Question

我想从html响应下面得到2269。我用

<td>XYZ Market Services \(Sydney\)</td>(?s).*name="addCompany" value="(.+?)"

使用$ 1 $模板和匹配编号1的正则表达式，但它返回2271.有人请帮我创建一个正则表达式以获得值2269。

        <tr>
            <td>XYZ Market Services (Sydney)</td>
            <td class="center">
                <form action="/FormBuilder/pages/Folders/add.aspx?group=1424sfksdfsdgdsf243-3Q-w&ajax=true" method="post">
                    <input name="addCompany" value="2269" type="hidden" /><input class="XYZLookAlike" type="button" onclick="fnload(this)" value="Add" />
                </form>
            </td>
        </tr>

        <tr>
            <td>XYZ Market Services (Melbourne)</td>
            <td class="center">
                <form action="/FormBuilder/pages/Folders/add.aspx?group=1424sfksdfsdgdsf243-3Q-w&ajax=true" method="post">
                    <input name="addCompany" value="2271" type="hidden" /><input class="XYZLookAlike" type="button" onclick="fnload(this)" value="Add" />
                </form>
            </td>
        </tr>

谢谢...

Don't use regular expressions to parse HTML，有更好的选择。

例如，您可以使用允许对响应执行任意XPath Extractor的XPath queries，以下是为public class UIIssueVM : ViewModels.Issue.IssueVM, INotifyPropertyChanged { public UIIssueVM() { Id = 0; Title = ""; Description = ""; Created = DateTime.Now; Edited = DateTime.Now; } public UIIssueVM(bool bIsNew) { IsNew = true; Id = 0; Title = ""; Description = ""; CreatedBy = App.Client.GetCurrentUsername(); Created = DateTime.Now; Edited = DateTime.Now; } public UIIssueVM(ViewModels.Issue.IssueVM issue) { LocationId = issue.LocationId; Id = issue.Id; Title = issue.Title; Description = issue.Description; Longitude = issue.Longitude; Latitude = issue.Latitude; Status = issue.Status; Severity = issue.Severity; Created = issue.Created; Edited = issue.Edited; CreatedBy = issue.CreatedBy; } public ViewModels.Issue.NewIssueVM CreateNewIssueVM() { ViewModels.Issue.NewIssueVM issue = new ViewModels.Issue.NewIssueVM(); issue.LocationId = LocationId; issue.Title = Title; issue.Description = Description; issue.Longitude = Longitude; issue.Latitude = Latitude; issue.Status = Status; issue.Severity = Severity; return issue; } public ViewModels.Issue.IssueVM CreateUpdatedIssueVM() { ViewModels.Issue.IssueVM issue = new ViewModels.Issue.IssueVM(); issue.Id = Id; issue.LocationId = LocationId; issue.Title = Title; issue.Description = Description; issue.Longitude = Longitude; issue.Latitude = Latitude; issue.Status = Status; issue.Severity = Severity; issue.CreatedBy = issue.CreatedBy; return issue; } private void NotifyPropertyChanged([CallerMemberName] String propertyName = "") { // System.Diagnostics.Debug.WriteLine("Update!"); //ok if (PropertyChanged != null) { //PropertyChanged is always null and shouldn't. PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } public bool Changed { get { return this.IssueChanged; } set { IssueChanged = value; NotifyPropertyChanged(); } } public string TitleEx { get { return this.Title; } set { if (this.Title != value) { this.Title = value; NotifyPropertyChanged(); Changed = true; } } } public string DescriptionEx { get { return this.Description; } set { if (this.Description != value) { this.Description = value; NotifyPropertyChanged(); Changed = true; } } }输入提取value属性的示例，其中列文本为{ {1}}

要解析HTML，在可维护性/易用性/性能方面，最好的提取器是CSS/JQuery extractor：
