[digester] how can I print children tags instead of only tag content ?
I need to print the content of <categ> in my XML file (including children
tags).
For example, if I have <categ><child></child></categ>, I want to print
"<child></child>"
I'm currently parsing the xml file with:
digester.addCallMethod("collection/doc/categ",
"checkCateg", 0);
and this is the checkCateg function:
public void checkCateg(String categ) {
System.out.println(categ);
}
It doesn't work. The string categ is always empty because it only contains
text content in <categ> but not its children tags.
thanks,
Patrick

Re: [digester] how can I print children tags instead of only tag
content ?
Posted by Simone Tripodi <si...@apache.org>.
IIUC = if I understand correctly ;)
A quick hint: why don't you manage the logic inside your business
logic? I mean, you configure the digester:
Digester digester = new Digester();
digester.setRules( new RegexRules( new SimpleRegexMatcher() ) );
digester.addCallMethod( "collection/doc/categ/*", "myMethod", 0 );
then check the 'myMethod' has already been invoked:
boolean check = false;
public void myMethod( String arg )
{
if ( !check )
{
System.out.println( arg );
check = true;
}
}
HTH, let me know your progress!

Re: [digester] how can I print children tags instead of only tag
content ?
Posted by Patrick Diviacco <pa...@gmail.com>.
what does IIUC mean ?
Yeah. I mean, more exactly, I just need to know if the element has at least
a child:
bool = hasChild(myPattern)
thanks

IIUC, no matters which kind of children your node has, you're
interested only on the first child, right?

ps. the children names are completely different, there is no way to use a
regex to discriminate between them.

Re: [digester] how can I print children tags instead of only tag
content ?
Posted by Patrick Diviacco <pa...@gmail.com>.
hi Simone,
ok, it was just matter of adding one line :)
By the way I still have an issue in the case of multiple children and I
don't know how to solve it. If I have a document containing:
<parent>
<child1></child1>
<child2></child2>
</parent>
I don't want to trigger the method twice, but just once... in other terms I
want to trigger the method only once per document and only if the <parent>
tag has at least 1 child.
I copy my code again:
Digester digester = new Digester();
digester.setRules( new RegexRules( new SimpleRegexMatcher() ) );
digester.addCallMethod("collection/doc/categ/*", "myMethod", 0);
thanks
Patrick

Re: [digester] how can I print children tags instead of only tag
content ?
Posted by Simone Tripodi <si...@apache.org>.
Hi Patrick,
I thought it was more intuitive, sounds we have to update de doc.
Anyway, to reply to your questions:
1) just create the Digester instance, set the RegexRules and start
binding your rules:
Digester digester = new Digester();
digester.setRules( new RegexRules( new SimpleRegexMatcher() ) );
digester.addCallMethod( "collection/doc/categ/*", "myMethod", 0 );
2) yes, as reported in the javadoc I pointed: "* matches any sequence
of none, one or more characters" like in the bash syntax; if you want
to apply kind of filters, bind the rules with restrictive patterns
(prefixes/postfixes); ie. given the rule:
digester.addCallMethod( "collection/doc/categ/patt*", "myMethod", 0 );
collection/doc/categ/patt -> matches
collection/doc/categ/pattern -> matches
collection/doc/categ/patteRn -> matches
collection/doc/categ/pattern -> matches
collection/doc/categ/paBtern -> does not match
HTH, have a nice weekend,
Simo

Re: [digester] how can I print children tags instead of only tag
content ?
Posted by Patrick Diviacco <pa...@gmail.com>.
Thanks,
1) Is there any tutorial explaining how to use it ?
2) In my case, if I have more than one child, is the pattern detected
multiple times ?
help is very appreciated!

Hi Patrick,
follow the Konstantin's suggestion, that's the way to achieve it. Have
a read also to http://commons.apache.org/digester/apidocs/index.html?org/apache/commons/digester/SimpleRegexMatcher.html

The "*" is allowed in the prefix only, as documented in
http://commons.apache.org/digester/commons-digester-2.1/docs/api/org/apache/commons/digester/RulesBase.html
You may try to use a different rules matcher. See "RegexMatchers" chapter here:

mhm, sorry.. just to be more clear.
Is there a way in Commons Digester to trigger a method only if a xml element
has a child ?
i.e.
digester.addCallMethod("collection/doc/categ/*", "myMethod", 0);
This doesn't work. But it is actually what I need. If element <categ> has at
least a child, then trigger myMethod
thanks
