Why ist Book2 with a price of 2.0 found by [price>2.0] and it's not found by [price=2.0]?
The parser is case sensitive so "2" should not work and "2.0" should. Could you show the XML document you're using so I can test this?

Hello, thank you for the prompt answer, the XML-file ist generated by the example I posted.
Code:
<?xml version="1.0" encoding="iso-8859-1"?>

<bookstore>
 <book>
  <title>title1
   </title>
  <price>1.0
   </price>
  </book>
 <book>
  <title>title2
   </title>
  <price>2.0
   </price>
  </book>
 <book>
  <title>title3
   </title>
  <price>3.0
   </price>
  </book>
 <book>
  <title>title4
   </title>
  <price>4.0
   </price>
  </book>
 <book>
  <title>title5
   </title>
  <price>5.0
   </price>
  </book>
 </bookstore>

Sorry I missed that; I fixed this in version 1.02.
Both [price=2] and [price=2.0] will work now since AutoHotkey sees them as the same numbers in expressions.

PostPosted: April 12th, 2007, 11:05 pm 
This is my first post, so first of all hello everybody.
I'm learning XML now, and a have a problem. Here is my XML code

Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE tv SYSTEM "xmltv.dtd">

<tv generator-info-name="EPG4cplus - mfsav mod">
  <channel id="00000001">
    <display-name>CANAL+</display-name>
  </channel>
   <programme start="20070414005000" stop="20070414005500" channel="00000001">
    <title>NBA+++++</title>
    <category>nosequepassa</category>
  </programme>
  <programme start="20070414005500" stop="20070414015500" channel="00000001">
    <title>Caribe salvaje</title>
    <category>documentales naturaleza</category>
  </programme>
</tv>


I need to filter the start and stop attributes with actual datetime to show what program is on tv at the moment. and i have no luck.
please help me.
thanks

ough! my source code is:
Code:
#Include XPath.ahk
a = C:\down\autohotkey\xpath\cplus.xml
book := XmlDoc(a)
latest := XPath(book, "/tv/programme[@stop>=A_Now]/title[1]/text()")
MsgBox, %latest%
XmlDoc("test2.xml", latest)

Code:
latest := XPath(book, "/tv/programme[@stop>=" A_Now "]/title[1]/text()")
; A_Now in String is A_Now as String

BTW: test2.xml ist not XML, it just the string you receive

All function parameters are expressions so you have to seperate strings from variables like: "/tv/programme[@stop>=" . A_Now . "]/title[1]/text()"

Edit: Venia Legendi beat me to it, thanks :)

thanks for that quick response (and excuse me for my bad written english) to Ttitan and Venia Legendi
I've tried and works, but reading from http://www.w3.org/TR/xpath-functions/#func-current-dateTime
i've found that function and tried to chace A_Now with current-dateTime. Oh!, surprise i am blocked again.
Can you help me.

thanks in advance.

Those functions aren't supported since you can do most of those kind of calculations yourself with AutoHotkey. At the moment only text() and remove() work.

New in v1.03:
  • Changed function to return nothing if a node is not found
  • Fixed root '//' expression to be able to parse child nodes
  • Fixed text() function to retrieve only the highest level node content
  • Corrected position where new attributes were inserted

Known limitation: '//' will apply to child nodes if used

I encountered a small problem with XPath.

This example code:

Code:
#Include %A_ScriptDir%\XPath.ahk

settingsFile := XmlDoc(A_ScriptDir . "\settings.xml")

guiTitle := XPath(settingsFile, "/settings/window/@title/text()")
guiPosX := XPath(settingsFile, "/settings/window/@x/text()")
guiPosY := XPath(settingsFile, "/settings/window/@y/text()")
guiPosW := XPath(settingsFile, "/settings/window/@w/text()")
guiPosH := XPath(settingsFile, "/settings/window/@h/text()")

Gui, +Lastfound +Resize
hWnd := WinExist()

Gui, Add, Text, , Just testing...`n`nResize me, reposition me, and close me`n`nIf you reopen me`, the last saved settings will be used`nfor positioning.
Gui, Show, x%guiPosX% y%guiPosY% w%guiPosW% h%guiPosH%, %guiTitle%
Return

GuiClose:
   WinGetPos, nowX, nowY, nowW, nowH, ahk_id %hWnd%

   nowW := nowW - 8
   nowH := nowH - 54
   
   XPath(settingsFile, "/settings/window/@x/text()", nowX)
   XPath(settingsFile, "/settings/window/@y/text()", nowY)
   XPath(settingsFile, "/settings/window/@w/text()", nowW)
   XPath(settingsFile, "/settings/window/@h/text()", nowH)
   XmlDoc(A_ScriptDir . "\settings.xml", settingsFile)

   ExitApp
Return


and this corresponding settings.xml file

Quote:
<?xml version="1.0" encoding="UTF-8"?>

<settings>
<window title="XPath Test" x="10" y="11" w="271" h="91">
</settings>


Every time after I wrote the values back to the file, the file has extra empty lines at the top.

Quote:
<?xml version="1.0" encoding="UTF-8"?>


<settings>
<window title="XPath Test" x="10" y="11" w="271" h="91">
</settings>


Quote:
<?xml version="1.0" encoding="UTF-8"?>




<settings>
<window title="XPath Test" x="10" y="11" w="271" h="91">
</settings>


... etcetera. Could this be fixed?

A new line character does get added for me, between all main/parent nodes btw after a save, not only at the top of the document... weird

Have you got the latest version 1.03? Try downloading xpath.ahk again, but rather than copying the text click 'Save As...' on the link so characters don't get somehow converted.
