dom - PHP - Trying to display xml tag(tags with same name) nodevalue -


I am trying to display information from an XML file. I am using PHP and its DOMDocument class. I'm attaching the xml file and php code i have tried 

  & lt ;? XML version = "1.0" encoding = "utf-8"? & Gt; & Lt; Services & gt; & Lt; Services & gt; & Lt; Type & gt; Wash & lt; / Type & gt; & Lt; Title & gt; Wash1 & lt; / Title & gt; & Lt; Content & gt; Full External Hand Wash & lt; / Content & gt; & Lt; Content & gt; Chamois dry, pressure clean wheels, all doors jazz & lt; / Content & gt; & Lt; Content & gt; Plus Free Type Gloss & lt; / Content & gt; & Lt; Price & gt; Hatch / sedan: $ 15 & lt; / Pricing & gt; & Lt; Price & gt; Other: $ 20 & lt; / Pricing & gt; & Lt; / Services & gt; & Lt; Services & gt; & Lt; Type & gt; Wash & lt; / Type & gt; & Lt; Title & gt; Wash2 & lt; / Title & gt; & Lt; Content & gt; Wash1 & lt; / Content & gt; & Lt; Content & gt; Plus vacuum & lt; / Content & gt; & Lt; Content & gt; Glass Clear (IN / OUT) & lt; / Content & gt; & Lt; Content & gt; Plus free internal wipe & lt; / Content & gt; & Lt; Price & gt; Hatch / sedan: $ 30 & lt; / Pricing & gt; & Lt; Price & gt; Other: $ 38 & lt; / Pricing & gt; & Lt; / Services & gt; & Lt; / Services & gt;

php code ... 

  & lt ;? Php header ('content-type: text / html; charset = UTF8'); $ Xmlfile = new DOMDocument (); $ Xmlfile-> Load ('services.xml'); $ Services = $ xmlfile-> GetElementsByTagName ('service'); Foreign Currency ($ Service $ as Service) {$ titles = $ Service-> GetElementsByTagName ('title'); $ Title = $ title- & gt; Items (0) - & gt; Node vela; Echo "
 Title = / h1>"; $ Value = $ xmlfile-> GetElementsByTagName ('price'); Foreign Currency ($ value as value $) {$ value = $ value- & gt; Items (0) - & gt; Node vela; Echo "& lt; h1> gt; value & lt; / h1 & gt;"; }}? & Gt;

I'm just trying to output value tag values, because if it displays content then there should be no problem. Eventually, I will show these values ​​one at a time in the HTML structure.

Edit: At the moment the output of this code 

  wash 1 hatch / sedan: $ 15 hatch / sedan: $ 15 hatch / sedan: $ 15 hatch / sedan: $ 15 Wash 2 Hatch / sedan: $ 15 hatch / sedan: $ 15 hatch / sedan: $ 15 hatch / sedan: $ 15

You will get two bugs. As mentioned in another answer, you are receiving $ value from the wrong element: 

  $ value = $ xmlfile-> GetElementsByTagName ('value');

... should be: 

  $ value = $ service-> GetElementsByTagName ('price');

This does not completely fix the problem, however, because there is another problem you are getting through the prices, but then always the first & lt; Price & gt; Returning . You need to change it: 

  $ value = $ value-> Items (0) - & gt; Nodeville;

... on: 

  $ value = $ value-> Nodeville;

The correct code is then done: 

  & lt ;? Php header ('content-type: text / html; charset = UTF8'); $ Xmlfile = new DOMDocument (); $ Xmlfile-> Load ('services.xml'); $ Services = $ xmlfile-> GetElementsByTagName ('service'); Foreign Currency ($ Service $ as Service) {$ titles = $ Service-> GetElementsByTagName ('title'); $ Title = $ title- & gt; Items (0) - & gt; Node vela; Echo "
 Title = / h1>"; $ Value = $ service-> GetElementsByTagName ('price'); Forex currency ($ value as value $) {$ price = $ price- & gt; NodeValue; Echo "& lt; h1> gt; value & lt; / h1 & gt;"; }}

... which outputs:

wash 1

hatch / sedan: $ 15

Other: $ 20

Wash2

Hatch / sedan: $ 30

Other: $ 38

You have asked when it is necessary to use item () It basically depends on whether you (a domododist ) Or (or DOMNode ) Gives getElementsByTagName a DOMNodeList (can have many elements) so that you need to select a single, eg: 

  $ Titles = $ Service-> GetElementsByTagName ('title'); // A 'Domoddlist' returns with all the titles $ title = $ titles-> Items (0) - & gt; Nodeville; // Only the first title

you can repeat through a DOMNodeList (this applies traversal ). When you iterate you get a domonode : 

  $ value = $ service-> GetElementsByTagName ('value'); // Returns a `domonodelt 'foreign currency ($ value as $ value) {// $ value a' domoded` // ...}

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
