XML is case-sensitive so you need to use /book/Gen/text() since your file starts with <book>.

The docs says "there should be at least one space on each side of the period" for concatenation so you should use " . Book . " |

|
|
Hi,
Your example script is wrong, and drove me nuts figuring it out.
New script based on what you wrote:
| Code: | #Include xpath.ahk ; include functions
; creating documents:
xpath_load(feed)
xpath(feed, "/rss[+1]/@version", "2.0") ; create 'rss' node with attribute 'version'
xpath(feed, "/rss/channel[+1]/title[+1]", "second") ; rss > channel > title
xpath(feed, "/rss/channel/title[-1]", "first") ; '-1' puts this node before the last
xpath_save(feed,"test.xml") ; write XML |
Note that xpath takes feed as the first param, and test.xml as the 2nd one. When I ran your example (which was a pain to copy and paste out of explorer by the way) it gave me multiple errors.. Complaining that you had to have a byRef param to the xpath_save... And I figured out that I needed to call xpath_load() at the first (maybe not, as I finally got the end to work) and that I needed the #Include...
However, it seems to have created a file.. However, is this right??
| Code: | <?xml version="1.0" encoding="iso-8859-1"?>
<rss 2.0>
<channel>firstsecond</channel>
</rss> |
Seems like it should have been <rss version=2.0>
And the <channel>firstsecond</channel> seems messed up too...
What am I missing here?

| When I put /text() after every xpath it worked for me. I guess the examples in the documentation was copied (without testing) from the v2 branch in which the text function is implicit. I don't understand what you mean with the ByRef error though, because 'feed' is a variable. |

Read up on Libraries of Functions. #Include is not necessary if you put the script in the right place. |

I changed the code from the example:
| Code: | | xpath_save(feed,"test.xml") ; write XML |
which gives the error, to:
| Code: | | xpath_save("test.xml",feed) ; write XML |
which does not.
So, if I understand you right, the code should be:
| Code: | xpath_load(feed)
xpath(feed, "/rss[+1]/@version/text()", "2.0") ; create 'rss' node with attribute 'version'
xpath(feed, "/rss/channel[+1]/title[+1]/text()", "second") ; rss > channel > title
xpath(feed, "/rss/channel/title[-1]/text()", "first") ; '-1' puts this node before the last
xpath_save(feed,"test.xml") ; write XML |
(Just tested this, it gives a valid xml file)
Thanks for the help, this is pretty cool.. Maybe I can automate a bunch of the busy work that gets done around here.... (a 5 second code change takes 4 hours of work to get it pushed into Regression testing due to the documentation of the change... I.E. I changed for (I=0; I < 5; I++) to for (I=0; I < 10; I++) to change the number of years displayed in a combo box from now+5 years to now+10.. Expected impact: zero.. Oh, well...
Thanks,
-Chert

|
|
I have been trying to add in the task in an exisiting Bonsai outline task using Xpath.
Following is the code
| Code: | <items xml:space="preserve">
<item id="1702126217" type="simple" custom1="31" create-date="15 May 2007 05:45" last-modified="04 Mar 2008 11:35" pos-hint="2147483648" modified="#40">
<text>Processing</text>
<items>
<item id="1702126249" type="todo" create-date="04 Mar 2008 09:17" last-modified="04 Mar 2008 11:35" percent-complete="0" pos-hint="0" modified="#240">
<text>Call Fred about the book</text>
</item>
</items>
</item>
</items>
|
In the first place I dont know whether this format of XML is fine to use with xpath.
Following is the code I used in autohotkey to retrieve the text
| Code: | #Include XPath.ahk
sXMLFullPath =xpath_load("GTD-Inbox.OTL")
toutline= % xpath(sXMLFullPath, "/items/item/text()")
msgbox %toutline%
|
Whenever I run this program I get a blank message box.
Thank you very much for your help. |

| You forgot to use the expression-type assignment sXMLFullPath := xpath_load |

Hi Oberon, thanks for your immediate reply. I changed it to the expression but it did not work.
In the first place can anyone tell me whether the xml format I have mentioned in the earlier post will work with xpath. |

Your usage is incorrect. According to the manual, the return value is "False if there was an error in loading the document, true otherwise." The first parameter should be the variable you want to load the XML into, and the second should be the name of the file to load from.
| Code: | xpath_load(xml, "GTD-Inbox.OTL")
toutline := xpath(xml, "/items/item/text()")
msgbox %toutline% |
If the second parameter is omitted, the first parameter is converted from XML into a format xpath can use.
| Code: | xml =
(
<items xml:space="preserve">
<item id="1702126217" type="simple" custom1="31" create-date="15 May 2007 05:45" last-modified="04 Mar 2008 11:35" pos-hint="2147483648" modified="#40">
<text>Processing</text>
<items>
<item id="1702126249" type="todo" create-date="04 Mar 2008 09:17" last-modified="04 Mar 2008 11:35" percent-complete="0" pos-hint="0" modified="#240">
<text>Call Fred about the book</text>
</item>
</items>
</item>
</items>
)
xpath_load(xml)
toutline := xpath(xml, "/items/item/text()")
msgbox %toutline% |

Thank you lexiKos, that worked for me. But I have another problem, when the xml file starts with the tag <bonsai-outline> the script display only an empty message box.
| Code: | <bonsai-outline>
<items>
<item>
<text></text>
</item>
<item>
<text></text>
</item>
</items>
</bonsai-outline>
|
But when I change bonsai-outline tag to bonsaioutline without the hypen then the script displays the value of the text tag.
Titan, can you please let me know whether this is a problem in the script or by default the tags should not have an hypen.
Thank you very much. |

This line works in 3.10rc3 but it doesn't work with the newest version 3.13. What things have changed in the syntax since then?
| Code: |
DealtPlayersNames := xpath(hand, "/HandDetails/DetailLines/DetailLine[@Action='Seat'][@PlayerName]/@PlayerName/text()")

| I haven't modified xpath in months. Could you post your XML file or at least a sample of it which fails to produce the desired result? Also can you confirm that you have the latest version, 3.13c? |

Sure. Here is a code example. This message box shows names with XPath 3.10rc3 but shows blank with 3.13. Thanks for helping and also for being so quick!
| Code: |
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
#Include XPath.ahk

| Removing [@PlayerName] in your expression worked for me. I don't know why this is, presumably because the attribute in question is part of the request which causes conflicts somehow - short cut optimisation perhaps? Regardless it is a bug as it breaks standard so I will have to fix it in future. |
