RegExp help needed!
Hi all,
I'm fumbling my way around Ant and finding the help on the web really
confusing. I am using Ant simply as a macro copy/download/find-replace
utility and am an ActionScript programmer, not a Java one.
Anyway... There's one bit I'm stuck on and really need your help please!
I have used Ant to download an XML file and store it locally. I now need a
way of going through the XML, finding all the image URL attributes,
downloading those images and replacing all the URLs in the XML to local
relative paths. So far, all I have is:
<loadfile property="questions" srcFile="${local.path}GetAllQuestions.xml"
/>
<propertyregex input="${questions}" property="questions.output"
regexp="Media="(.*?)"" select="\1" global="true" />
<echo message="${questions.output}" />
This only traces the first one in the XML, but obviously I want to find all
of the instances, add them to some kind of array and then loop through that
array and load them all. I've done a for list before so that bit is okay,
but the question is how do I get Ant to iterate through and find all
individual instances of that regexp?
Please help... Thanks!
:-Joe

Okay,
So I've sorted it, but it was a weird one!
One of the questions was badly formatted, and looked like this:
<Question ID="531" Subject="L" Category="Punc" Presentation="PT01"
Engine="MC01" Body="test" Instruction="Select the correct answer" Level="1">
<TipID/>
<Answers>
<Answer ID="1457" Valid="false" Position="1"
Media="/bgmain/Image.ashx?ID=112">[Media}</Answer>
<Answer ID="1458" Valid="true" Position="2"
Media="/bgmain/Image.ashx?ID=113">[Media}</Answer>
<Answer ID="1459" Valid="false" Position="3"
Media="/bgmain/Image.ashx?ID=114">[Media}</Answer>
<Answer ID="1460" Valid="false" Position="4"
Media="/bgmain/Image.ashx?ID=115">[Media}</Answer>
</Answers>
</Question>
Notice the "[Media}"... Now the weird thing is that this caused an error on
a large file, but not on a smaller one. I can correct the problem from my
end, but I thought you might like to know! Is a "}" symbol not allowed in
UTF-encoded XML files? It seems to work fine in a browser and like I said,
also works fine in smaller files...
weird!

Hi there,
Just so you know, I created a file which was bigger than my original file as
a test, and that worked fine... So I'm a bit confused as to how this XML
file will not work when it is supposedly well formatted...
??

Hi,
uhhm, in this case maybe the error you are encountering is a disguised
Out of Memory, or a bug with the XML parser.
you might want to try with different JDKs. I do not know whether the
xercesImpl.jar which ships with ant is actually used to parse XML files
in custom tasks or whether it would be some equivalent package from your
JDK. I wonder whether ant would run without the xercesImpl.jar. I guess
it is not needed with the recent JDKs.

Antoine

Hi Antopine,
Yes the XML file loads fine in a browser. I am even declaring UTF-8 at the
top of the file. And when I split the file down the middle and test both
halves (keeping the header of course) it works fine too.
Hello,
the error below would not be an ant of xmltask error. The message
Invalid byte 3 of 3-byte UTF-8 sequence
means that your XML file is not matching the UTF-8 convention. Does
your XML file specify UTF-8 in the XML declaration ?
Can you read your XML file using another tool than ant, for instance a
web browser, or the XML editor of Eclipse or another Java based
development environment ?
Regards,
Antopine

Thanks for the info. If you are right, this could still be a problem because
the XML is being formed on a server and I don't really have control over
that part of it!
I just tried splitting the file into two to test that theory... Both halves
seem to work fine, but together they throw that error.
I also ran the XML file in Firefox to see what it thinks of the file, and it
doesn't throw any encoding errors.
:(

Doh... Looks like I have a problem using xmltask anyway unfortunately... The
GetAllQuestions.xml is too big for it to handle :-( it's nearly 1MB in size.
At least I'm pretty sure that's why, since if I run another piece of XML
which is a lot smaller it works fine. But in this case I get the error:

