I have a xml file like this :

<data>
<season id="00">
    <project id="text"/>
    <project id="test"/>
    <project id="move"/>
    <project id="moser"/>
    <project id="moment"/>
    <project id="save"/>
    <project id="safe"/>
    <project id="search"/>      
</season>
<season id="01">
    <project id="send"/>
    <project id="serve"/>
    <project id="service"/>
    <project id="mondey"/>
    <project id="mother"/>
    <project id="tesla"/>
    <project id="tiser"/>
    <project id="spacnk"/>      
</season>

I want to find xmllist with regexp for match some text in attributes for example “se” or “mo”.
Please help me.

Answer 1

var xml:XML = 
<data>
    <season id="00">
        <project id="text"/>
        <project id="test"/>
        <project id="move"/>
        <project id="moser"/>
        <project id="moment"/>
        <project id="save"/>
        <project id="safe"/>
        <project id="search"/>
    </season>
    <season id="01">
        <project id="send"/>
        <project id="serve"/>
        <project id="service"/>
        <project id="mondey"/>
        <project id="mother"/>
        <project id="tesla"/>
        <project id="tiser"/>
        <project id="spacmonk"/>
    </season>
</data>;

trace( xml..project.( @id.match( /se/ ) ).toXMLString() );

Explanation:

xml     // using the XML data in our xml variable
..      // find descendants at any level
project // that is an element of type project
(       // open an expression to evaluate
@id     // using attribute 'id' of our project elements
.match( // find matching 'id' values using regular expression
/se/    // find the string 'se' anywhere in the string that is evaluated
)       // close match()
)       // close expression

To match only project elements with id attributes that start with “se” you simply have to alter the regular expression as usual:

/^se/

And ending with “se”:

/se$/

… etc.
