A區內的HTML文本A

Question

我使用Gumbo解析CP1251中的網頁。我已將文本轉換爲UTF-8並將它發送給了gumbo解析器。我有問題，獲取文本里面A鏈路與

node->v.text.text 

我得到的輸出奇怪的符號，而源在控制檯中正確顯示。 我使用Qt 5.2和libiconv進行轉換。

需要我將節點文本轉換爲本地代碼頁或我做錯了什麼？

獲取頁面CP1251

QByteArray barrData = pf->getData(); 

    size_t dstlen = 1048576; 
    char buf[dstlen]; 
    memset((char*)buf, 0, dstlen); 

    char* pIn = barrData.data(); 
    char* pOut = (char*)buf; 

    size_t srclen = barrData.size(); 


    iconv_t conv = iconv_open("UTF-8", "CP1251"); 
    iconv(conv, &pIn, &srclen, &pOut, &dstlen); 
    iconv_close(conv); 

    GumboOutput* output = gumbo_parse(buf); 

    parsePage(output->root); 
    gumbo_destroy_output(&kGumboDefaultOptions, output); 

解析

if (node->v.element.tag == GUMBO_TAG_DIV && (_class = gumbo_get_attribute(&node->v.element.attributes, "class"))) 
{ 
    if (QString(_class->value) == "catalog-item-title") 
    { 
     qDebug() << "parsePage: found product, parsing..."; 

     GumboVector* children = &node->v.element.children; 
     for (int i = 0; i < children->length; ++i) 
     { 
      GumboNode* node = static_cast<GumboNode*>(children->data[i]); 

      GumboAttribute* href; 
      GumboAttribute* id; 

      if (node->v.element.tag == GUMBO_TAG_A && 
       (href = gumbo_get_attribute(&node->v.element.attributes, "href")) 
      ) 
      { 
       char buf[1024]; 
       memset(buf, 0, 1024); 
       int i = node->v.text.original_text.length; 
       memcpy(buf, node->v.text.original_text.data, i); 


       QString strTitle = buf; 
       Q_ASSERT(node->v.text.original_text.length > 0); 
       qDebug() << "parsePage: found product" << strTitle << href->value; 

       break; 
      } 
     } 
    } 
} 

來源頁面文字：

<div class="catalog-item-title"><a href="/textile/postelnoe-bele/korolevskoe-iskushenie-perkal/izmir_2/">Измир 2</a></div>

我終於抽了例子。文本包含在子節點內。

  if (node->v.element.tag == GUMBO_TAG_A && 
       (href = gumbo_get_attribute(&node->v.element.attributes, "href")) 
      ) 
      { 
       QString strTitle; 
       GumboNode* title_text = static_cast<GumboNode>*)(node->v.element.children.data[0]); 
       if (title_text->type == GUMBO_NODE_TEXT) 
       { 
        strTitle = title_text->v.text.text; 
       } 

       qDebug() << "parsePage: found product" << strTitle << href->value; 

       break; 
      }