RE: RegExp help needed!
Posted by Jowie <jo...@mac.com>.
Okay... So back to my original request (thanks for all the help so far! :))
Here's my code so far:
------------
<target name="downloadQuestionImages">
<xmltask source="${local.path}GetAllQuestions.xml">
<call path="//@Media" target="getMedia">
</call>
</xmltask>
</target>
<target name="getMedia">
<echo message="${mediaURL}" />
</target>
-------------
This doesn't seem to iterate through though... I get:
getMedia:
[echo] /brain_games_main/Image.ashx?ID=647
[xmltask] Parent project doesn't contain any reference 'xmltask.buffers'
And just keeps looping.
Any thoughts? Thanks!

I think the problem that I have is that the @Media property isn't always set.
In which case it fails when it tries to look at a node with no Media
property.
Can anyone think of a workaround? :-/
Thanks!

Hopefully it will work this time... This is my code:
<![CDATA[
<target name="downloadQuestionImages">
<xmltask source="${local.path}GetAllQuestions.xml">
<call path="//@Media" buffer="media">
<actions>
<echo>img = @{img}</echo>
</actions>
</call>
</xmltask>
</target>
]]>
and I get back:
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
etc....
Sorry everyone for the repeat postings! I'm really starting to scratch my
head sore on this one! :-/

Hi Gilbert,
Sorry my copied code was completely wrong! Have no idea why! It should have
been:
<xmltask source="${local.path}GetAllQuestions.xml">
<call path="//*">
<actions>
<echo>img = @{img}</echo>
</actions>
</call>
</xmltask>
And I get back:
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647
[echo] img = /brain_games_main/Image.ashx?ID=647

Hopefully that will be it now... ;-)

Hi Gilbert,

Hi Gilbert,
Thanks very much for taking the time to help me out. Unfortunately I've not
used Xpath before and don't really have time to learn :( but if I give you
an example of my XML, could you perhaps point me in the right direction?
Here is an example:
------
<Question ID="531" Subject="L" Category="Punc" Presentation="PT01"
Engine="MC01" Body="test" Media="/bgmain/Image.ashx?ID=12">
<TipID/>
<Answers>
<Answer ID="1457" Valid="false" Position="1"
Media="/bgmain/Image.ashx?ID=112">txt</Answer>
<Answer ID="1458" Valid="true" Position="2"
Media="/bgmain/Image.ashx?ID=113">txt</Answer>
<Answer ID="1459" Valid="false" Position="3"
Media="/bgmain/Image.ashx?ID=114">txt</Answer>
<Answer ID="1460" Valid="false" Position="4"
Media="/bgmain/Image.ashx?ID=115">txt</Answer>
</Answers>
</Question>

So from this, I need to:
1. Find any Media attribute, nested or otherwise (e.g. in E4X,
questionXML..@Media)
2. Store each of these to download them

Hi all,
I'm fumbling my way around Ant and finding the help on the web really
confusing. I am using Ant simply as a macro copy/download/find-replace
utility and am an ActionScript programmer, not a Java one.
Anyway... There's one bit I'm stuck on and really need your help please!
I have used Ant to download an XML file and store it locally. I now need a
way of going through the XML, finding all the image URL attributes,
downloading those images and replacing all the URLs in the XML to local
relative paths. So far, all I have is:
<loadfile property="questions" srcFile="${local.path}GetAllQuestions.xml"
/>
<propertyregex input="${questions}" property="questions.output"
regexp="Media="(.*?)"" select="\1" global="true" />
<echo message="${questions.output}" />
*/
regexp for xml or html is not recommended, better use xmltask and the power of xpath =
xmltask
http://www.oopsconsultancy.com/software/xmltask/
xpath
http://www.w3schools.com/Xpath/
http://www.zvon.org/xxl/XPathTutorial/General/examples.html
so you would go like that =
<xmltask source="">
<call path="//module/*[liefertyp/text()='build']" target="yourdownloadtarget">
<param name..." path="..."/>
...
</call>
</xmltask>
you may post a snippet of your xml file to get the right xpath expression.
Regards, Gilbert
