こんにちは、stackoverflow XML と Ruby で引き続き問題が発生しています。
# rexml
xmlfile = File.new("sample.xml")
xmldoc = REXML::Document.new xmlfile
root = xmldoc.root
# count = 0
XPath.each( xmldoc, "//CRDoc/speech/speaking") do |element|

# puts element.text
File.open(file_name + "_" + element.attributes['name'] + "-" + year + ".xml", 'a+') do |f|

上記のコードは、この投稿に含まれる XML ファイルを読み取ります。このコードで私が抱えている問題は、XML ファイル内の個々のスピーチを新しい XML ファイルに書き込むのではなく、同じスピーチを何度も選択することです。

<speech> <speaker name="Mr. FAZIO">Mr. FAZIO</speaker>.<speaking name="Mr. FAZIO">I appreciate my friend yielding.</speaking>
<speaking name="Mr. FAZIO">I, too, would like to add a few words of tribute to our friend.</speaking>
<speaking name="Mr. FAZIO">When the 103d Congress came to an official close on noon Tuesday, the
House literally lived on for the next 24 hours in the person of the
gentleman from Sacramento, CA, the Clerk of the House, Donnald K.
Anderson. In serving as the first presiding officer for the purpose of
organizing the 104th Congress, he fulfilled his last ministerial duty
to this institution. After four successive terms as Clerk and a career
with the House that began as a Page when Dwight Eisenhower was
President and Sam Rayburn sat in the Speaker's chair, Donn Anderson now
leaves a distinguished career of public service.</speaking>
<speaking name="Mr. FAZIO">On a personal level for many of us in this Chamber, it was only
natural for Donn Anderson to have been the thread of continuity from
one Congress to the next. For over 30 years, Donn has embodied every
good virtue of this House. He has been its memory, its defender, its
champion and often its conscience. He understood perhaps better than
anyone here the meaning of the word ``bipartisanship'' and he lived it
daily in his work with the Members. In his 8 years as the second
highest ranking officer of the House, he worked tirelessly to move the
House into the information age and so greatly benefited our
constituents, the American people.</speaking>
<speaking name="Mr. FAZIO">As chairman of the Subcommittee on Legislative Appropriations, I
looked forward to our annual ritual of hearings knowing that I could
always count on the Clerk for the most splendid testimony. Although
Donn himself admitted to his preference for Victorian manners, there
was nothing old-fashioned about the direction of his office. He was
thoroughly modern in his vision for the future of the House, and he
fought hard to keep us current with the times. Just as Donn could
explain the artistic nuances of paintings in the Rotunda, he could just
as easily give you the technical lowdown of cameras in this Chamber and
on this floor. As the House moves forward today with the institutional
reforms and the reorganization, we do so with the solid foundation left
behind by Donn Anderson.</speaking>
<speaking name="Mr. FAZIO">Perhaps in parting we can borrow a phrase from our late and great
Speaker Tip O'Neill. He simply said on so many occasions, ``So long,
old pal.''</speaking>
<speaking name="Mr. FAZIO">Thank you, Donn Anderson.</speaking></speech>

したがって、上記のコードを実行すると、サンプル内のスピーカーごとに 1 つの XML ファイルが作成されます。次に、同じスピーチでいくつかのスピーチ/スピーカー ノードを作成します。私が理解できないのは、なぜ REXML がノードをトラバースせず、同じスピーチを何度も繰り返すのではなく、各スピーチを挿入しないのかということです。
コードを記述するためのより良い方法があると確信していますが、XML と XPath を扱うのは初めてです。
ありがとう！
