Parsing XML Tags Help

[ralphNOSPAM@primemail.com]

Is there a function or otherwise some way to pull out the target text
within an XML tag?

For example, in the XML tag below, I want to pull out 'CALIFORNIA'.

<txtNameUSState >CALIFORNIA</txtNameUSState>

There are at least two PHP extensions that allow parsing XML:

http://www.php.net/XML

http://www.php.net/DOMXML

There's also the SimpleXML extension, but it requires PHP 5.

If this is all you want, you can simply do

$state = strip_tags('<tx tNameUSState>CA LIFORNIA</txtNameUSState> ');

or use regular expressions.

There are multiple tags I need to strip out of the xml image so your
$state = example wouldn't work. Sorry, I was trying not to get too
deep.

I did read the php xml extension before I posted but I got lost.

I was hoping there was a function that would pull out the text between
an xml tag. If there is such a function in the php xml extensions I
couldn't see it ir otherwise figure it out.

Something like (obviously untested)

# define parser

$parser = xml_parser_crea te();
xml_set_element _handler($parse r, "startEleme nt", "endElement ");
xml_set_charact er_data_handler ($parser, "characterData" );

# define some variables used later

$saving=0;
$text='';

# open the xml file, read some data, details not shown

OPEN YOUR FILE
$data = GET SOME DATA() ... fread etc ...

# feed data to parser

while ($data != '')
{
if (!xml_parse($pa rser, $data, ? READ THE API )
{
$err =
sprintf( "XML error: %s, at line %d, column %d\n"
, xml_error_strin g(xml_get_error _code($parser))
, xml_get_current _line_number($p arser)
, xml_get_current _column_number( $parser)+1
);
die($err);
}
$data = GET SOME DATA() ... fread etc ...
}
xml_parser_free ($parser);

# When you get here, then parsing has finished. If you saved the text in
# an array (below) then that array would be full of strings by now.

print "All done!";

#
# the functions below get called to handle the data during the parsing
#

function startElement($p arser, $tagname, $attrs)
{
if ($tagname == "txtNameUSState ")
{
$saving++;
}
}

function endElement($par ser, $tagname)
{
if ($tagname == "txtNameUSState ")
{
$saving--;
}

if ($saving==0)
{
# OR save $text in an array - not shown
do_something_wi th_the_text( $text );


# BUT either way, you must clear the text string
# ready for the next tag

$text='';
}

}

function characterData($ parser, $data)
{
if ($saving > 0)
{
$text .= $data;
}
}

# ----- END oF PROGRAM


I show calling a function for each bit of text. Another thing to do would
be to push each string into an array. After the while/parse loop is
finsihed then you would have an array of strings.

Well, then you need to use an XML extension of some sort. Let's say
your XML is stored at http://www.example.com/file.xml. Then you can
try something like this:

$content = file_get_conten ts('http://www.example.com/file.xml');
$p = xml_parser_crea te();
xml_parse_into_ struct($p, $content, $vals, $index);
xml_parser_free ($p);
unset($content) ;
foreach ($index['txtNameUSState '] as $key => $id) {
$value = $vals[$id]['value'];
// now $value contains the text inside <txtNameUSState > tags
}
