Android Question RegEx Matcher with HTML Code

[hasexxl1988]

Hello,
i have follow problem:

i have HTML Code from a Website:

Example:

<span itemprop='name'>
                Ferrari TestCar
            </span>

i need the Name of the Car.

i have tryed with following Code:

If Job.JobName = "PageJob" Then
            Dim mAutoName As Matcher = Regex.Matcher("<span itemprop='name'>""([^""]+)""</span>", Job.GetString)
            Do While mAutoName.Find
                namelinks.Add(mAutoName.Group(1))
            Loop
            BuildItems
        End If

Result is only: []

Download and Job function works perfect with my ImageDownloader

Images URLs with this Code Working:

Dim m As Matcher = Regex.Matcher("src=\""https://mywebsite/mmo([^""]+)""", Job.GetString)

i have found de RegEx Pattern List: https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

Unfortunately, I do not know how to put together the value that the HTML code is removed

do a replace of linefeeds, tabs and double spacings (it makes it a lot easier) and then try

Regex.Matcher("<span itemprop='name'>(.*?)</span>", Job.GetString)

Not Working :/

i have try:

If Job.JobName = "PageJob" Then
            Dim xtemp As String
            xtemp = Job.GetString
            Log ("IndexOf: " & xtemp.IndexOf("<span itemprop='name'>"))
            Dim m As Matcher = Regex.Matcher("<span itemprop='name'>(.*?)</span>", Job.GetString)
            Do While m.Find
                Log (m.Group(1))
                    namelinks.Add(m.Group(1))
            Loop
            BuildItems
        End If

Log result with IndexOf: IndexOf: 112851

With IndexOf i can find the <span itemprop='name'> in the String. With Matcher not found.

You could test jsoup lib to get the contents searching for tag or Id in the html file (https://www.b4x.com/android/forum/threads/jsoup-html-parser.49152/#content)

Hi,
I tried the following on an on-line regex tool and it works, altough I don't think is an elegant solution; it simply works with data from post #1.

<span itemprop='name'>\s*(.*)\s*<\/span>

In Group 1 you read Ferrari TestCar.
Fundamentally it matches any number of whitespaces after "'name'>", followed by the group containing the car model, followed again by any number of whitespaces chars, finally followed by </span>

you didn't do it right. I told you to remove line breaks, tabs and extra spacing. this breaks regex lookups unless you add more lookup data.

You should use jSoup or jTidy to parse html.
