

Question

Mon site Web cible est: http://www.imkb.gov.tr/Home.aspx

S'il vous plaît se concentrer sur ce que la page: "XU100 64.882,72 -1,36%" est sur le dessus ..

La cible exacte est 64.882,72 cette valeur ! ...

Quel est le meilleur moyen d'obtenir cette valeur?

Ma plate-forme: asp.net, C#

Answer 1

Eh bien, si vous regardez la source de la page, vous verrez que la ligne ressemble à ceci:

<span id="ctl00_cphTicker_ctl00_lblUlusal100">XU100 64.882,72&nbsp;&nbsp;</span> 

ne devrait pas être difficile à trouver la constante ctl00_cphTicker_ctl00_lblUlusal100 et ce qui vient après. En regardant un peu plus à la page, il est clair qu'il est mis à jour par AJAX (un contrôle Telerik). Si vous téléchargez le fiddler 2 et jetez un oeil je serais prêt à parier que ce ne serait pas difficile de comprendre leur API et de l'obtenir directement à la source. Le lire d'une page me semble un peu rond.
